How can PHP beginners determine the absolute path of a script on the server for file transfer operations?

PHP beginners can determine the absolute path of a script on the server by using the `__FILE__` magic constant in combination with the `dirname()` function. This will give them the full path to the current script, which can then be used for file transfer operations.

// Get the absolute path of the current script
$absolute_path = dirname(__FILE__);

// Use $absolute_path for file transfer operations
