In PHP, what are the differences between using dirname($_SERVER['PHP_SELF']) and explode('/', $_SERVER['PHP_SELF']) to determine the path, and which one is recommended for beginners?

When determining the path in PHP, using dirname($_SERVER['PHP_SELF']) will give you the parent directory of the current script, while explode('/', $_SERVER['PHP_SELF']) will split the path into an array based on the forward slash. For beginners, using dirname($_SERVER['PHP_SELF']) is recommended as it provides a simpler and more straightforward way to get the parent directory of the current script.

// Using dirname($_SERVER['PHP_SELF']) to get the parent directory of the current script
$parentDirectory = dirname($_SERVER['PHP_SELF']);
echo $parentDirectory;
