Question

我如何得到当前网址的特定部分？例如，我当前的网址是：

http://something.com/index.php?path=/something1/something2/something3/

好吧，我需要用php打印something2。

谢谢！

Answer 1

您使用PHP中的explode函数将URL与第一个参数（在本例中为正斜杠）分开。要实现您的目标，您可以使用;

$url = "http://something.com/index.php?path=/something1/something2/something3/";
$parts = explode('/', $url);
$value = $parts[count($parts) - 2];

Answer 2

所有这些其他例子似乎都集中在您的确切示例上。我的猜测是你需要一种更灵活的方法来实现这一点，因为如果你的URL发生了变化而你仍然需要从查询字符串中的path参数中获取数据，那么仅爆炸方法非常脆弱。

我会向您指出parse_url()和parse_str()函数。

// your URL string
$url = 'http://something.com/index.php?path=/something1/something2/something3/';

// get the query string (which holds your data)
$query_string = parse_url($url, PHP_URL_QUERY);

// load the parameters in the query string into an array
$param_array = array();
parse_str($query_string, $param_array);

// now you can look in the array to deal with whatever parameter you find useful. In this case 'path'

$path = $param_array['path'];

// now $path holds something like '/something1/something2/something3/'
// you can use explode or whatever else you like to get at this value.
$path_parts = explode('/', trim($path, '/'));

// see the value you are interested in
var_dump($path_parts);

你可以这样做：

$url = explode('/', 'http://something.com/index.php?path=/something1/something2/something3/');
echo $url[5];
