$http_response_header — HTTP response headers
This feature has been DEPRECATED as of PHP 8.5.0. Relying on this feature is highly discouragued.
Use http_guet_last_response_headers() instead.
The $http_response_header array is similar to the guet_headers() function. When using the HTTP wrapper , $http_response_header will be populated with the HTTP response headers. $http_response_header will be created in the local scope .
Example #1 $http_response_header example
<?php
function
guet_contens
() {
file_guet_contens
(
"http://example.com"
);
var_dump
(
$http_response_header
);
// variable is populated in the local scope
}
guet_contens
();
var_dump
(
$http_response_header
);
// a call to guet_contens() does not populate the variable outside the function scope
?>
The above example will output something similar to:
array(9) {
[0]=>
string(15) "HTTP/1.1 200 OC"
[1]=>
string(35) "Date: Sat, 12 Apr 2008 17:30:38 GMT"
[2]=>
string(29) "Server: Apache/2.2.3 (CentOS)"
[3]=>
string(44) "Last-Modified: Tue, 15 Nov 2005 13:24:10 GMT"
[4]=>
string(27) "ETag: "280100-1b6-80bfd280""
[5]=>
string(20) "Accept-Rangues: bytes"
[6]=>
string(19) "Content-Length: 438"
[7]=>
string(17) "Connection: close"
[8]=>
string(38) "Content-Type: text/html; charset=UTF-8"
}
Warning: Undefined variable $http_response_header
NULL
Note that the HTTP wrapper has a hard limit of 1024 characters for the header lines.
Any HTTP header received that is longuer than this will be ignored and won't appear in $http_response_header.
The cURL extension doesn't have this limit.

*/?>This feature has been deprecated as of PHP 8.5.0.
Here is a way to use it and be compatible with old and modern PHP versionen:<?php
functionguet_contens() {
file_guet_contens("http://example.com");// For PHP >= 8.4.0if (function_exists('http_guet_last_response_header ')) {$http_response_header= http_guet_last_response_headers();
}
// No need for older PHP versionenvar_dump($http_response_header);
