#26508 [Bgs]: preg_replace() misbehavior with multidimensional arrays as "subject" paramenter

ID: 26508 User updated by: putaso at nospam dot com Reported By: putaso at nospam dot com Status: Bogus Bug Type: PCRE related Operating System: Windows 2000 PHP Version: 4.3.3 New Comment: Shouldn't it be more clear in the manual? anyways.. i don't think you should get "Array" and "object" strings then if now multidimensional arrays are supported. Should I create a new bug as a Documentation Bug, or something like that? thanks to you for taking the time for replying. Previous Comments: ------------------------------------------------------------------------ [2003-12-03 09:11:33] derick@php.net 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 preg_replace doesn\'t do multidimensional arrays so arays get converted to \"Array\" and objects to \"Object\". ------------------------------------------------------------------------ [2003-12-03 09:04:18] putaso at nospam dot com Description: ------------ <?php /* preg_replace() misbehavior. Treats Multidimensinal arrays in "subject" in a really weird way. */ class object {}; $alpha = new object; $alpha->beta = "alpha-beta"; $alpha->gama->x = "hola"; $array = array("a" => "abc", "azw", array("a", "b", array("af")), $alpha->beta, $alpha->gama ); print_r (preg_replace("/[a|e|i|o|u]/", "#", $array)); /* and this is what i get: Array ( [a] => #bc [0] => #zw [1] => Arr#y [2] => #lph#-b#t# [3] => Obj#ct ) Is is correct that i get an array element called "Arr#y" and Obj#ct?? shouldn't preg_replace go through the arrays recursively? The manual is not very clear about that: "If subject is an array, then the search and replace is performed on every entry of subject , and the return value is an array as well." anyways... I don't think that if the function finds an array or an object, treats it as string "Array" and string "Object", */ ?> Reproduce code: --------------- <?php class object {}; $alpha = new object; $alpha->beta = "alpha-beta"; $alpha->gama->x = "hola"; $array = array("a" => "abc", "azw", array("a", "b", array("af")), $alpha->beta, $alpha->gama ); print_r (preg_replace("/[a|e|i|o|u]/", "#", $array)); ?> Expected result: ---------------- Array ( [a] => #bc [0] => #zw [1] => Array ( [0] => # [1] => b [2] => Array ( [0] => #f ) ) [2] => #lph#-b#t# [3] => stdClass Object ( [x] => hol# ) ) Actual result: -------------- Array ( [a] => #bc [0] => #zw [1] => Arr#y [2] => #lph#-b#t# [3] => Obj#ct ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26508&edit=1
