I am using a convoluted way of extracting URLs from a long string. I've
been using the explode() function multiple times and creating temp
arrays until i explode them down enough to get just the URLs.
I'd rather do it using a regular expression but I am having trouble
finding a good example of this.
Can anyone post a good regular expression to extract the URLS from a
string and save them in an array?
Thanks a lot!

To save matches into an array see http://www.php.net/preg_match_all
(note the $matches parameter). To make a universal url catching regexp
isn't that simple... maybe something along the lines of "http://w+"
but this will fail if you have a sentence that ends with a url (eg.
"Come and read my blog from http://myblog.invalid.")
