Make a real copy of an array. One simple way is to use array_diff function. <?php // Define a multidimentional array $arr1['color']=array('red','green','blue'); $arr1['number']=array(1,2,3); // Copy all by getting the differance between this and an empty array. $arr2=array_diff($arr1,array()); // To show that its not a reference, delete the original and display the content of the new array. unset($arr1); var_dump($arr2); ?> Output: array(2) { ["color"]=> array(3) { [0]=> string(3) "red" [1]=> string(5) "green" [2]=> string(4) "blue" } ["number"]=> array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } } ---- Server IP: 194.239.128.8 Probable Submitter: 212.242.117.72 ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60954 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60954&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60954&report=yes Search -- http://master.php.net/manage/user-notes.php
