Why is it important to use absolute paths when working with files in PHP and how can it prevent errors?

When working with files in PHP, using absolute paths is important because it ensures that the script can reliably locate the file regardless of the current working directory. This helps prevent errors that may occur when the script is executed from different locations or environments. Absolute paths provide a clear and unambiguous reference to the file's location, making the code more robust and easier to maintain.

// Using absolute path to include a file
include_once(__DIR__ . '/path/to/file.php');
