[PHP 8.4] Excluding E_DEPRECATED in error_reporting still shows new deprecation message

[michaljusiega]

Description

The following code:

<?php

declare(strict_types=1);

error_reporting(E_ALL & ~E_DEPRECATED); // same as error_reporting(E_ALL ^ E_DEPRECATED);

function implicitNullable1(string $foo = null) {}
trigger_error('random message1', E_USER_DEPRECATED);

error_reporting(E_ALL & ~E_DEPRECATED & ~E_USER_DEPRECATED); // same as error_reporting(E_ALL ^ E_DEPRECATED ^ E_USER_DEPRECATED);

function implicitNullable2(string $foo = null) {}
trigger_error('random message2', E_USER_DEPRECATED);

Resulted in this output:

Deprecated: implicitNullable1(): Implicitly marking parameter $foo as nullable is deprecated, the explicit nullable type must be used instead in /in/0lbLD on line 7

Deprecated: implicitNullable2(): Implicitly marking parameter $foo as nullable is deprecated, the explicit nullable type must be used instead in /in/0lbLD on line 12

Deprecated: random message1 in /in/0lbLD on line 8

But I expected this output instead:

Deprecated: random message1 in /in/rrMGQ on line 8

Hi team!

After introducing new deprecation in PHP 8.4 https://wiki.php.net/rfc/deprecate-implicitly-nullable-types i receive similar messages on non-user deprecated functions in my project, but I am unable to silence them by using E_ALL & ~E_DEPRECATED bitmask. I think this is a bug. Or I am wrong. Any solution ?

Thanks!

PHP Version

These errors occur when compiling the file, i.e. before the script is actually executed. If you move the function declarations into another file, the warnings will go away. There is no solution, other than splitting the file, or setting the error_reporting level in your php.ini.

@iluuu1994 Yes, you're right. I forgot that Symfony in debug mode resolves all deprecations [ErrorHandler overwrite always by -1).

Thanks!
