Only if you put '0' and '1' as strings it behaves correctly. Test script: --------------- if (in_array("a", array(0, 1) )===true){ echo "'a' is inside array(0,1)"; } else { echo "'a' is NOT inside array(0,1)"; } Expected result: ---------------- 'a' is NOT inside array(0,1) Actual result: -------------- 'a' is inside array(0,1) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70466&edit=1
