What steps can be taken to ensure compatibility between WordPress plugins and PHP code to avoid errors like the ones described in the forum thread?

To ensure compatibility between WordPress plugins and PHP code, it is important to follow best practices such as using proper naming conventions, avoiding global variables, and properly enqueueing scripts and styles. Additionally, keeping plugins and themes updated to the latest versions can help prevent conflicts and errors.

// Example of properly enqueueing scripts and styles in WordPress
function my_custom_scripts() {
    wp_enqueue_script('my-script', get_template_directory_uri() . '/js/my-script.js', array('jquery'), '1.0', true);
    wp_enqueue_style('my-style', get_template_directory_uri() . '/css/my-style.css', array(), '1.0', 'all');
}
add_action('wp_enqueue_scripts', 'my_custom_scripts');
