About the windows compat functions below:
I needed fnmatch for a application that had to work on Windows, took a look here and tested both. Jk's works for me, soywiz didn't (on WinXPSP2, PHP 5.2.3).
The only difference between them is addcslashes (soywiz) instead of preg_quote (jk). They _should_ both work, but for some reason soywiz's didn't for me. So YMMV.
However, to make JK's fnmatch() work with the example in the documentation, you also have to strtr the [ and ] in $pattern.
<?php
$pattern = strtr(preg_quote($pattern, '#'), array('\*' => '.*', '\?' => '.', '\[' => '[', '\]' => ']'));
?>
And thanks for the functions, guys.
fnmatch
(PHP 4 >= 4.3.0, PHP 5)
fnmatch — ファイル名がパターンにマッチするか調べる
説明
bool fnmatch
( string $pattern
, string $string
[, int $flags
] )
fnmatch()はstring で指定された文字列が pattern で指定されたシェルワイルドカードにマッチするかどうかチェックします。
パラメータ
- pattern
-
シェルのワイルドカードパターン。
- string
-
調べたい文字列。この機能は特にファイル名のマッチに便利ですが、 通常の文字列に関しても使用できます。
一般的なユーザにとって、シェルパターンやあるいは少なくとも '?'と'*'によるワイルドカードのほうが 慣れていると思われます。そのため、 ereg() または preg_match() などの代わりに fnmatch() をフロントエンドの検索表現として使うことは、 プログラマではないユーザにとってより便利でしょう。
- flags
-
フラグ名については Unix のマニュアル fnmatch(3) も参照ください (そのうちここにも説明が追加されるでしょう)。
返り値
マッチした場合に TRUE、それ以外の場合に FALSE を返します。
例
Example#1 シェルのワイルドカードパターンによる色の名前のチェック
<?php
if (fnmatch("*gr[ae]y", $color)) {
echo "some form of gray ...";
}
?>
注意
警告
今のところ、この機能は Windows あるいは他の POSIX に準拠していないシステムで利用できません。

Possible flags (scratched out of fnmatch.h):
...::...
FNM_PATHNAME:
> Slash in $string only matches slash in $pattern.
FNM_PERIOD:
> Leading period in $string must be exactly matched by period in $pattern.
FNM_NOESCAPE:
> Disable backslash escaping.
FNM_NOSYS:
> Obsolescent.
FNM_FILE_NAME:
> Alias of FNM_PATHNAME.
FNM_LEADING_DIR:
> From fnmatch.h: /* Ignore `/...' after a match. */
FNM_CASEFOLD:
> Caseless match.
Since they’re appearing in file.c, but are not available in PHP, we’ll have to define them ourselves:
<?php
define('FNM_PATHNAME', 1);
define('FNM_PERIOD', 4);
define('FNM_NOESCAPE', 2);
// GNU extensions
define('FNM_FILE_NAME', FNM_PATHNAME);
define('FNM_LEADING_DIR', 8);
define('FNM_CASEFOLD', 16);
?>
I didn’t test any of these except casefold, which worked for me.

soywiz's function still doesn't seem to work -- at least not with PHP 5.2.3 on Windows -- but jk's does.

A revised better alternative for fnmatch on windows. It should work well on PHP >= 4.0.0
<?php
if (!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
return @preg_match(
'/^' . strtr(addcslashes($pattern, '/\\.+^$(){}=!<>|'),
array('*' => '.*', '?' => '.?')) . '$/i', $string
);
}
}
?>

soywiz's function didnt seem to work for me, but this did.
<?php
if(!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
return preg_match("#^".strtr(preg_quote($pattern, '#'), array('\*' => '.*', '\?' => '.'))."$#i", $string);
} // end
} // end if
?>

A better "fnmatch" alternative for windows that converts a fnmatch pattern into a preg one. It should work on PHP >= 4.0.0
<?php
if (!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
return @preg_match('/^' . strtr(addcslashes($pattern, '\\.+^$(){}=!<>|'), array('*' => '.*', '?' => '.?')) . '$/i', $string);
}
}
?>

The last line of soywiz at gmail dot com windows replacement should be changed to:
return preg_match('/' . $npattern . '$/i', $string);
otherwise, a pattern for *.xml will match file.xml~ or any else anything with the text *.xml in it, regardless of position.

A "fnmatch" alternative that converts the pattern, to a valid preg one and uses preg_match then. It will work on windows.
<?php
if (!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
for ($op = 0, $npattern = '', $n = 0, $l = strlen($pattern); $n < $l; $n++) {
switch ($c = $pattern[$n]) {
case '\\':
$npattern .= '\\' . @$pattern[++$n];
break;
case '.': case '+': case '^': case '$': case '(': case ')': case '{': case '}': case '=': case '!': case '<': case '>': case '|':
$npattern .= '\\' . $c;
break;
case '?': case '*':
$npattern .= '.' . $c;
break;
case '[': case ']': default:
$npattern .= $c;
if ($c == '[') {
$op++;
} else if ($c == ']') {
if ($op == 0) return false;
$op--;
}
break;
}
}
if ($op != 0) return false;
return preg_match('/' . $npattern . '/i', $string);
}
}
?>

you couls also try this function that I wrote before I found fnmatch:
function WildToReg($str)
{
$s = "";
for ($i = 0; $i < strlen($str); $i++)
{
$c = $str{$i};
if ($c =='?')
$s .= '.'; // any character
else if ($c == '*')
$s .= '.*'; // 0 or more any characters
else if ($c == '[' || $c == ']')
$s .= $c; // one of characters within []
else
$s .= '\\' . $c;
}
$s = '^' . $s . '$';
//trim redundant ^ or $
//eg ^.*\.txt$ matches exactly the same as \.txt$
if (substr($s,0,3) == "^.*")
$s = substr($s,3);
if (substr($s,-3,3) == ".*$")
$s = substr($s,0,-3);
return $s;
}
if (ereg(WildToReg("*.txt"), $fn))
print "$fn is a text file";
else
print "$fn is not a text file";
