Description
The following code:
<?php
echo "hello\0world";
✅ Results in this output when executed with php8.3 (also php8.2 and php8.1 and php8.0):
❌ But results in this output when executed with phpdbg8.3 (also phpdbg8.2 and phpdbg8.1):
And I expected this output from phpdbg8.* instead:
❔Interesting thing is that phpdbg8.0 output is correct:
... so the change in behavior seems to be somewhere in between latest 8.0.* and 8.1.
Steps to reproduce with docker
php8.0 ✅
