Php grab first image in page

Hey guys I'm wondering how I would be able to grab only the first image on a page. I want 开发者_C百科to echo it somewhere else possibly as a variable.

well I have not attempted this before, but I found a website that looks like it gives a pretty good solution. if you are trying to copy the first image from a URL. http://phpsnips.com/snippet.php?id=61 hope that helps. :)

You use PHP's DOMDocument class to grab the page's source, use an XPath query with DOMDocument to get the first img tag, then grab its src attribute.

You can then use that to save the url, or download the file.
