Should $http_response_header be deprecated? #19651
Description
Description
The following code:
<?php
declare(strict_types=1);
error_reporting(-1);
ini_set('display_errors', '1');
echo PHP_VERSION . "<br>\n";
function get_contents() {
file_get_contents("https://www.php.net/manual/en/reserved.variables.httpresponseheader.php");
$headers = $http_response_header;
var_dump($headers);
}
get_contents();Resulted in this output:
8.5.0beta2
array(12) { [0]=> string(15) "HTTP/1.1 200 OK" [1]=> string(17) "Server: myracloud" [2]=> string(35) "Date: Sun, 31 Aug 2025 07:39:53 GMT" [3]=> string(38) "Content-Type: text/html; charset=utf-8" [4]=> string(17) "Connection: close" [5]=> string(20) "Content-language: en" [6]=> string(38) "Permissions-Policy: interest-cohort=()" [7]=> string(27) "X-Frame-Options: SAMEORIGIN" [8]=> string(93) "Link: ; rel=shorturl" [9]=> string(44) "Last-Modified: Sun, 31 Aug 2025 06:00:41 GMT" [10]=> string(38) "Expires: Sun, 31 Aug 2025 07:39:53 GMT" [11]=> string(24) "Cache-Control: max-age=0" }
But I expected this output instead:
8.5.0beta2
Deprecated: The predefined locally scoped $http_response_header variable is deprecated, call http_get_last_response_headers() instead in C:\inetpub\wwwroot\... on line ...

I have been testing PHP 8.5.0beta2 on Windows and have occasionally been getting the message "Deprecated: The predefined locally scoped $http_response_header variable is deprecated, call http_get_last_response_headers() instead in ...". However, I couldn't reproduce it reliably and wrote the small test program above, expecting to get the deprecation message, but didn't.
