Do you want upper case and lower case handled the same, e.g A=1 and a=1? Anyone for PHP Golf?

Here's a starter for 10 - probably a way more efficient way to do it though...
function letters2numbers($s)
{
for($i=0;$i<strlen($s);$i++)
{
if ((96 < ord($s[$i])) && (ord($s[$i]) < 123))
{
$r .= ++$c;
}
else
{
$r .= $s[$i];
$c = 0;
}
}
return $r;
}

- note that this will increase the length of the string if you ever have a sequence of more than 9 characters. Your only alternative would be to wrap back to 0.

I had to do something similar at one point and here is the function I used (had to remove a few things, so it might not work, but should be a good start): function convertLettersToNumbers($myString) { for ($i = 0; $i < strlen($myString); $i++) {
$asciiValue = ord($myString{$i}); if ($asciiValue > 96 && $asciiValue < 123) {
$myString{$i} = $asciiValue - 96;
}
} return $myString;
} You might have to change a few things if your conversion isn't linear (a=1, b=2, etc.) Hope that helps [added: doh! I'm typing too slow!] mavherick
