PHP Regex Question

[Drack]

I'm in need of a way to eliminate all non-numeric characters from a string.

Something in PHP that would accomplish this in perl:

$code =~ s/[^0123456789]//;

This is for the ClanOCR database, by the way.

Anyone have any ideas? I don't know how to call a substitution regex in PHP, just match patterns. Perhaps there's some way to loop over the characters in a string and remove any that don't match 0123456789?

I found the solution:

$code = preg_replace('/[^0123456789]/','',$code);
