How to process a list of URLs

[koon85]

I have a list of URLs in a text box, each URL in one line of the text box has multiple lines. Now, I want to get the individual URLs and process it until there are no URL left. How can I do it in PHP?

Any suggestions will be appreciate! Thank you very much!

PHP Code:

$urls = explode("\n", $textbox);

foreach ($urls AS $link)
{
    // something
} 


Note that this does not check the validity of the URLs, and assumes that there is only one URL on each line.
