What is the significance of using dirname(__FILE__) in PHP scripts?

Using `dirname(__FILE__)` in PHP scripts is significant because it allows you to get the directory path of the current script file. This is useful when you need to include or require files that are located in the same directory as the current script, without hardcoding the path. It ensures that the paths are always correct regardless of where the script is located in the file system.

// Get the directory path of the current script file
$dir = dirname(__FILE__);

// Include a file located in the same directory
include $dir . '/myfile.php';
