Why is it important to ensure the correct installation of libraries like GD-Lib when implementing features like confirmation codes in PHP?

It is important to ensure the correct installation of libraries like GD-Lib when implementing features like confirmation codes in PHP because GD-Lib is a library that provides functions for creating images on the fly, which can be used to generate graphical confirmation codes. Without GD-Lib properly installed, the code for generating confirmation codes may not work as expected or may not work at all. 

// Check if GD-Lib is installed
if (!function_exists('imagecreatetruecolor')) {
    die('GD-Lib is not installed. Please install GD-Lib to generate confirmation codes.');
}

// Code for generating confirmation code using GD-Lib
$confirmationCode = substr(md5(uniqid(mt_rand(), true)), 0, 6);
