What are some best practices for handling multidimensional arrays in PHP, especially when dealing with file uploads?

When handling multidimensional arrays in PHP, especially when dealing with file uploads, it is important to properly iterate through the array elements and handle each file upload individually. This can prevent any unexpected behavior and ensure that each file is processed correctly. 

// Example code snippet for handling multidimensional arrays in PHP with file uploads

if(isset($_FILES['files'])){
    $files = $_FILES['files'];

    foreach($files['name'] as $key => $name){
        $file_name = $files['name'][$key];
        $file_tmp = $files['tmp_name'][$key];
        $file_size = $files['size'][$key];
        $file_error = $files['error'][$key];

        // Handle file upload logic here
        // You can move the file to a specific directory, validate file type, etc.
    }
}
