Php Help needed...

Can someone share some code that will grab from a webpage all a href's and img's on the page? Also how to grab a certain text string out of a webpage.

Thanks

I'll be nice and share one regexp :)

This grabs all linked images on a page:

PHP Code:


		
			
/<a.*href=[\"|\']([^\"|^\'|^\s]+)[\"|\'].*><img.*src=[\"|\']([^\"|^\'|^\s]+)[\"|\'].*><\/a>/im

In PHP, do it like this:

PHP Code:


		
			
preg_match_all("/<a.*href=[\"|\']([^\"|^\'|^\s]+)[\"|\'].*><img.*src=[\"|\']([^\"|^\'|^\s]+)[\"|\'].*><\/a>/im", $string, $matches)

$matches is an array with all of the images with links. Just change up the regexp for plain links, images, etc.

Thanks, but is your top link correct? It looks like it is cutoff?
