如何在PHP中没有GET变量的情况下获取URL的最后一段？

Question

Now I have it like so:

<?
  $url=$_SERVER['REQUEST_URI'];
  $requred_string= substr(strrchr($url, "/"), 1);
?>

and it returns the last segment, but it also returns all the ?p=y&g=x gibberish that I don't need. How can I slice off the $_GET variables?

Answer 1

You can use strtok to exclude the query strings:

$url = strtok($_SERVER['REQUEST_URI'], '?');
$requred_string = substr(strrchr($url, '/'), 1);
echo $requred_string;

Or as mentioned in the comments, parse_url will work also:

$requred_string = substr(strrchr(parse_url($url)['path'], '/'), 1); // PHP 5.4 or greater with dereference

Answer 2

这是一种更优雅的方式basename(parse_url($url, PHP_URL_PATH))
