unfortunately the documentation, while telling one how to use
preg_replace, does not tell how to write a regular expression.

In this case google is not my friend as the tutorial I read
suggested (as _I_ read it):

$contact = preg_replace("[0-9\-]*","",$contact);

when I want to return a string that contains only numbers or the
hyphen (a telephone number in the US).

preg_replace does not like the * which the tutorial says means
"do it over and over"

and $contact = preg_replace("[0-9\-]","",$contact);
doesn not modify the string at all.

a bit of help (or a lot of help) would be appreciated (no, I have
not been in school for quite some time, Jerry)
