Actually, implode() will take its arguments in either order, so
there's really only one thing (the comma) which could be causing
the problem.
Also, for the original poster: if you only need to do simple
string replacements, you should see whether str_replace() will
serve your purpose. It's much less expensive than ereg_replace().
If you feel that you require regular expressions, the preg_*()
functions are less expensive than the ereg_*() equivalents.
