Description
Description
Logs created by PHP's error_log INI setting have the correct mode but the error_log() function appears to ignore the error_log_mode setting. I've tried setting error_log_mode using ini_set() and as a PHP-FPM php_admin_value.
The following code:
<?php
ini_set('error_log_mode', '0o200');
error_log('Something went wrong', 3, 'exceptions.log');
Resulted in this output:
-rw-r--r--. 1 apache apache 20 Nov 24 23:07 exceptions.log
But I expected this output instead:
--w-------. 1 apache apache 20 Nov 24 23:07 exceptions.log
PHP Version
PHP 8.2.13

Research direction
Start by reproducing the PHP 8.2.13 example with error_log_mode set through ini_set() and error_log() writing to exceptions.log. Trace the error_log handling in php-src and verify that the configured mode affects files created with message type 3, including a regression test for the reported permissions.
