// the test array $array = array("php", "arrays", "are", "cool");// some variable for testing:$some_var = "NEW";// the function that get"s called for each entryfunction format_array_values(&$item, $key, $some_var) {$item = $some_var . ": $item (KEY: $key)<br/>";}// "walk" trough each array item and call the function:// "format_array_values"array_walk($array, "format_array_values", $some_var);// print the result:print_r($array);/*The output will be:Array([0] => NEW: php (KEY: 0)<br/>[1] => NEW: arrays (KEY: 1)<br/>[2] => NEW: are (KEY: 2)<br/>[3] => NEW: cool (KEY: 3)<br/>)*/
