header
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 — Retourne la liste des en-têtes de réponse du script courant
Description
array headers_list
( void
)
headers_list() retourne un tableau avec la liste des en-têtes qui seront transmis au navigateur. Pour déterminer si ces en-têtes ont été déjà envoyés ou pas, utilisez la fonction headers_sent().
Valeurs de retour
Retourne un tableau indexé numériquement d'en-têtes.
Exemples
Exemple #1 Exemple avec headers_list()
<?php
/* setcookie() va ajouter un en-tête */
setcookie('foo', 'bar');
/* Définit un en-tête de réponse
Il sera ignoré par la majorité des navigateurs */
header("X-Sample-Test: foo");
/* Spécification de la réponse en texte simple */
header('Content-type: text/plain');
/* Quels sont les en-têtes qui vont être envoyés ? */
var_dump(headers_list());
?>
L'exemple ci-dessus va afficher :
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
