How can developers troubleshoot and address issues related to script loading speed and efficiency in PHP when using WordPress?

To troubleshoot and address issues related to script loading speed and efficiency in PHP when using WordPress, developers can utilize techniques such as minifying scripts, combining multiple scripts into one file, and utilizing asynchronous loading for non-essential scripts. Additionally, optimizing database queries and reducing the number of plugins can also improve script loading speed. 

// Example of minifying and combining scripts in WordPress functions.php file
function custom_theme_scripts() {
    wp_enqueue_script('combined-scripts', get_template_directory_uri() . '/js/combined-scripts.min.js', array('jquery'), null, true);
}
add_action('wp_enqueue_scripts', 'custom_theme_scripts');
