How can the use of dirname(__FILE__) help in determining the correct file path in PHP?

When working with PHP, determining the correct file path can be crucial for including files, requiring dependencies, or accessing resources. Using the `dirname(__FILE__)` function can help in getting the directory path of the current file, which can then be used to construct the full file path. This method ensures that the file path is accurate regardless of the file's location within the directory structure. 

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

// Construct the full file path by appending the file name
$file_path = $directory . '/filename.php';

// Now $file_path contains the correct file path for further use
