如何在斜线后取一个字符串？

Question

像：

"http://www.blog-name.com/search/taio cruz"

---------------------------------------------^
 "Sorry, no posts were found with the
tag taio cruz"

问题：

如果用户输入http://www.blog-name.com/search/taio cruz，浏览器会查找名为“taio cruz”的文件夹，不是吗？

如何获得“Taio Cruz”的价值？

Answer 1

echo basename("http://www.blog-name.com/search/taio cruz"); //taio cruz

Answer 2

$url = 'http://www.blog-name.com/search/taio cruz';
$val = end(explode('/', $url));
// $val is now 'taio cruz'

Answer 3

$url = 'http://www.blog-name.com/search/taio cruz';
$last = substr($url, strrpos($url, '/') + 1);
//$last is now "taio cruz"
