How to check if the currently logged-in user role matches the given user role?

This small function can be used to match any given user role with the currently logged-in user role in WordPress. For example, if you want to test if the currently logged-in user is a Customer, Subscriber, etc.

function isCurrentUserRole($role){
    $user = wp_get_current_user();
    if ( in_array( $role, (array) $user->roles ) ) {
        return true;
    }
    else{
        return false;
    }
}

Now just pass any user role to this function as a parameter and it will give you the results as true and false. In the following example, I will test if the current user role is equal to the customer or not.

if(isCurrentUserRole('customer')){
    echo 'current user is a customer';
}
else{
    echo 'current user is not a customer'
}
