以编程方式通过URL识别CMS [关闭]

Question

Is there any other way to detect CMS from URL? If yes, is there any available API in PHP o any other language? The site http://whatcms.org/ is an example of what i have in mind; how does it do the detection?

Answer 1

You could check the meta tag for generator. Most CMS have their name and version advertised there.

This is the tag you're after.

<meta name="generator" content="Joomla! - Open Source Content Management" />

This code will try and find the tag to extract the content attribute.

$doc = new DOMDocument();
$doc->loadHTMLFile('http://joomla.org');
$xpath = new DOMXPath($doc);

$generators = $xpath->query('//html/head/meta[@name="generator"]');

echo $generators->item(0)->getAttribute('content');

This code echo's Joomla! - Open Source Content Management
