Gmagick::borderimage method in PHP is used to add a border around the image. It takes four parameters:

1. $color: The color of the border, specified as a string.
2. $width: The width of the border.
3. $height: The height of the border.
4. $method: Specify the method to apply the border. The available options are "constant", "tile", "mirror", and "transparent".

Here's an example of how to use Gmagick::borderimage:

php
$image = new Gmagick('path/to/image.jpg'); // Load the image

$color = 'black'; // Border color
$width = 10; // Border width
$height = 10; // Border height
$method = 'constant'; // Border method

$image->borderimage($color, $width, $height, $method); // Add border to the image

$image->writeImage('path/to/output.jpg'); // Save the modified image

$image->destroy(); // Clean up resources


In this example, the Gmagick class is used to load an image from a file. Then, the borderimage method is called to add a black border of 10 pixels width and height to the image using the "constant" method. Finally, the modified image is saved to a new file, and the resources are cleaned up.

You can customize the values of $color, $width, $height, and $method according to your requirements.
