note 17619 added to function.strcmp

Determines the string which is in common for all variables in the passed array. Can be used to remove complete references from an array filled with file locations. This one goes from left to right, but it can easily be changed into the opposite if desired. <?php function strComp($array) { while (!$quit) { $offset++; $srchChr = substr($array[0],0,$offset); for ($i = 0; $i < sizeof($array); $i++) { if (substr($array[$i],0,$offset) != $srchChr) { $quit = true; } } } return substr($srchChr,0,strLen($srchChr)-1); } $array[] = "My name is Tom"; $array[] = "My name is Sam"; $array[] = "My name is Ted"; $array[] = "My name is Sal"; echo strComp($array); ?> -- http://www.php.net/manual/en/function.strcmp.php http://master.php.net/manage/user-notes.php?action=edit+17619 http://master.php.net/manage/user-notes.php?action=delete+17619 http://master.php.net/manage/user-notes.php?action=reject+17619
