Re: Ensure a number is three digits long

or do something like: function string_to_ascii( $str ) { for( $i=0; $i < strlen( $str ); $i++ ) { $ret = ord( substr( $str, $i ) ); $asc .= (string) ($ret < 10 ? '00' : ($ret < 100 ? '0' : '')) . $ret; } return $asc; } Mike wrote:

You should be able to do this quite well with the str_pad() function. http://us3.php.net/manual/en/function.str-pad.php -M
