>A key that is present in both $array1 and $array2 is showing up in the output. Of course it does. You're comparing array1 to array3 and array2 to array3. Previous Comments: ------------------------------------------------------------------------ [2006-05-24 05:06:11] lig at maolek dot com Description: ------------ unexpected output. Accourding to docs array_diff_ukey "returns an array containing all the values of array1 that have keys that are not present in any of the other arguments". A key that is present in both $array1 and $array2 is showing up in the output. It should be noted that the values of the keys are different, but the example provided in the doc page has the same situation and the key isn't in the output. Reproduce code: --------------- function key_compare_func($a, $b) { if ($a === $b) { return 0; } return ($a > $b)? 1:-1; } $array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red", ""); $array2 = array("a" => "green", "yellow", "red", TRUE); $array3 = array("red", "a"=>"brown", ""); $result[] = array_diff_ukey($array1, $array3, "key_compare_func"); $result[] = array_diff_ukey($array2, $array3, "key_compare_func"); print_r($result); Expected result: ---------------- Array ( [0] => Array ( [b] => brown [c] => blue ) [1] => Array ( [2] => 1 ) ) Actual result: -------------- Array ( [0] => Array ( [a] => green [b] => brown [c] => blue ) [1] => Array ( [a] => green [2] => 1 ) ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37573&edit=1
