5.2 and 6 are not consistent in many other ways too. 5.3 and 6 OTOH are more consistent, and this is acting same in both. Just don't try comparing 5.2 with anything above.. Previous Comments: ------------------------------------------------------------------------ [2007-12-09 16:25:43] [EMAIL PROTECTED] I'm afraid that is related: http://bugs.php.net/bug.php?id=43231 ------------------------------------------------------------------------ [2007-12-09 14:33:54] dharma dot yp at in dot ibm dot com Description: ------------ In array_walk_recursive(), if we pass non-existent callback function then it gives following output 1)for PHP 5 Warning: array_walk_recursive(): Unable to call echo() - function does not exist in %s on line %d bool(true) 2)for PHP 6 Warning: array_walk_recursive() : Expects parameter 2 to be valid callback, string given in %s on line %d NULL In PHP5, array_walk_recursive() gives warning message the number passed array element times, where as in PHP 6, it gives warning message only once with return value "NULL". This is an inconsistent behavior of array_walk_recursive() with PHP5 and PHP6. The return value of " bool(true)" in PHP5 (1), will misguide/confuse the developers as the documentation says array_walk_recursive() returns TRUE on Success and FALSE on Failure. Reproduce code: --------------- <?php $input = array(array(1,2), array(3), array(4,5)); var_dump( array_walk_recursive($input, 'echo')); ?> Expected result: ---------------- /***** for PHP5 ****/ Warning: array_walk_recursive(): Unable to call echo() - function does not exist in %s on line %d bool(false) /**** for PHP6 ****/ Warning: array_walk_recursive() : Expects parameter 2 to be valid callback, string given in %s on line %d NULL Actual result: -------------- /**** for PHP5 ****/ Warning: array_walk_recursive(): Unable to call echo() - function does not exist in %s on line %d Warning: array_walk_recursive(): Unable to call echo() - function does not exist in %s on line %d Warning: array_walk_recursive(): Unable to call echo() - function does not exist in %s on line %d bool(true) /**** for PHP6 ****/ Warning: array_walk_recursive() : Expects parameter 2 to be valid callback, string given in %s on line %d NULL ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43544&edit=1
