What are the potential ways to access the source code of a different frame using PHP?

To access the source code of a different frame using PHP, you can use the file_get_contents() function to retrieve the content of the desired file. You will need to provide the file path or URL of the file you want to access. Make sure you have the necessary permissions to access the file.

$source_code = file_get_contents('path/to/other/frame/file.php');
echo $source_code;
