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;

You should be able to do this quite well with the str_pad() function.

Subject: Ensure a number is three digits long
Hi,
I have am trying to create functions to convert strings to ascii and vice
versa:
function string_to_ascii( $str ) { for( $i=0; $i < strlen( $str ); $i++ ) { $asc .= ord( substr( $str, $i ) ); } return $asc; }
This function works fine, however I need to ensure that the ASCII convertions are three digits long so that I know where to split the ASCII string when converting back to a normal string. i.e. 97 must be 097.
Thanks for any advice offered
