note 94381 deleted from ref.array by levim

Note Submitter: shadiadiph at yahoo dot com ---- This is a useful function to remove an array value from an array. <?php function rem_array($array,$str){ foreach ($array as $key => $value) { if ($array[$key] == "$str") unset($array[$key]); } return $array; } $selected=''; $selected ="three"; $numbers=array(); $numbers=array('one','two','three','four'); print_r($numbers); // returns Array ( [0] => one [1] => two [2] => three [3] => four ) // now we are going to call the function to see if the number three the $selected number is in the array $numbers and remove it. $numbers = rem_array($numbers,$selected); print_r ($numbers); // returns Array ( [0] => one [1] => two [3] => four ) ?> I am finding it usefull for drop down lists on forms where you do not want the selected value duplicated.
