[php-src] Issue #10513: Spaceship operator fails on long strings

Issue: https://github.com/php/php-src/issues/10513 Author: TomHAnderson ### Description The following code: ```php <?php ``` $hashA = '00000000000007e60000000000000000'; $hashB = '00000000000053110000000000000000'; for ($i = 15; $i <= 16; $i ++) { $subA = substr($hashA, 0, $i); $subB = substr($hashB, 0, $i); echo $subA . "\n"; echo $subB . "\n"; $spaceship = $subA <=> $subB; if ($spaceship > 0) { echo ('Non-equal strings do not return -1 for spaceship operator: ' . $subA . ' ' . $subB . "\n"); } $strcasecmp = strcmp($subA, $subB); if ($strcasecmp > 0) { echo ('Non-equal strings do not return -1 for strcasecmp: ' . $subA . ' ' . $subB . "\n"); } echo "\n"; } Resulted in this output: ``` 00000000000007e 000000000000531 00000000000007e6 0000000000005311 Non-equal strings do not return -1 for spaceship operator: 00000000000007e6 0000000000005311 ``` But I expected this output instead: ``` 00000000000007e 000000000000531 00000000000007e6 0000000000005311 ``` ### PHP Version PHP 8.1.14 ### Operating System Mac OS
