示例1: extractInformationFromUrl
/**
* Extracts a keyword from a raw not encoded URL.
* Will only extract keyword if a known search engine has been detected.
* Returns the keyword:
* - in UTF8: automatically converted from other charsets when applicable
* - strtolowered: "QUErY test!" will return "query test!"
* - trimmed: extra spaces before and after are removed
*
* The function returns false when a keyword couldn't be found.
* eg. if the url is "http://www.google.com/partners.html" this will return false,
* as the google keyword parameter couldn't be found.
*
* @see unit tests in /tests/core/Common.test.php
* @param string $referrerUrl URL referrer URL, eg. $_SERVER['HTTP_REFERER']
* @return array|bool false if a keyword couldn't be extracted,
* or array(
* 'name' => 'Google',
* 'keywords' => 'my searched keywords')
