Answer 1:
您可以使用：
$url = 'http://www.domain.com/River-Island/River-Island-T-Shirt-with-Triangle-Girl-Print/Prod/pgeproduct.aspx?iid=2516020';
$parsed = parse_url($url);
$path = $parsed['path'];
$path_parts = explode('/', $path);
$desired_output = $path_parts[1]; // 1, because the string begins with slash (/)
Answer 2:
$page = explode('/', substr($_SERVER['REQUEST_URI'], 1), 2);
echo str_replace("-"," ", $page[0]);
Answer 3:
尝试这样的： /http:\/\/[^\/]+\/([^\/]+)/i

Answer 4:
$path = parse_url($url, PHP_URL_PATH);
$first = substr($path, 0, strpos($path, '/'));
检查这三个函数的文档。 也许你将不得不从路径的开始剥离斜线，我不知道。
Answer 5:
你用笨... ???那么它可能是
$this->uri->segment(segment number of url);
其需要加载控制器中的URI库
