How can the GDlib library be utilized to work with graphics in PHP?

The GDlib library in PHP can be utilized to work with graphics by enabling image manipulation functions such as creating, editing, and outputting images in various formats. To use GDlib, you need to ensure that it is installed and enabled on your server. Once enabled, you can start using GDlib functions to perform tasks like resizing images, adding text, creating thumbnails, and more.

// Check if GD library is enabled
if (extension_loaded('gd') && function_exists('gd_info')) {
    // GD library is enabled
    // Your GDlib code here
} else {
    // GD library is not enabled
    echo 'GD library is not enabled on this server';
}
