Question: 1 / 400

What constant in PHP returns the current working directory?

__PATH__

__DIR__

The constant that returns the current working directory in PHP is indeed the built-in function getcwd(). However, it's important to clarify the roles of the options.

While __DIR__ is a magic constant that returns the directory of the file where it is used, it does not necessarily represent the current working directory of the executing script. Instead, it gives the path of the file itself, which can be different from the actual working directory.

In contrast, getcwd() is a function that specifically retrieves the current working directory and is the correct choice when you're looking for the directory in which the PHP script is currently executing. It is able to reflect changes made to the current working directory during the script's runtime, while __DIR__ remains static based on the file context.

Hence, getcwd() is the accurate method to obtain the current working directory, providing the expected functionality in PHP when dealing with directory management.
