The following code:
<?phpecho"hello\0world";
✅ Results in this output when executed withphp8.3 (alsophp8.2 andphp8.1 andphp8.0):
helloworld❌ But results in this output when executed withphpdbg8.3 (alsophpdbg8.2 andphpdbg8.1):
helloAnd I expected this output fromphpdbg8.* instead:
helloworld❔Interesting thing is thatphpdbg8.0 output is correct:
helloworld... so the change in behavior seems to be somewhere in between latest8.0.* and8.1.
Steps to reproduce with docker
php8.0 ✅
