Question

What is the best way to ascertain the length (in characters) of the longest element in an array?

I need to find the longest element in an array of option values for a select box so that I can set the width dynamically.

Answer 1

This returns the key of the longest value and can also give you the value itself

function array_longest_value( $array, &$val = null ) {     $val = null;     $result = null;      foreach( array_keys( $array ) as $i )     {         $l = strlen( $array[ $i ] );         if ( $l > $result )         {             $result = $i;             $val = $array[ $i ];         }     }      return $result; }
