(PHP 4, PHP 5)
substr — 文字列の一部分を返す
説明
string substr ( string $string, int $start [, int $length] )substr() は文字列 string の、start で指定された 位置から length バイト分の文字列を 返します。
start が正の場合、返される文字列は、 string の 0 から数えて start番目から始まる文字列となります。 例えば、文字列'abcdef'において位置 0にある文字は、'a'であり、 位置2には'c'があります。
例 2423. substr() の基本的な使用法
<?php
echo substr('abcdef', 1); // bcdef を返す
echo substr('abcdef', 1, 3); // bcd を返す
echo substr('abcdef', 0, 4); // abcd を返す
echo substr('abcdef', 0, 8); // abcdef を返す
echo substr('abcdef', -1, 1); // f
// 文字列中の 1 文字にアクセスすることも
// "中括弧" を使用することで可能
$string = 'abcdef';
echo $string{0}; // a を返す
echo $string{3}; // d を返す
echo $string{strlen($string)-1}; // f を返す
?>
start が負の場合、返される文字列は、 stringの後ろから数えて start番目から始まる文字列となります。
例 2424. 負のstartを使用
<?php
$rest = substr("abcdef", -1); // "f" を返す
$rest = substr("abcdef", -2); // "ef" を返す
$rest = substr("abcdef", -3, 1); // "d" を返す
?>
length が指定され、かつ正である場合、 返される文字列は start (string の長さに依存します) から数えてlength文字数分となります。 もし string が start の文字列長より小さいもしくは等しい場合、FALSE が返されます。
length が指定され、かつ負である場合、 string の終端から多くの文字が省略されます (start が負の場合、 開始位置は文字列の終端を過ぎているので) 。 もし start が切り出し位置を超える場合、 空文字が返されます。
例 2425. 負のlengthを使用
$rest = substr("abcdef", 0, -1); // "abcde"を返す
$rest = substr("abcdef", 2, -1); // "cde"を返す
$rest = substr("abcdef", 4, -4); // ""を返す
$rest = substr("abcdef", -3, -1); // "de"を返す
strrchr()、 substr_replace()、 preg_match()、 trim()、 mb_substr() および wordwrap() も参照ください。

I wanted to work out the fastest way to get the first few characters from a string, so I ran the following experiment to compare substr, direct string access and strstr:
<?php
/* substr access */
beginTimer();
for ($i = 0; $i < 1500000; $i++){
$opening = substr($string,0,11);
if ($opening == 'Lorem ipsum'){
true;
}else{
false;
}
}
$endtime1 = endTimer();
/* direct access */
beginTimer();
for ($i = 0; $i < 1500000; $i++){
if ($string[0] == 'L' && $string[1] == 'o' && $string[2] == 'r' && $string[3] == 'e' && $string[4] == 'm' && $string[5] == ' ' && $string[6] == 'i' && $string[7] == 'p' && $string[8] == 's' && $string[9] == 'u' && $string[10] == 'm'){
true;
}else{
false;
}
}
$endtime2 = endTimer();
/* strstr access */
beginTimer();
for ($i = 0; $i < 1500000; $i++){
$opening = strstr($string,'Lorem ipsum');
if ($opening == true){
true;
}else{
false;
}
}
$endtime3 = endTimer();
echo $endtime1."\r\n".$endtime2."\r\n".$endtime3;
?>
The string was 6 paragraphs of Lorem Ipsum, and I was trying match the first two words. The experiment was run 3 times and averaged. The results were:
(substr) 3.24
(direct access) 11.49
(strstr) 4.96
(With standard deviations 0.01, 0.02 and 0.04)
THEREFORE substr is the fastest of the three methods for getting the first few letters of a string.

If you need to divide a large string (binary data for example) into segments, a much quicker way to do it is to use streams and the php://memory stream wrapper.
For example, if you have a large string in memory, write it to a memory stream like
<?php
$segment_length = 8192; // this is how long our peice will be
$fp = fopen("php://memory", 'r+'); // create a handle to a memory stream resource
fputs($fp, $payload); // write data to the stream
$total_length=ftell($fp); // get the length of the stream
$payload_chunk = fread ( $fp, $segment_length );
?>
Working with large data sets, mine was 21MB, increased the speed several factors.

