1.需求
了解parse_url的使用方法
2.实例
$uri = parse_url('http://dummy'.$_SERVER['REQUEST_URI']); var_dump($uri);
array (size=3) 'scheme' => string 'http' (length=4) 'host' => string 'dummy' (length=5) 'path' => string '/test.php' (length=9)
3.手册怎么说
用来分解url的，分成下面几段构造的数组
scheme - e.g. http host port user pass path query - after the question mark ? fragment - after the hashmark #
