How to prevent duplicates within foreach PHP

I'm trying to move customer order notes field to another field group, but because of other plugin overrides, I need to override WooCommerce template files too, so I need to move this code:

foreach ( $checkout->get_checkout_fields( 'order' ) as $key => $field ) :
    woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); 
endforeach;

from: "mytheme/woocommerce/checkout/form-shipping.php"
to: "mytheme/woocommerce/checkout/review-order.php".

Now I'm getting duplicated fields, how to prevent duplicates within foreach loop?

You can maintain an array to keep track of fields you've already seen so that they don't get added again.

$fields_seen = [];
foreach ( $checkout->get_checkout_fields( 'order' ) as $key => $field ) :
    if(!in_array($field, $fields_seen)) {
        woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); 
        $fields_seen[] = $field;
    }
endforeach;

You can use array_unique() your code will look like this:

foreach ( array_unique($checkout->get_checkout_fields( 'order' )) as $key => $field ) :
    woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); 
endforeach;