All the references to "curly braces" on this page appear to be obsolete.
According to http://us.php.net/manual/en/language.types.string.php
"Using square array-brackets is preferred because the {braces} style is deprecated as of PHP 6."

Starting from version 5.2.3 if $start is negative and larger then the length of the string, the result is an empty string, while in earlier versions the result was the string itself!
substr ("abcdef", -1000);
result in 5.2.0
'abcdef'
result in 5.2.3
''
This is a small inconsistency, one of those things that makes the life of a PHP programmer like hell.

JavaScript charAt PHP equivalent
<?php
function charAt($str, $pos)
{
return (substr($str, $pos, 1)) ? substr($str, $pos, 1) : -1;
}
?>
--------------------------------------------------------
There is a bug with the above code, if the charAt(..) is 0 it will return -1, because the conditional returns false.
Code below with minor fix works:
<?php
function charAt($str, $pos)
{
return (strlen(substr($str, $pos, 1))) ? substr($str, $pos, 1) : -1;
}

In PHP 5.2.2 (and probably 4.4.x) the behaviour of substr has changed for negative start index larger than the string length - now returning false in stead of the string itself. Read http://bugs.php.net/bug.php?id=41375

"substr" seems to be implemented in a sequential way, wasting processing power proportional to the length of the string to be worked on and/or the position of the substring to be extracted.
I found a speed increase by a factor of 1000 for string extraction when the original string has a size of about 1 MB, when i replace "substr" by direct access to the chars at their index.
"Substr" should not be used for extraction of very small pieces.

The functions submitted below are a waste of time and memory. To convert a string to an integer or a trimmed float, use the built in conversion instead of parsing the string, e.g :
<?php
$x = "27.2400";
echo (float)$x; // 27.24
echo (int)$x; // 27

Very nice a dot vanderkolk at gmail dot com, just what I needed.
I have taken your function and added a bit to it, it will strip out ALL the chars after the dot ("."). It would be useful if someone could post how to only strip if they are zeros, and round to 2 chars after the "." if they are not.
// Remove chars after . (200.000 => 200)
function removeDotZero($var)
{
$var = trim($var);
$pos = strpos($var,".");
if($pos != false)
{
$size = strlen($var);
for($i = $size; $i > $pos; $i--)
{
if(substr($var,-1,1) == "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9")
$var = substr($var,0,($i - 1));

A further addition to Jean-Felix function to extract data between delimeters.
The previous function wouldn't return the correct data if the delimeters used where long than one char. Instead the following function should do the job.
<?php
function extractBetweenDelimeters($inputstr,$delimeterLeft,$delimeterRight) {
$posLeft = stripos($inputstr,$delimeterLeft)+strlen($delimeterLeft);
$posRight = stripos($inputstr,$delimeterRight,$posLeft+1);
return substr($inputstr,$posLeft,$posRight-$posLeft);
}
?>

If you need to extract information in a string between delimeters then you can use this:
Inputstring is:
"Heidi Klum Supermodel" <info@HeidiKlum.com>
Here the script
<?php
$emailadresse = "\"Heidi Klum Supermodel\" <info@HeidiKlum.com>";
$outputvalue = extractBetweenDelimeters($emailadresse,"\"","\"");
echo $outputvalue; // shows Heidi Klum Supermodel
echo "<br>";
$outputvalue = extractBetweenDelimeters($emailadresse,"<",">");
echo $outputvalue; // shows info@HeidiKlum.com
function extractBetweenDelimeters($inputstr,$delimeterLeft,$delimeterRight) {
$posLeft = stripos($inputstr,$delimeterLeft)+1;
$posRight = stripos($inputstr,$delimeterRight,$posLeft+1);
return substr($inputstr,$posLeft,$posRight-$posLeft);
}

