To: leo at leoberkhout dot nl,
in PHP 5.0 get_headers() already exists so when i went through your code and organized it i had a small problem with that. Other than that when i changed the function name it worked fine. Of course i did tweak a few minor things to make it so. But this is what i've got.
<?php
function gimme_headers($host,$url) {
$headers = array();
$fp = fsockopen ($host,80,$errno,$errstr,45);
if($fp) {
fputs($fp,"GET $url HTTP/1.0\r\n\r\n");
while(!feof($fp)) {
$char = fgetc($fp);
if($char === "\n") {
if(ord($header) === 13) {
return($headers);
}
else {
array_push($headers,trim($header));
}
unset($header);
}
else {
$header = $header . $char;
}
}
fclose ($fp);
}
}
if(isset($_GET['uri'])) {
$uri = $_GET['uri'];
}
else {
$uri = 'php.net';
}
$array = gimme_headers($uri, "/");
print 'Cookie list for ' . $uri;
print '<ul>';
foreach ($array as $key => $value) {
print '<li>' . $_SERVER[$key] . ' = ' . $value . '</li>';
}
print '</ul>';
?>
headers_list
(PHP 5)
headers_list — 送信した (もしくは送信される予定の) レスポンスヘッダの一覧を返す
説明
array headers_list
( void
)
headers_list() はブラウザもしくはクライアントに送信されるヘッダの数値配列を返します。 これらのヘッダが送信されたかどうかを判断するためには headers_sent() を使用します。
返り値
ヘッダを、数値添字の配列で返します。
例
例1 headers_list() の使用例
<?php
/* setcookie() でレスポンスヘッダをそれ自身に追加します */
setcookie('foo', 'bar');
/* 独自のレスポンスヘッダを定義します。
これはほとんどのクライアントで無視されます */
header("X-Sample-Test: foo");
/* レスポンスがプレーンテキストだと宣言します */
header('Content-type: text/plain');
/* 送信しようとしているヘッダは? */
var_dump(headers_list());
?>
上の例の出力は以下となります。
array(4) { [0]=> string(23) "X-Powered-By: PHP/5.1.3" [1]=> string(19) "Set-Cookie: foo=bar" [2]=> string(18) "X-Sample-Test: foo" [3]=> string(24) "Content-type: text/plain" }

If I change in de above code "php.net" for antoher URL, de code doesn't work properly.
How can it be made in a way like this:
http://webtools.live2support.com/header.php
I spent a hole evening, but I found only a way to make the output more readable:
<?php
function get_headers($host, $url)
{
$headers = array();
$fp = fsockopen ($host, 80, $errno, $errstr, 45);
if ($fp)
{
fputs ($fp, "GET $url HTTP/1.0\r\n\r\n");
while (!feof($fp))
{
$char = fgetc($fp);
if($char === "\n")
{
if (ord($header) === 13) { return($headers); }
else { array_push($headers, trim($header)); }
unset($header);
}
else { $header = $header.$char; }
}
fclose ($fp);
}
}
$Array = get_headers("php.net", "/");
// print_r(get_headers("php.net", "/"));
echo "<P>\n";
foreach ($Array as $Key => $Value)
{
echo "<LI>\$_SERVER[\"$Key\"]=$Value\n";
if ($Key == 6)
$Cookie = $Value;
} # End of foreach ($_SERVER as $Key=>$Value)
echo "<P>\n";
echo "Cookie = $Cookie<BR>\n";
?>
Here I do a check with, for example, key 6, to seperated them from the other values, just for example.
My problem is that the code does not accept www.mysite.com or http://www.mysite.com

Also note that Lukes code could be simplified if using the HTTP HEAD method, because it returns only the HTTP headers, not the whole resource.

I arrived here looking for a way to collect headers sent by a remote server. No such luck; so:
<?php
function get_headers($host, $url)
{
$headers = array();
$fp = fsockopen ($host, 80, $errno, $errstr, 45);
if ($fp)
{
fputs ($fp, "GET $url HTTP/1.0\r\n\r\n");
while (!feof($fp))
{
$char = fgetc($fp);
if($char === "\n")
{
if (ord($header) === 13) { return($headers); }
else { array_push($headers, trim($header)); }
unset($header);
}
else { $header = $header.$char; }
}
fclose ($fp);
}
}
?>
print_r(get_headers("php.net", "/"));
Array
