How can developers ensure that PHP scripts are optimized for loading external resources asynchronously in WordPress?

To ensure that PHP scripts are optimized for loading external resources asynchronously in WordPress, developers can utilize the wp_enqueue_script() function with the 'async' attribute set to true. This allows the script to load asynchronously, improving page load times and overall performance. 

function load_my_script() {
    wp_enqueue_script( 'my-script', 'https://example.com/script.js', array(), null, true );
}
add_action( 'wp_enqueue_scripts', 'load_my_script' );
