You probably don't want the $ after the + sign. This anchors the match to the
end of the string so only illegal characters at the end would be replaced.
Otherwise, the movement of the carat to between the opening square brackets and
adding the commas and replacement string are all on target.
Another important factor is that ereg_replace() returns the altered string
through the function name:
$new = ereg_replace($regex, $replace_with, $old);
so your code should reflect this. The preg* functions work differently.
