This is important as it could be incorrectly evaluated as a successful result if using simple evaluation. For completeness, the return value of NULL on error should be mentioned in the documentation. Test script: --------------- @ $ans == strcmp(array(), $string); $ans now equals a successful hit. (which is wrong, but expected behaviour) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65792&edit=1
