Unexpected? change in debug_backtrace for closures #16729
Description
Description
The following code:
$callers = \debug_backtrace();
// build cache key
$id = \sprintf('%s::%s', $callers[1]['class'], $callers[1]['function']);
var_dump($callers[1]['class']);
var_dump($callers[1]['function']);
exit;Can also be reproduced with:
git clone git@github.com:sulu/sulu.git sulu
cd sulu
composer update --ignore-platform-reqs
php@8.4 vendor/bin/phpunit --filter="MemoizeTest::testMemoizeFirstCall"
Resulted in this output (PHP 8.4):
string(43) "Sulu\Component\Cache\Tests\Unit\MemoizeTest"
string(80) "{closure:Sulu\Component\Cache\Tests\Unit\MemoizeTest::testMemoizeFirstCall():53}"
But I expected this output instead (PHP 8.3):
string(43) "Sulu\Component\Cache\Tests\Unit\MemoizeTest"
string(41) "Sulu\Component\Cache\Tests\Unit\{closure}"
Is this change expected when upgrading from PHP 8.3 to 8.4? I'm fine with the change but wanted to report its an unexpected change.

Yes, Closures got renamed to provide more information about their identity. That's intentional.

See: #13550.
