Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php No, array_keys() isn't doing that. Numeric strings used as an array key are converted to integer when the element is created. This can be seen by removing array_keys() from your code: <?php $a = array('1'=>'abc','a'=>'1'); var_dump($a); ?> And you will see: array(2) { [1]=> string(3) "abc" ["a"]=> string(1) "1" } (Notice no quotes around the integer key.) And NOT: array(2) { ["1"]=> string(3) "abc" ["a"]=> string(1) "1" } Previous Comments: ------------------------------------------------------------------------ [2008-06-24 11:34:28] songqi at baidu dot com Description: ------------ just look at the example Reproduce code: --------------- <?php $a = array('1'=>'abc','a'=>'1'); var_dump(array_keys($a)); ?> Expected result: ---------------- array(2) { [0]=> string(1) "1" [1]=> string(1) "a" } Actual result: -------------- array(2) { [0]=> int(1) [1]=> string(1) "a" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45348&edit=1
