How can the $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_FILENAME'] variables be used to obtain file paths in PHP?

To obtain file paths in PHP, you can use the $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_FILENAME'] variables. $_SERVER['PHP_SELF'] returns the filename of the currently executing script, while $_SERVER['SCRIPT_FILENAME'] returns the absolute pathname of the currently executing script. These variables can be useful for obtaining file paths for various purposes in PHP. 

// Using $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_FILENAME'] to obtain file paths
$currentScript = $_SERVER['PHP_SELF'];
$absolutePath = $_SERVER['SCRIPT_FILENAME'];

echo "Current script path: " . $currentScript . "<br>";
echo "Absolute path of script: " . $absolutePath;
