将通过POST提交的变量附加到先前通过PHP在POST中提交的字符串中？

Question

所以，我的情况如下。我有比萨饼有价格，用户可以选择披萨应该有的尺寸（第1页）。当用户选择提交的尺寸（以及披萨的名称）时，在下一页上，用户可以根据尺寸选择浇头＃。 2表示小型，3表示大型等（第2页）。由于用户可以但不一定必须选择最大量的浇头，因此我在保持数据分开方面存在问题。

我基本上想要区分为每个披萨选择的配料。目前我得到array(1) { ["toppings"]=> array(5) { [0]=> string(3) "Egg" [1]=> string(6) "Rucola" [2]=> string(6) "Rucola" [3]=> string(5) "Bacon" [4]=> string(10) "Mozzarella" } }

我想要一个包含披萨名称，大小，topping1，topping2，topping3，下一个披萨，大小，topping1，topping2，topping3的字符串。

由于

public function arrayIterator($pizzen) {
    $html_table = "";

    foreach($pizzen as $key) {
        $html_table .= '<tr>';
        foreach ($key as $value) {
            if(is_numeric($value)) {
                $html_table .= '<td>' . sprintf('%01.2f', $value) . '</td>';
            } else {
                $html_table .= '<td>' . $value . '</td>';
                $checkboxValue = $value;
            }
        }
        $html_table .= '<td><select class="selectpicker" name="size[]"><option></option><option name="small" value="' . $checkboxValue . ' small">Small</option>
