good way to go about doing page excerpts

Hi,

I'm looking to achieve the effect facebook has when you put a link into a message - they scrape the title and some images from it. I noticed they also do it extremely quickly. (they must cache some of the re-sent items?)

Does anyone have any ideas on how to approach this with PHP? Can I somehow quickly grab the <title> block of the page without cURLing the entire thing?

Thanks!

You would probably have to grab the entire page and use a HTML DOM parser to rip out the title tag.

Like you said, if you want fast speeds consider caching the results.

thanks, i'm currently using simplehtmldom.. its just too slow!plus PHP runs out of memory doing bigger sites, and I feel that there must be a better solution out there...

I don't know much about cURL, but does it download everything? You could restrict it to just the HTML.

@daniel: SimpleHtmlDom is great, but as you mentioned it's slow. Try using phps DOM class -> http://php.net/manual/en/book.dom.php
