a coleuge gave me the tip to use the function filter_list() to get the possible call back options, but these are also others then used in your example, but in anyway the seams to be shorter and better for memoriziations... <?php print('<pre>'); print_r( filter_list() ); print('<pre>'); ?> example output: Array ( [0] => int [1] => boolean [2] => float [3] => validate_regexp [4] => validate_url [5] => validate_email [6] => validate_ip [7] => string [8] => stripped [9] => encoded [10] => special_chars [11] => unsafe_raw [12] => email [13] => url [14] => number_int [15] => number_float [16] => magic_quotes [17] => callback )
