What are potential ways to determine the size of a file on a remote server in PHP?

When working with remote servers in PHP, it may be necessary to determine the size of a file stored on the server. One way to achieve this is by using the `filesize()` function in combination with a URL wrapper that supports remote file access, such as `ftp://` or `http://`. By providing the file's URL as an argument to the `filesize()` function, we can retrieve the size of the file on the remote server. 

// Specify the URL of the remote file
$file_url = 'http://example.com/file.txt';

// Get the size of the remote file
$file_size = filesize($file_url);

// Check if the file size retrieval was successful
if($file_size !== false){
    echo "The size of the file is: " . $file_size . " bytes";
} else {
    echo "Failed to get the file size";
}
