You love "5", don't you? :)
I'd probably filter all non-alphanumerics, and then split on any string of letters.
while (<DATA>) {
chomp;
tr/A-Za-z0-9//cd;
my ($number, $extension, $overflow) = split /[A-Za-z]+/;
if ($overflow) {
warn "Don't know how to handle number '$_'.\n";
next;
}
print "Number: $number";
print ", extension: $extension" if defined $extension and length $
+extension;
print "\n";
}
__DATA__
(555) 555-5555
555.555.5555
555-555-5555
(555)555.5555

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
