Note, that array_combine converts string keys in exactly the same way as the operator [] does (i.e. "10" -> 10 etc.). IMHO array_combine should not skip keys with other types than string or int but convert them to a string or an int. Thus array_combine should behave like [] operator. Moreover, the PHP_Compat package does it so but there is another bug there: if illegal key is found (e.g. an array) a warning is reported instead of skipping such key (@ is missing there). Reproduce code: --------------- $a = array("0",0,"-10",-10,null,5.4,array(1,2,3),false); $b = array(1,2,3,4,5,6,7,8); var_dump(array_combine($a,$b)); Expected result: ---------------- array(4) { [0]=> int(8) [-10]=> int(4) [""]=> int(5) [5]=> int(6) } Actual result: -------------- array(2) { [0]=> int(2) [-10]=> int(4) } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29008&edit=1
