Hello every body

$field = $_POST;          // all the POST fields

$filtered = filter($field);

function filter($array){
     $search_for = "what you want to filter by";
     $i=1;
     $output = array();

     foreach($array as $array_value){
          if(eregi($search_for,$array_value)){
               $output['value'.$i] = $array_value;
          }
          $i++;
     }
     return $output;
}

havent tested it, but it should work.

I would probably tweak that code:

     foreach($array as $key => $array_value){
          if(eregi($search_for,$array_value)){
               $output[$key] = $array_value;
          }
     }

That way the returned filtered array has the same keys as the source.
