Ok here you go.

<?php
$all = 'RM50';
// single
$r = 'R';
$m = 'M';
$a = '5';
$b = '0';
$s=strtoHex($all);var_dump($s);
// single
$s=strtoHex($r);var_dump($s);
$s=strtoHex($m);var_dump($s);
$s=strtoHex($a);var_dump($s);
$s=strtoHex($b);var_dump($s);
exit();
exit();

function strToHex($string)
{
    $hex='';
    for ($i=0; $i < strlen($string); $i++)
    {
        $hex .= dechex(ord($string[$i]));
    }
    return $hex;
}
?>

You are welcome.

You'll have to prefix it with \x too (\x[0-9a-f]+ is a hex string in php).

Could probably do it without a loop in php5, like so:

function x($s) {
    return preg_replace_callback('#.#', function($m) {
        return '\x' . dechex(ord($m[0]));
    }, $s);
}

You wouldn't want to add a prefix to all. Only when one \x for all of them as hex.

How do you mean?

\x41\x42\x43 isn't the same as \x414243.

The former will output as 'ABC' (in javascript, PHP doesn't use \x), while the latter will output as 'A4243'. These characters match the expression \x[a-f0-9]{2}, so the numbers following the match won't be taken into account.

You need to stick with one thing. You are jumping all over . The \X is not used in php and therefore if you wanted to prefix the text by a single \X as an informational comment than one\X would have been sufficient.

He was not talking javascript or anything but a simple php routine.

What you coded won't work on half the servers as set up today. I know it won't on mine.

If you wanted to create a separate topic with a complete routine with the complete classes that would be helpful to those who like to learn and have the up to date software capable of using it.

But adding this to a simple question is like giving instructions for wormhole travel to someone asking about the best transportation available in their city today.

I expect this from some of the other posters here to try and show off their skills but expected more from an experienced coder/anaylst.
