Links extraction from a URL

Hi,

I think there's a function in Perl that automatically extracts all links from a given url, but is there a similar type of function for PHP?

For instance, opening the contents of a url is easy with the fopen() function, but I thought there might be an automatic html parser to extract a list of links. Am I too hopeful?

I don't know about a built-in function, but there is an example script at phpfreaks that extracts absolute links from an url. As it is currently written the links are printed and if you click on a link that url is processed and the links extracted. Perhaps you could use it as an example for making your own function.

Thanks RichB, that link was perfect, thanks a ton!

Still need to get my head around regular expressions, but it will come
