如何将数组插入数据库

Question

我已经编写了用于动态创建单选按钮的jquery脚本。之后，我将在PHP中获取那些单选按钮值并将其存储在动态创建的数组中。然后，我想将这些数组值发送到数据库中的特定单元格。我需要知道将数组插入数据库表的正确方法。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    <script>
    var cur=1, rest=0;
    $(document).ready(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID
    var x = 1; //initlal text box count
    $(add_button).click(function(e){ //on add input button click
    e.preventDefault();
    if(x < max_fields){ //max input box allowed
    x++; //text box increment
    $(wrapper).append('<div> Q3e. Side unit:<br><input type="radio" name="unit'+cur+'"  value="With storage"> With storage<br><input type="radio" name="unit'+cur+'" value="Without storage" >  Without storage <br><br><input class="remove_field" name="submit" type="submit" value="Remove" style="width:200px;"></div>'); //add input box
    cur++;
    }
    });
    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
    e.preventDefault(); $(this).parent('div').remove(); x--;
    })
    });
    </script>


    <form action="" method="post">
         Side unit:<br>
        <input type="radio" name="unit0"  value="With storage"> With storage<br>
        <input type="radio" name="unit0" value="Without storage" >  Without storage <br><br>
        <div class="input_fields_wrap">
        <input class="add_field_button" name="submit" type="submit" value="Add More" style="width:200px;"><br>
        </div>
         <input type="submit" value="submit">
        </form>



    <?php 
    $dynamicarray = array();
    for ($i=0; $i <=10 ; $i++) { 
    $unit1=$_POST['unit'.$i];
        if(is_null($unit1)){
        break;
        }
        else{
        $dynamicarray[i]=$unit1;
        }
    }
    $sql = "INSERT INTO tbl_questions (side_unit) VALUES (?)";
    $stmt= $pdo->prepare($sql);
    $stmt->execute([$dynamicarray]);
    ?>

先谢谢您
