What is the best way to pass file names and paths to PHP variables from a browser?

When passing file names and paths to PHP variables from a browser, the best way is to use the $_GET or $_POST superglobals to retrieve the values from the URL parameters or form submissions. This ensures that the data is sanitized and prevents security vulnerabilities such as injection attacks. 

// Retrieve file name and path from URL parameters using $_GET
$fileName = isset($_GET['fileName']) ? $_GET['fileName'] : '';
$filePath = isset($_GET['filePath']) ? $_GET['filePath'] : '';

// Sanitize the input if needed
$fileName = filter_var($fileName, FILTER_SANITIZE_STRING);
$filePath = filter_var($filePath, FILTER_SANITIZE_STRING);

// Use the file name and path in your PHP code
echo "File Name: " . $fileName . "<br>";
echo "File Path: " . $filePath;
