What is the significance of having a graphic engine installed for PHP scripts?

Having a graphic engine installed for PHP scripts allows for the manipulation and generation of images within the script. This is useful for tasks such as creating dynamic charts, processing and resizing images, and generating thumbnails. By using a graphic engine like GD or Imagick, PHP scripts can easily handle image-related tasks efficiently.

// Check if GD extension is installed
if (!extension_loaded('gd')) {
    echo 'GD extension is not installed. Please install it to enable image manipulation.';
}
