Well, a slash has a special meaning inside PHP strings, more so for
double quoted strings. Are you correctly escaping the slash as a double
slash so that it's not interpreted by the string as an escaped
character, as you will need to as the preg_replace will be interpreting
it as an escape sequence to match?
