Issue: https://github.com/php/php-src/issues/8021 Author: PawelBichalski ### Description The following code: ```php <?php error_reporting(E_ALL); $regex = '/^\d+(?:(?:,\d+)+|:\d+)$/'; echo "range 1 - 8192\n"; var_dump(preg_match($regex, implode(',', range(1, 8192)))); echo "range 1 - 8193\n"; var_dump(preg_match($regex, implode(',', range(1, 8193)))); ``` Resulted in this output: ``` range 1 - 8192 int(1) range 1 - 8193 bool(false) ``` But I expected this output instead: ``` range 1 - 8192 int(1) range 1 - 8193 bool(1) or notice message ``` http://sandbox.onlinephpfunctions.com/code/b5a6921f9b5beef87fee5bb6c25a359ba8b76702 ### PHP Version 8.0 ### Operating System _No response_
