如何获得两个查询的比率

Question

我有两个不同的查询：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="gallery-container">

  <div class="gallery-column1">
    <div class="content img1">
      <div class="image-overlay">
        <i class="fa fa-search-plus gallery-icon" aria-hidden="true"></i>
      </div>
      <img id="myImg" src="http://elkatesthosting-com.stackstaging.com/mountains/images/gallery1.png">


    </div>

    <div id="myModal" class="modal">
      <span class="close">&times;</span>
      <img class="modal-content" id="img01">
    </div>

    <div class="content img4">
      <div class="image-overlay">
        <i class="fa fa-search-plus gallery-icon2" aria-hidden="true"></i>
      </div>
      <img id="myImg4" src="http://elkatesthosting-com.stackstaging.com/mountains/images/gallery4.png">
    </div>

  </div>


  <div class="gallery-column2">
    <div class="content">
      <div class="image-overlay">
        <i class="fa fa-search-plus gallery-icon3" aria-hidden="true"></i>
      </div>
      <img id="myImg2" src="http://elkatesthosting-com.stackstaging.com/mountains/images/gallery2.png">
    </div>

    <div class="content">
      <div class="image-overlay">
        <i class="fa fa-search-plus gallery-icon4" aria-hidden="true"></i>
      </div>
      <img id="myImg5" src="http://elkatesthosting-com.stackstaging.com/mountains/images/gallery5.png">
    </div>

  </div>

  <div class="gallery-column3">

    <div class="content">
      <div class="image-overlay">
        <i class="fa fa-search-plus gallery-icon5" aria-hidden="true"></i>
      </div>
      <img id="myImg3" src="http://elkatesthosting-com.stackstaging.com/mountains/images/gallery3.png">
    </div>

    <div class="content">
      <div class="image-overlay">
        <i class="fa fa-search-plus gallery-icon6" aria-hidden="true"></i>
      </div>
      <img id="myImg6" src="http://elkatesthosting-com.stackstaging.com/mountains/images/gallery6.png">
    </div>

  </div>

</div>

</div>

如何编写另一个查询以从上述两个查询中获取TotalIDLperday / TotalDLperday的比率？

谢谢

Answer 1

php sql查询作为数组返回。尝试以下操作：

$ratio =  $TotalIDLperdaysql[0]/$TotalDLperdaysql[0];
