描述
Description
The following code:
<?php declare(strict_types=1);
array_map(trim(...), [1]);
Resulted in this output (on PHP 8.6):
PHP Fatal error: Uncaught TypeError: trim(): Argument #1 ($string) must be of type string, int given in /home/jnoordsij/foo.php:3
Stack trace:
#0 /home/jnoordsij/foo.php(3): trim()
#1 {main}
thrown in /home/jnoordsij/foo.php on line 3
But I expected this output instead (as it is on PHP 8.5):
(Arguably the first outcome may as well be considered correct/preferable, as there is a type error here; then one could consider this a PHP 8.5 and older bug, but fixing that is probably more impactful)
