How can the GD2 Library be activated or installed in XAMPP to resolve the image processing function issue in PHP?

To resolve the image processing function issue in PHP, specifically with the GD2 Library, you need to ensure that the GD extension is enabled in your PHP configuration. This can be done by activating the GD2 Library in XAMPP by uncommenting the "extension=gd" line in the php.ini file. Once the GD extension is enabled, you should be able to use image processing functions in PHP without any issues.

// Check if GD extension is enabled
if (!extension_loaded('gd')) {
    echo 'GD extension is not enabled. Please enable it in your php.ini file.';
} else {
    // GD extension is enabled, you can now use image processing functions
}