This function can replace substr() in some situations you don't want to cut right in the middle of a word. strtrim will cut between words when it is possible choosing the closest possible final string len to return. the maxoverflow parameter lets you choose how many characters can overflow past the maxlen parameter.
<?php
function strtrim($str, $maxlen=100, $elli=NULL, $maxoverflow=15) {
global $CONF;
if (strlen($str) > $maxlen) {
if ($CONF["BODY_TRIM_METHOD_STRLEN"]) {
return substr($str, 0, $maxlen);
}
$output = NULL;
$body = explode(" ", $str);
$body_count = count($body);
$i=0;
do {
$output .= $body[$i]." ";
$thisLen = strlen($output);
$cycle = ($thisLen < $maxlen && $i < $body_count-1 && ($thisLen+strlen($body[$i+1])) < $maxlen+$maxoverflow?true:false);
$i++;
} while ($cycle);
return $output.$elli;

It might be obvious to some but I took some time to figure it out that you can't call
<?php
$text = substr($text, 0, -0);
?>
and expect $text to be unchanged.
A bit of context might make the issue clearer. I'm calculating how many characters I need to chop of the end of the string and them I call substr as
<?php
$text = substr($text, 0, -$charactersToChop);
?>
Sometimes $charactersToChop is set to 0 and in this case I wanted $text to be unchanged. The problem is that in this case $text gets set to an empty string.
Why? Because -0 is the same as 0 and substr($text, 0, 0) obviously returns an empty string.
In case someone want a fix:
<?php
if ($charactersToChop) {
$text = substr($text, 0, -$charactersToChop);
}
?>
That's it.

a function to read in a file and split the string into its individual characters and display them as images for a webcounter.
can be used anywhere you need to split a string where a seperator is not present and versions where the str_split() function is also not present.

Here's a function I wrote that'll insert a string into another string with an offset.
// $insertstring - the string you want to insert
// $intostring - the string you want to insert it into
// $offset - the offset
function str_insert($insertstring, $intostring, $offset) {
$part1 = substr($intostring, 0, $offset);
$part2 = substr($intostring, $offset);
$part1 = $part1 . $insertstring;
$whole = $part1 . $part2;
return $whole;

Add on to "Matias from Argentina" str_format_number function.
Just added handling of $String shorter then $Format by adding a side to start the fill and a string length to the while loop.
function str_format_number($String, $Format, $Start = 'left'){
//If we want to fill from right to left incase string is shorter then format
if ($Start == 'right') {
$String = strrev($String);
$Format = strrev($Format);
}
if($Format == '') return $String;
if($String == '') return $String;
$Result = '';
$FormatPos = 0;
$StringPos = 0;
while ((strlen($Format) - 1) >= $FormatPos && strlen($String) > $StringPos) {
//If its a number => stores it
if (is_numeric(substr($Format, $FormatPos, 1))) {
$Result .= substr($String, $StringPos, 1);
$StringPos++;
//If it is not a number => stores the caracter
} else {
$Result .= substr($Format, $FormatPos, 1);
}
//Next caracter at the mask.
$FormatPos++;
}
if ($Start == 'right') $Result = strrev($Result);
return $Result;
}

Be careful when comparing the return value of substr to FALSE. FALSE may be returned even if the output is a valid string.
substr("0", 0); // equals "0", comparision with FALSE evaluates to true, because "0" == 0 == FALSE

