can it be because I'm using it in a PHP file like this?

Yes, you have to escape each backslash for use with `echo'. A simple test
(with php -a) shows that
<?php
echo <<<HTML
var q = '\\a';
HTML;
?>
displays only one backslash.
The simple and most efficient solution is to take heed of this general
advice: Do not let the PHP parser do things it does not have to.
<?php
...
?>
var q = '\\a';
<?php
...
?>
(The first and last part are optional, of course.)
