What is the significance of using an absolute path in the extension_dir configuration for PHP modules?

Using an absolute path in the extension_dir configuration for PHP modules is significant because it ensures that PHP can correctly locate and load the necessary modules. Without an absolute path, PHP may have trouble finding the modules, resulting in errors or failures when trying to use them. By specifying the full path to the directory where the modules are located, PHP can reliably load them every time.

extension_dir = "/full/path/to/modules/directory"
