Thanks for the fast response.

I did check the migration guide, but for some reason this bit escaped my attention. Guess I need glasses ;-)

Merry Xmas

This is a deliberate change, and already documented in the
migration guide[1] (search for "the @ operator").  It is indeed
not yet documented in the manual proper.

Description:
------------
According to set_error_handler documentation [1],
"current value of error_reporting [...] will be 0 if the statement that caused the error was prepended by the @ error-control operator."

This works as documented with PHP 7.4, but not in 8.0.0 where error_reporting = 4437.

I'm not sure whether this desired behavior or not, but if it is then documentation is incorrect.

[1]: https://www.php.net/manual/en/function.set-error-handler.php


Test script:
---------------
<?php
function error_handler( $p_type, $p_error, $p_file, $p_line ) {
	echo "error_reporting in handler: ", error_reporting(), PHP_EOL;
}
set_error_handler( 'error_handler' );
@date_default_timezone_set('');


Expected result:
----------------
error_reporting = 0

Actual result:
--------------
error_reporting = 4437
(with PHP 7.4, error_reporting = 0 as expected)
