[php-src] Issue #18948: Missing deprecation notice for allow_url_include

Issue: https://github.com/php/php-src/issues/18948 Author: kkmuffme ### Description https://wiki.php.net/rfc/deprecations_php_7_4#allow_url_include >Proposal: Add a deprecation notice if allow_url_include=1 **on startup**. When changing this ini value with ini_set, there should be a deprecation notice too? Looks like it's possibly only reported on startup? The following code: ```php <?php ini_set('allow_url_include', 1); ``` Resulted in this output: ``` ``` But I expected this output instead: Deprecation notice ### PHP Version ```plain PHP 8.4 ``` ### Operating System _No response_
