note 49229 added to function.array-udiff

Very easy way of achieving a case-insensitive version of array_diff (or indeed array_diff_assoc, array_intersect or any of these types of functions which have a similar function that takes a callback function as one of their parameters): array_udiff($array1, $array2, 'strcasecmp'); This works because strcasecmp() compares two strings case-insensitively, as compared to the array_diff() which compares two strings by using the == operator, which is case-sensitive. ---- Manual Page -- http://www.php.net/manual/en/function.array-udiff.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49229 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49229&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49229&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49229&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49229&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49229&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49229&report=yes Search -- http://master.php.net/manage/user-notes.php
