This function trims empty strings from the beginning and end of an array. It's useful when outputing plaintext files on a page and you want to skip empty lines at the beginning and end, but not within the text. <?php function array_trim($array) { while (strlen(reset($array)) === 0) { array_shift($array); } while (strlen(end($array)) === 0) { array_pop($array); } return $array; } ?> You might want to trim each element too. --was-- This function trims empty strings from the beginning and end of an array.