Here's a little addon to the html_substr function posted by fox.
Now it counts only chars outside of tags, and doesn't cut words.
Note: this will only work in xhtml strict/transitional due to the checking of "/>" tags and the requirement of quotations in every value of a tag. It's also only been tested with the presence of br, img, and a tags, but it should work with the presence of any tag.
<?php
function html_substr($posttext, $minimum_length = 200, $length_offset = 20, $cut_words = FALSE, $dots = TRUE) {
// $minimum_length:
// The approximate length you want the concatenated text to be
// $length_offset:
// The variation in how long the text can be in this example text
// length will be between 200 and 200-20=180 characters and the
// character where the last tag ends
// Reset tag counter & quote checker
$tag_counter = 0;
$quotes_on = FALSE;
// Check if the text is too long
if (strlen($posttext) > $minimum_length) {
// Reset the tag_counter and pass through (part of) the entire text
$c = 0;
for ($i = 0; $i < strlen($posttext); $i++) {
// Load the current character and the next one
// if the string has not arrived at the last character
$current_char = substr($posttext,$i,1);
if ($i < strlen($posttext) - 1) {
$next_char = substr($posttext,$i + 1,1);
}
else {
$next_char = "";
}
// First check if quotes are on
if (!$quotes_on) {
// Check if it's a tag
// On a "<" add 3 if it's an opening tag (like <a href...)
// or add only 1 if it's an ending tag (like </a>)
if ($current_char == '<') {
if ($next_char == '/') {
$tag_counter += 1;
}
else {
$tag_counter += 3;
}
}
// Slash signifies an ending (like </a> or ... />)
// substract 2
if ($current_char == '/' && $tag_counter <> 0) $tag_counter -= 2;
// On a ">" substract 1
if ($current_char == '>') $tag_counter -= 1;
// If quotes are encountered, start ignoring the tags
// (for directory slashes)
if ($current_char == '"') $quotes_on = TRUE;
}
else {
// IF quotes are encountered again, turn it back off
if ($current_char == '"') $quotes_on = FALSE;
}
// Count only the chars outside html tags
if($tag_counter == 2 || $tag_counter == 0){
$c++;
}
// Check if the counter has reached the minimum length yet,
// then wait for the tag_counter to become 0, and chop the string there
if ($c > $minimum_length - $length_offset && $tag_counter == 0 && ($next_char == ' ' || $cut_words == TRUE)) {
$posttext = substr($posttext,0,$i + 1);

Regarding the utf8_substr function from lmak: The pattern '/./u' doesn't match newline characters. This means that the substring from 0 to the total length of the string will miss the number of characters in the end matching the number of newlines in the string. To fix this one can add the s modifier (PCRE_DOTALL) in the pattern:
<?php
function utf8_substr($str,$start)
{
preg_match_all("/./su", $str, $ar);
if(func_num_args() >= 3) {
$end = func_get_arg(2);
return join("",array_slice($ar[0],$start,$end));
} else {
return join("",array_slice($ar[0],$start));
}
}

This function shortens the string down to maximum lengt defined in $max_lengt. If the string is longer the function finds the last occurance of a space and adds three dots at the end to illustrate that it is more text. If the string is without spaces it stops at exacly max lengt, also adding three dots. If the string is shorter than max lengt it returns the string as it is. This is useful for previewing long strings.
function str_stop($string, $max_length){
if (strlen($string) > $max_length){
$string = substr($string, 0, $max_length);
$pos = strrpos($string, " ");
if($pos === false) {
return substr($string, 0, $max_length)."...";
}
return substr($string, 0, $pos)."...";
}else{
return $string;

I needed to cut a string after x chars at a html converted utf-8 text (for example Japanese text like 嬰謰弰脰欰罏).
The problem was, the different length of the signs, so I wrote the following function to handle that.
Perhaps it helps.
<?php
function html_cutstr ($str, $len)
{
if (!preg_match('/\&#[0-9]*;.*/i', $str))
{
$rVal = strlen($str, $len);
break;
}
$chars = 0;
$start = 0;
for($i=0; $i < strlen($str); $i++)
{
if ($chars >= $len)
break;
$str_tmp = substr($str, $start, $i-$start);
if (preg_match('/\&#[0-9]*;.*/i', $str_tmp))
{
$chars++;
$start = $i;
}
}
$rVal = substr($str, 0, $start);
if (strlen($str) > $start)
$rVal .= " ...";
return $rVal;
}

If you need just a single character from the string you don't need to use substr(), just use curly braces notation:
<?php
// both lines will output the 3rd character
echo substr($my_string, 2, 1);
echo $my_string{2};
?>
curly braces syntax is faster and more readable IMHO..

