Pronounced like CMS. This class will scan for known software running on a given website and report it back. Simple to expand, easily to implement. See the file for functions and usage until I can write a better version here.
Example Usage and Output
# Initialize. $seemes = new Seemes(); # Fetch page and spoof as Chrome. $page = $seemes->fetchUrl('http://superfamicom.org/', true); # Set what we want to filter by, nothing for all. $search_for = array(); # Begin the searching... $results = $seemes->checkMetaTags(&$page, $results); $results = $seemes->checkScriptTags(&$page, $results, &$search_for); $results = $seemes->checkPageText(&$page, $results, &$search_for); print_r($results); $analytics = $seemes->getAccounts(&$page); print_r($analytics); Array (  => Reinvigorate  => Google Analytics ) Array (  => Google Analytics: UA-315321-4  => Reinvigorate: n5e27-9j4m6p6586 )
