How can PHP functions be optimized for better performance when working with shortcodes in Wordpress?

When working with shortcodes in Wordpress, PHP functions can be optimized for better performance by minimizing the use of complex logic or heavy operations within the shortcode callback function. Instead, it is recommended to move any heavy processing or database queries outside of the shortcode function and cache the results if possible. This will help reduce the load on the server and improve the overall performance of the shortcode. 

// Example of optimizing PHP functions for better performance with shortcodes in Wordpress

// Define the shortcode callback function
function custom_shortcode_function($atts) {
    // Move heavy processing or database queries outside of the function
    $cached_data = get_transient('custom_shortcode_data');
    
    if (false === $cached_data) {
        // Perform heavy processing or database queries here
        $data = expensive_data_processing_function();
        
        // Cache the results for future use
        set_transient('custom_shortcode_data', $data, 3600); // Cache for 1 hour
    } else {
        $data = $cached_data;
    }
    
    // Return the shortcode output
    return $data;
}

// Register the shortcode
add_shortcode('custom_shortcode', 'custom_shortcode_function');
