SiteInfo

PHP class that retrieves some basic information from an URL.

##Usage

Create an instance of the class providing an URL as a parameter to the constructor:

$siteInfo = new SiteInfo('https://github.com/koas/SiteInfo');

Now you can call any of these methods:

getTitle()

getDescription()

getKeywords()

getIcon(): retrieves the favicon file URL

getImage(): this method tries some tags (OpenGraph, Twitter Cards, MS tile images, Apple icons) to retrieve a bigger image for the site. If no image is available the favicon image is returned.

If you want to retrieve any other data you can use the generic method getTagValue. For example, let's say you want to retrieve the content of the robots tag. The tag looks like this:

<meta name="robots" content="INDEX,FOLLOW" />

You should call getTagValue like this:

$robotsContent = $siteInfo->getTagValue('meta', 'name', 'robots', 'content');
