PHP pathinfo 被查询字符串中的 url 欺骗了，有什么解决方法吗？
我正在开发一个小函数来接收 url 并根据其所在位置返回相对路径。
如果 url 在查询字符串中包含路径，则 pathinfo 返回不正确的结果。下面的代码证明了这一点：
$p = 'http://localhost/demos/image_editor/dir_adjuster.php?u=http://localhost/demos/some/dir/afile.txt';
$my_path_info = pathinfo($p);
echo $p . '<br/><pre>';
print_r($my_path_info);
echo '</pre>';
该代码输出：
http://localhost/demos/image_editor/dir_adjuster.php?u=http://localhost/demos/some/dir/afile.txt
Array
(
[dirname] => http://localhost/demos/image_editor/dir_adjuster.php?u=http://localhost/demos/some/dir
[basename] => afile.txt
[extension] => txt
[filename] => afile
)
这显然是错误的。有什么解决办法吗？
I am working on a small function to take in a url and return a relative path based on where it resides itself.
If the url contains a path in the query string, pathinfo returns incorrect results. This is demonstrated by the code below:
$p = 'http://localhost/demos/image_editor/dir_adjuster.php?u=http://localhost/demos/some/dir/afile.txt';
$my_path_info = pathinfo($p);
echo $p . '<br/><pre>';
print_r($my_path_info);
echo '</pre>';
That code outputs:
http://localhost/demos/image_editor/dir_adjuster.php?u=http://localhost/demos/some/dir/afile.txt
Array
(
[dirname] => http://localhost/demos/image_editor/dir_adjuster.php?u=http://localhost/demos/some/dir
[basename] => afile.txt
[extension] => txt
[filename] => afile
)
Which obviously is wrong. Any workaround?

是的，这样做正确；）
对于 URL，尤其是带有查询字符串的 URL，
parse_url()应该更可靠地提取路径组件；之后，对其运行pathinfo()。Yeah, doing it right ;)
and for URLs, especially those with query strings,
parse_url()should be more reliable to extract the path component; After that, run thepathinfo()on it.
