if (!extension_loaded('gd')) { dl('gd.so'); // Load the gd extension }
extension_dir = "/usr/lib/php/20190902"In this example, we're setting the extension search path to `/usr/lib/php/20190902`. This is where PHP will look for extensions when it tries to load them. Package library: It's difficult to determine the package library from just the examples provided above as they are generic in nature and can be used in various PHP applications. However, package libraries related to PHP Loader config could be PHP Composer, which is a dependency manager for PHP. It allows you to specify the dependencies required for your PHP application and includes a Composer autoloader that handles the automatic loading of these dependencies. Another package library could be PHP Extension and Application Repository (PEAR), which provides a framework and distribution system for reusable PHP components.
