How to put a dollar sign in an Emmet snippet?

Question

Sublime Text

There is this snippet

"snippets": {
  "pre": "echo '<pre>';\nprint_r($expression);\necho '</pre>';"
}

But in reality, the snippet works like this:

echo '<pre>';
print_r(1expression);
echo '</pre>';

That is, he puts a unit instead of a dollar.
Is it possible to do something so that there is still a dollar?
