How to use a variable in php from one function to another?

Question

WordPress

It is necessary to remove the payment method if the order amount is less than 1000 rubles, write the following code:

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

$limit_reached = false;

function wc_minimum_order_amount() 
{
  // Задать переменную, чтобы указать минимальное значение заказа
  $minimum = 1000;
  
  if ( WC()->cart->total < $minimum ) {
    $limit_reached = true;
    
  }
  return $limit_reached;
}

function unsetting_payment_gateways( $available_gateways ) 
{	
  if ($limit_reached) {			
      // Здесь установить способ оплаты
      unset($available_gateways['cod']);
  }
  
  return $available_gateways;
}
add_action('woocommerce_available_payment_gateways', 'unsetting_payment_gateways');

But unfortunately it doesn't work, and the functions work separately
There is an opinion that the $limit_reached variable from the wc_minimum_order_amount function is not passed to the unsetting_payment_gateways function, please help

Answer 1

Make the variable global, or pass it as an argument to the second function..
