PHP 7.3 Function create_function() is deprecated

Question

I have used create_function in my theme below.

add_action( 'widgets_init', create_function( '', 'register_widget( "Woocommerce_Header_Cart" );' ) );

But for PHP 7.3.0, the create_function() is deprecated.

Any idea, how to fix my codes above on PHP 7.3.0.

Thanks for your help,

Replace

add_action( 'widgets_init', create_function( '', 'register_widget( "Woocommerce_Header_Cart" );' ) );

with this, using an anonymous function instead :

add_action( 'widgets_init', function() { return register_widget("Woocommerce_Header_Cart"); } );
