I'm currently trying to inline css with a html content which works perfect but only once. When I try it multiple times I'm getting this error:

PHP Fatal error: Cannot declare class Emogrifier, because the name is
already in use

The error is thrown in the email-functions.php wich gets included in my Wordpress child theme functions.php file:

/**
 * Include email functions for ultimate member
 */
require 'ultimate-member/functions/email-functions.php';

This is the function in the email-functions.php file which causes the problem:

/**
 * Apply css to UM email message from template
 */
add_filter( 'um_email_send_message_content', 'apply_style_to_email', 10, 99);
function apply_style_to_email($message, $slug, $args ) 

 //Get Emogrifier class
 include_once get_home_path() . 'wp-content/themes/DiviChild/ultimate-member/libraries/class-emogrifier.php';

 ob_start();
 include_once get_home_path() . 'wp-content/themes/DiviChild/woocommerce/emails/email-styles.php';
 $css = apply_filters( 'woocommerce_email_styles', ob_get_clean() );

 // apply CSS styles inline for picky email clients.
 try 
 $emogrifier = new Emogrifier( $message, $css );
 $message = $emogrifier->emogrify();
 catch ( Exception $e ) 
 $logger = wc_get_logger();
 $logger->error( $e->getMessage(), array( 'source' => 'emogrifier' ) );
 

 return $message;

As you can see I'm using include_once to get the Emogrifier class. I really don't know what I'm doing wrong here.

This is the Emogrifier class: https://codeshare.io/50B0ml

The error describes your problem quite well. It looks like there are 2 classes with the same name in your project. Here a NameSpace could help you.

It's best to search your project files for the keyword "emogrifier", maybe you have the class 2 times in the project. Or the class comes from one of the vendor directories via Composer, but that should not happen with the Composer Packages NameSpaces.

You probably need to use require_once(), which does exactly what it says.

If you require() a file that has already been required, PHP doesn't care: it reads the source-file again, leading to this error. Whereas, require_once() will read the source-file only if it hasn't already been read before.
