I have a bunch of strings that may or may not have a substring similar to the following:
<a class="tag" href="http://www.yahoo.com/5"> blah blah ...</a>
Im trying to retrieve the ‘5’ at the end of the link (that isnt necessarily a one digit number, it can be huge). But, this string will vary. The text before the link, and after, will always be different. The only thing that will be the same is the <a class="tag" href="http://www.yahoo.com/ and the closing </a>.
You can do it using
preg_match_alland<a class="tag" href="http:\/\/(.*)\/(\d+)">regular expression.
