从动态表单向数据库插入数据数组

Question

i have a dynamic form. in form i can add multiple field as much as I want. but I am confused how to save it into the database.

this my form code, just like this but little diferent https://jsfiddle.net/Twisty/q8zj00s0/1/

   <form id="tambahepisode" method="post" style="margin-bottom: 20px;"></form>
<form>
  <ul id="fieldList">
    <li>
      <input name="name[]" type="text" placeholder="Name" form="tambahepisode"/>
    </li>
    <li>
      <input name="phone[]" type="text" placeholder="Phone" form="tambahepisode"/>
    </li>
    <li>
      <input name="email[]" type="text" placeholder="E-Mail" form="tambahepisode"/>
    </li>
  </ul>
  <button id="addMore">Add more fields</button>
  <br>
  <br>
  <input type="submit" name="submit" class="btn btn-default" value="Publikasi" form="tambahepisode" style="width: 100%;" />
</form>

and here my jquery to create dynamic form

<script type="text/javascript">
    $(function() {
  $("#addMore").click(function(e) {
    e.preventDefault();
    $("#fieldList").append("<li>&nbsp;</li>");
    $("#fieldList").append("<li><input type='text' name='name[]' placeholder='Name' /></li>");
    $("#fieldList").append("<li><input type='text' name='phone[]' placeholder='Phone' /></li>");
    $("#fieldList").append("<li><input type='text' name='email[]' placeholder='E-Mail' /></li>");
  });
});

</script>

my basic insert to database

if(isset($_POST['submit'])){
        $name= htmlentities($_POST['name']);
        $phone= htmlentities($_POST['phone']);
        $email= htmlentities($_POST['email']);
        $query = $db->prepare("INSERT INTO `data`(`name`,`phone`,`email`)
        VALUES (:name,:phone,:email)");
        $query->bindParam(":name", $name);
        $query->bindParam(":phone", $phone);
        $query->bindParam(":email", $email);
        $query->execute();
        header("location: index.php");
    }

At first you have to count how much no of record you want to save, as you want save array by add more button.

For example count name or any other field.

$count = count($_POST['name']);

Then use foreach or for loop.

for($i=0;$i<$count;$i++){
    $name= htmlentities($_POST['name'][$i]);
    $phone= htmlentities($_POST['phone'][$i]);
    $email= htmlentities($_POST['email'][$i]);
    $query = $db->prepare("INSERT INTO `data`(`name`,`phone`,`email`)
        VALUES (:name,:phone,:email)");
    $query->execute();        
}
header("location: index.php");
