How to obtain the relative path using GET parameters in PHP?

In PHP, you can use the $_GET global variable to retrieve GET parameters. If you want to retrieve relative path parameters, you can pass the relative path as the value of the GET parameter.

For example, suppose there is a URL like http://example.com/index.php?path=relative/path/to/file, you can use the following code to retrieve the relative path parameter:

if(isset($_GET['path'])){
    $relativePath = $_GET['path'];
    // 使用$relativePath进行相对路径的操作
    // ...
}

In the above code, the $_GET[‘path’] retrieves the passed relative path parameter. You can use this relative path parameter to perform corresponding operations based on your needs.

It is important to note that the relative path parameters obtained in this way are treated as strings. If you need to perform operations on the path (such as concatenation, parsing, etc.), you can use PHP’s path handling functions (such as dirname(), basename(), realpath(), etc.) for processing.
