Extracting URLs from a string using a Regular Expression - PHP Development

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! Erin G...

    Default Extracting URLs from a string using a Regular Expression

    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.")
