note 58466 added to function.array-intersect

If you store a string of keys in a database field and want to match them to a static array of values, this is a quick way to do it without loops: <? $vals = array("Blue","Green","Pink","Yellow"); $db_field = "0,2,3"; echo implode(", ", array_flip(array_intersect(array_flip($vals), explode(",", $db_field)))); // will output "Blue, Pink, Yellow" ?> ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58466 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58466&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58466&report=yes Search -- http://master.php.net/manage/user-notes.php
