In PHP 4.0.4+, backreferences are of the form \\n and $n ..  The
problem arises because of the $n notation in the replacement
string....  I've done a fair bit of digging and it doesn't look like
there's a way to disable the replacement.  The only thing I can think
to do would be to prepend any $'s with a double backslash via another
preg_replace prior to this one...

This seems to work :

$v = preg_replace('/(\$[0-9])/', '\\\\$1', $v);

Kinda the same thing as what I have, just in reverse.. :)
