php scripts to get meta data from an outside ajax request

In general the consumer needs to send a post request with an action and url. This is usually done in JSON but isn't required.

• 'title' - The script will respond back, in JSON (watch for quotes) with the html <title> of the url you sent.
• 'descritption' - The script will respond back, in JSON (watch for quotes) with the meta tag labeled as name='description' at the url you sent.
• 'ogdescription' - The script will respond back, in JSON (watch for quotes) with the meta tag labeled as property='og:description' at the url you sent

• og:description (or the Open Graph description) is the description offered to facebook etc. See this page for more info on the open graph protocol.
• The 'description' action will fall back to an open graph description if it finds one and doesn't find a traditional description. (probably rare). Currently 'ogdescription' does not to the reverse. Let me know if it should...
