Woocommerce – How to echo a php code using ob_start in another function?

I’ve tried to copy my php code from foreach loop using ob start but failed. Does anyone knows how to do this? I wanted to add my php code in another function like below.

foreach($kekei as $good => $goodness) { 

                        ob_start();

                        $GLOBALS['myfirstbowanstart'] .= "if ( $packing_fee === 'strtolower(".$goodness['shipping_code'].")' ) {
                        $label = __('Shipping fee');
                        $cost  = ".$goodness['shipping_fee'].";
                        }"; // put here your recursive function name

                        ob_get_clean();

                    }

// Add a custom dynamic packaging fee
add_action( 'woocommerce_cart_calculate_fees', 'add_packaging_fee', 20, 1 );
function add_packaging_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    //$domain      = "woocommerce";
    $packing_fee = WC()->session->get( 'the_chosen_one' ); // Dynamic packing fee


    echo $GLOBALS['myfirstbowanstart'];

/*
    if ( $packing_fee === 'gzeatp1' ) {
        $label = __("Shipping fee");
        $cost  = 3.00;
    } elseif ( $packing_fee === 'box' ) {
        $label = __("Shipping fee");
        $cost  = 9.00;
    }
*/
    if ( isset($cost) )
        $cart->add_fee( $label, $cost );
}

    <?php

    This is the modified code merged with yours, let me know if it works, 

    //Added this block
$packing_fees = array("gzeatp1" => "3.00", "box" => "9.00", "cotton" => "12.00");  //This is for testing purposes

$packing_fee = WC()->session->get( 'the_chosen_one' );  // make this a global variable

$callback =  
    function ($shipping_code, $packing_fee) use ($cost, &$packing_fees)
    {
        if($packing_fee === strtolower($shipping_code)) { 
           $label = __('Shipping fee');
           $cost = $packing_fees[$shipping_code];

           $GLOBALS["myfirstbowanstart"] = array("label" => $label, "cost"=> $cost);
        }
    };


 foreach($kekei as $good => $goodness) { 
   $callback($goodness['shipping_code'], $packing_fee) ;
 } 
/*  //Removed this block
 foreach($kekei as $good => $goodness) { 


                        ob_start();

                        $GLOBALS['myfirstbowanstart'] .= "if ( $packing_fee === 'strtolower(".$goodness['shipping_code'].")' ) {
                        $label = __('Shipping fee');
                        $cost  = ".$goodness['shipping_code'].";
