For starters:

PHP use \ as an escape character for $ inside of ""
Regex uses \ as an escape character for $ as a literal rather than
line-end character.

So your \$ should be \\\$, because PHP will "eat" the \\ and turn that
into \ and then PHP will "eat" the \$ and turn that into $, and then
you'll be passing \$ to Regex.

As it stands now, your Regular expression is:
^$[0-9+...
which is basically an invalid expression, as it has a bunch of crap
trailing after the new-line ($) symbol.

Disclaimer: I'm *NOT* good at Regex.
