首先在php循环中选择结束很快

Question

不确定为什么但是我做的循环输出每个选择但第一个正确输出。看起来循环在第一次围绕节目的早期结束。    loop ending early循环从第一个选择1获取其信息：。然后做一个ajax调用2：php页面，它将$ days设置为第一个选择选项值。然后循环输出两个选择，直到它等于$ days。 The output showing the other selects working

1：首先选择

 <form>
      <div class="form-group">
    <label for="exampleFormControlSelect1">How many days?</label>
    <select class="form-control" name="days" onchange="Selectdays(this.value);" id="exampleFormControlSelect1" required>
            <option>How many days?</option>
      <option value="1">1 day</option>
      <option value="2">2 days</option>
      <option value="3">3 days</option>
      <option value="4">4 days</option>
      <option value="5">5 days</option>
      <option value="6">6 days</option>
      <option value="7">7 days</option>
      <option value="8">8 days</option>
      <option value="9">9 days</option>      
      <option value="10">10 days</option>
    </select>
  </div>
<div id="days"></div>

2：秒选择循环内部

$count = 0;
echo "<select class='form-control' name='select' id='exampleFormControlSelect1'> ";
while($count != $days) {
    echo "  
     <div class='form-group'>
    <label for='exampleFormControlSelect1'>Date</label>
    <select class='form-control' name='date' id='exampleFormControlSelect1'>
      <option>05/24/2018</option>
      <option>06/2/2018</option>
      <option>07/25/2019</option>
      <option>01/15/2017</option>
      <option>11/5/2018</option>
    </select>
  </div>
  <br>
  <div class='form-group'>
    <label for='exampleFormControlSelect1'>Hours</label>
    <select class='form-control' name='time' id='exampleFormControlSelect1' required>
      <option value=''>How many hours?</option>
      <option>1 hour</option>
      <option>2 hours</option>
      <option>3 hours</option>
      <option>4 hours</option>
      <option>5 hours</option>
      <option>6 hours</option>
      <option>7 hours</option>
      <option>8 hours</option>
    </select>
  </div>";
  $count++;
}
