Basic email scrubbing script

I am looking just for a basic way to clean up my email list of any email addresses whose users contain ONLY numbers.

Delete any emails like:

I can obviously delete all emails that start with numbers just by alphabetizing the list and deleting 0-9, but that will remove emails like option 2 above.

return trim($s)&!preg_match('#^\d+@#iu',trim($s));
}

$f = file('MyFileName.txt') or die("Error opening file");
print_r(array_filter($f,"bad_emails"));
