headers_list

Returns a list of response headers sent (or ready to send) (PHP 5)
array headers_list ( )

headers_list() will return a list of headers to be sent to the browser / client. To determine whether or not these headers have been sent yet, use headers_sent().

Return Values

Returns a numerically indexed array of headers.

Examples

Example 1602. Examples using headers_list()

copy to clipboard

<?php

/* setcookie() will add a response header on its own */
setcookie('foo', 'bar');

/* Define a custom response header

   This will be ignored by most clients */
header("X-Sample-Test: foo");

/* Specify plain text content in our response */
header('Content-type: text/plain');

/* What headers are going to be sent? */
var_dump(headers_list());

?>

The above example will output:

copy to clipboard

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); } } $Array = get_headers("php.net", "/"); // print_r(get_headers("php.net", "/")); echo " \n"; foreach ($Array as $Key => $Value) { echo "<LI>\$_SERVER[\"$Key\"]=$Value\n"; if ($Key == 6) $Cookie = $Value; } # End of foreach ($_SERVER as $Key=>$Value) echo " \n"; echo "Cookie = $Cookie \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

I don't know if there is already a function for this or not, but I wrote one anyways. <?PHP function headers_array() { $return = array(); $headers = headers_list(); foreach($headers as $header) { if(strpos($header,':') === false) $return[0] = $header; else { $parsed = explode(':',$header,2); $return[$parsed[0]] = trim($parsed[1]); } } return $return; } var_dump(headers_array()); ?> yeilds: array(5) { ["X-Powered-By"]=> string(9) "PHP/5.2.4" ["Expires"]=> string(29) "Thu, 19 Nov 1981 08:52:00 GMT" ["Cache-Control"]=> string(62) "no-store, no-cache, must-revalidate, post-check=0, pre-check=0" ["Pragma"]=> string(8) "no-cache" ["Content-type"]=> string(9) "text/html" }

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 ( [0] => HTTP/1.1 200 OK [1] => Date: Sat, 02 Sep 2006 13:47:02 GMT [2] => Server: Apache/1.3.37 (Unix) PHP/5.2.0-dev [3] => X-Powered-By: PHP/5.2.0-dev [4] => Last-Modified: Sat, 02 Sep 2006 13:21:09 GMT [5] => Content-language: en [6] => Set-Cookie: COUNTRY=USA%2C68.37.136.230; expires=Sat, 09-Sep-2006 13:47:02 GMT; path=/; domain=.php.net [7] => Connection: close [8] => Content-Type: text/html; charset=utf-8 )
