How can PHP beginners automate the process of obtaining the absolute path to a file without including the filename, especially when passing the system to non-programmers?

PHP beginners can automate the process of obtaining the absolute path to a file without including the filename by using the `__DIR__` magic constant, which represents the directory of the current file. By concatenating `__DIR__` with the relative path to the file, beginners can easily get the absolute path. This method is simple and does not require advanced knowledge of PHP.

$absolutePath = __DIR__ . '/path/to/directory/';
