How can PHP developers improve error reporting and diagnostics for issues related to missing modules in their applications?

When PHP applications encounter issues related to missing modules, developers can improve error reporting and diagnostics by utilizing the PHP function `extension_loaded()` to check for the existence of required modules before attempting to use them. By implementing this check, developers can provide more informative error messages and gracefully handle missing module scenarios. 

if (!extension_loaded('mysqli')) {
    die('The required MySQLi extension is not available. Please install it to continue.');
}
// Proceed with using MySQLi functions
