I generally prefer to use the 'preg' functions, because they more closely
emulate the perl regexp's i first learned -- not sure how this might work
with 'ereg', but the shorthand \w (word character) is equivalent to
[_A-Za-z0-9], and likewise \W is equivalent to anything not in that set.
Other shorthands provided include \s (space character), \S (not a space
character), \d (digit), and \D (not a digit).

So, yours might be rewritten as preg_match('^/[\w\(\) \$-]+$/', $value)
