I don't know. I just got that from reading the manual. The very first
user comment on the preg_match page.

If you want to use some of PHP's special characters in your expression,
such as $, you must escape it twice. For example:
$matchme = "\$example";
if (preg_match("/\$example/", $matchme)) {
will not be matched because PHP interprets the \$ and passes it as $.
Instead, you must do this:
if (preg_match("/\\\$example/", $matchme)) {

Don't forget to check the manual.
