Hi,
i made some basic bench and see that it really depends...

It depends on exactly what your doing, how much text you have,
using any of the string functions on the output would ofcourse cause a
performance drawback (do you agree with me?), i had used a combination of
string functions to do instead of regexps, which one will be faster as you
think ?
where can i suggest such a function on the current regexps API ?

(0-9a-zA-Z_) actually. Don't forget that zero and underscore!

here are two regexps that might do what you want
"\w" matches alphanum (1-9a-zA-z)
IMO, the best way to check for non-alphanum chars is
to check for "\W" (upper case is negation of alphanum,
which will match only non-alphanum).
if (preg_match('/^\w+$/', $data)) {
print "entirely alpha
preg_replace will implicitly allow arrays of values for the
search/replace strings.

You could loop it with foreach (which I think is the same way Perl handles
the ex you gave).
foreach ($myArr as $myStr) {
$myStr = ereg_replace($regexp, $myStr);
}
Note quite "one statement", but if you really wanted to shorted it (and in
the opinion of most sacrafice readability), you could
Most of the preg_ functions support arrays of values as input
parameters. It's all in the documentation.

Why don't you do a function with an ereg inside?
I don't think that exist a command like that...
