I think it should not return true. Test script: --------------- <? var_dump(0 == 'e'); // true ?> Expected result: ---------------- bool(false) Actual result: -------------- bool(true) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54625&edit=1