I have developed a function with a similar outcome to jay's
Checks if the last character is or isnt a space. (does it the normal way if it is)
It explodes the string into an array of seperate works, the effect is... it chops off anything after and including the last space.
<?
function limit_string($string, $charlimit)
{
if(substr($string,$charlimit-1,1) != ' ')
{
$string = substr($string,'0',$charlimit);
$array = explode(' ',$string);
array_pop($array);
$new_string = implode(' ',$array);
return $new_string.'...';
}
else
{
return substr($string,'0',$charlimit-1).'...';
}
}

This returns the portion of str specified by the start and length parameters..
It can performs multi-byte safe on number of characters. like mb_strcut() ...
Note:
1.Use it like this bite_str(string str, int start, int length [,byte of on string]);
2.First character's position is 0. Second character position is 1, and so on...
3.$byte is one character length of your encoding, For example: utf-8 is "3", gb2312 and big5 is "2"...you can use the function strlen() get it...
Enjoy it :) ...

Hmm ... this is a script I wrote, whitch is very similar to substr, but it isn't takes html and bbcode for counting and it takes portion of string and show avoided (html & bbcode) tags too ;]
Specially usefull for show part of serach result included html and bbcode tags
<?php
/**
* string csubstr ( string string, int start [, int length] )
*
* @author FanFataL
* @param string string
* @param int start
* @param [int length]
* @return string
*/
function csubstr($string, $start, $length=false) {
$pattern = '/(\[\w+[^\]]*?\]|\[\/\w+\]|<\w+[^>]*?>|<\/\w+>)/i';
$clean = preg_replace($pattern, chr(1), $string);
if(!$length)
$str = substr($clean, $start);
else {
$str = substr($clean, $start, $length);
$str = substr($clean, $start, $length + substr_count($str, chr(1)));
}
$pattern = str_replace(chr(1),'(.*?)',preg_quote($str));
if(preg_match('/'.$pattern.'/is', $string, $matched))
return $matched[0];
return $string;
}

Using this is similar to simple substr.

Well this is a script I wrote, what it does is chop up long words with malicious meaning into several parts. This way, a chat in a table will not get stretched anymore.
<?php
function text($string,$limit=20,$chop=10){
$text = explode(" ",$string);
while(list($key, $value) = each($text)){
$length = strlen($value);
if($length >=20){
for($i=0;$i<=$length;$i+=10){
$new .= substr($value, $i, 10);
$new .= " ";
}
$post .= $new;
}
elseif($length <=15){
$post .= $value;
}
$post .= " ";
}
return($post);
}
// for example, this would return:
$output = text("Well this text doesn't get cut up, yet thisssssssssssssssssssssssss one does.", 10, 5);
echo($output); // "Well this text doesn't get cup up, yet thiss sssss sssss sssss sssss sss one does."

Hello,
Here you are a function to format your
numeric strings. Enjoy it.
<?php
function str_format_number($String, $Format){
if ($Format == '') return $String;
if ($String == '') return $String;
$Result = '';
$FormatPos = 0;
$StringPos = 0;
While ((strlen($Format) - 1) >= $FormatPos){
//If its a number => stores it
if (is_numeric(substr($Format, $FormatPos, 1))){
$Result .= substr($String, $StringPos, 1);
$StringPos++;
//If it is not a number => stores the caracter
} Else {
$Result .= substr($Format, $FormatPos, 1);
}
//Next caracter at the mask.
$FormatPos++;
}
return $Result;
}
// For phone numbers at Buenos Aires, Argentina
// Example 1:
$String = "541143165500";
$Format = "+00 00 0000.000";
Echo str_format_number($String, $Format); // Returns "+54 11 4316.5500"
// Example 2:
$String = "541143165500";
$Format = "+00 00 0000.0000000";
Echo str_format_number($String, $Format); // Returns "+54 11 4316.5500"
// Example 3:
$String = "541143165500";
$Format = "+00 00 0000.000 a";
Echo str_format_number($String, $Format); // Returns "+54 11 4316.550 a"
?>
How it works explanation:
str_format_number($String, $Format)
Spects two parameters $String and $Format,
both should be strings.
$String: coulbe any kind of data type,
but it's oriented to numeric string, like
phone numbers.
$Format: should be a conjunction between
numbers (any one) and others caracters.
str_format_number takes each caracter
of $Format, if it isn't a number stores
it to be returned later, but if it is a
number takes the caracter of $String
placed in the position corresponding to
the amount of numbers in $Format so far
starting from zero.
If $Format has less numbers than $string
caracters the rest of the caracters at
the end of $String should be ignored.
If $Format has more numbers than $string
caracters the no caracter will be used,
so those will be ignored.

