问题：PHP strip_标记&；多维数组形式参数

我在从表单检索的文本输入中剥离标记时遇到问题，以便在

checkout.php

中处理它们。输入存储在

多维数组中

这是我的表格：

  echo '<form name="choose" action="checkout.php" method="post" onsubmit="return  validate_second_form(this);">';

        echo '<input type="hidden" name="hidden_value" value="'.$no_guests.'" />';

        if($no_guests >= 1){

            echo '<div class="volunteer">';
                echo '<fieldset>';
                    echo '<legend>Volunteer:</legend>';
                        echo '<label>Table:</label>';
                        echo '<select name="volunteer_table">';
                            foreach($tables as $t){
                                    echo '<option>'.$t.'</option>';
                                }
                        echo '</select><br><br>';
                        echo '<label>Seat number:</label>';
                        echo '<select name="volunteer_seat">';
                            foreach($seats as $seat){

                                }
                        echo '</select><br><br>';
                        //echo '<br>';

您需要一个

&

来允许编辑对象

foreach ($_POST['guest'] as &$guest)

谢谢你的快速回复。太明显了！

foreach ($_POST['guest'] as &$guest)