$string = strrev($string);
$stringLength = strlen($string);
while ($totalLines > $max_lines) {
$pos = 0;
$pos = strpos ( $string, "##") + 2;
//$pos = $pos - $stringLength;

It is also good to use substr() to get a file extension when manipulating with files. For example:
<?php
$dir = "/full/path/to/folder";
if(is_dir($dir))
{
if($dh = opendir($dir))
{
while(($file = readdir($dh)) !== false)
{
if(substr($file,strlen($file)-4,4) == ".txt")
{
echo "Filename: $file<br/>\n";
}
}
closedir($dh);
}
else
{
echo "Cannot open directory";
}
}
else
{
echo "Cannot open directory";
}
?>

//check if we can simply use the built-in functions
if (strpos($str, '&') === false) { //No entities. Use built-in functions
if ($length === NULL)
return substr($str, $start);
else
return substr($str, $start, $length);
}
// create our array of characters and html entities
$chars = preg_split('/(&[^;\s]+;)|/', $str, -1, PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_OFFSET_CAPTURE);
$html_length = count($chars);
// check if we can predict the return value and save some processing time
if (
($html_length === 0) /* input string was empty */ or
($start >= $html_length) /* $start is longer than the input string */ or
(isset($length) and ($length <= -$html_length)) /* all characters would be omitted */
)
return "";
//calculate start position
if ($start >= 0) {
$real_start = $chars[$start][1];
} else { //start'th character from the end of string
$start = max($start,-$html_length);
$real_start = $chars[$html_length+$start][1];
}
if (!isset($length)) // no $length argument passed, return all remaining characters
return substr($str, $real_start);

Regarding windix's function to handle UTF-8 strings: one can use the "u" modifier on the regular expression so that the pattern string is treated as UTF-8 (available from PHP 4.1.0 or greater on Unix and from PHP 4.2.3 on win32). This way the function works for other encodings too (like Greek for example).
The modified function would read like this:
<?php
function utf8_substr($str,$start)
{
preg_match_all("/./u", $str, $ar);
if(func_num_args() >= 3) {
$end = func_get_arg(2);
return join("",array_slice($ar[0],$start,$end));
} else {
return join("",array_slice($ar[0],$start));

Here's a little bit of code to chop strings (with html tags) around a specified length while making sure no html tags are chopped. It also prevents chopping while a tag is still open.
Note: this will only work in xhtml strict/transitional due to the checking of "/>" tags and the requirement of quotations in every value of a tag. It's also only been tested with the presence of br, img, and a tags, but it should work with the presence of any tag.
<?php
function html_substr($posttext, $minimum_length, $length_offset) {
// The approximate length you want the concatenated text to be
$minimum_length = 200;
// The variation in how long the text can be

may be by following functions will be easyer to extract the
needed sub parts from a string:
after ('@', 'biohazard@online.ge');
returns 'online.ge'
from the first occurrence of '@'
before ('@', 'biohazard@online.ge');
returns 'biohazard'
from the first occurrence of '@'
between ('@', '.', 'biohazard@online.ge');
returns 'online'
from the first occurrence of '@'
after_last ('[', 'sin[90]*cos[180]');
returns '180]'
from the last occurrence of '['
before_last ('[', 'sin[90]*cos[180]');
returns 'sin[90]*cos['
from the last occurrence of '['
between_last ('[', ']', 'sin[90]*cos[180]');
returns '180'

If 'start' is negative and greater than the length of the string, PHP seems to return the first 'length' characters of the string. For example, substr('test',-10,1) returns 't'.

* @param string $replacement (default [...])
* @return string
