php循环重复执行

Question

我可以在此代码中更改什么以使 This 的输出看起来像 This

两个“This”链接是布局的屏幕截图 我希望所有框都像第二个屏幕截图一样排列/相邻。

我在 html 中编写了布局，并且在尝试 php 时它可以工作，布局只是搞砸了。

function getTest(){

  global $con;

  $get_pro = "select * from drinks";

    $run_pro = mysqli_query($con, $get_pro); 

    while($row=mysqli_fetch_array($run_pro)){

    $id = $row['id'];
    $title = $row['title'];
      $cat = $row['cat'];
      $image = $row['image'];
      $desc = $row['desc'];
      $qty = $row['qty'];
      $price =$row['price'];
      $status= $row['status'];


echo "<!--==========================\n"; 
echo "  Price Menu\n"; 
echo "============================-->\n";

看到你用的是bootstrap，建议你用这种结构

Take a look on this page

<div class="container">
    <div class="row">
        <span class="col-lg-3 col-sm-12 picture">
            <img class="img-thumbnail" src="//placehold.it/200x200">   
        </span>

        <span class="col-lg-3 col-sm-12">
            <img class="img-thumbnail" src="//placehold.it/200x200">   
        </span>

        <span class="col-lg-3 col-sm-12">
            <img class="img-thumbnail" src="//placehold.it/200x200">   
        </span>

        <span class="col-lg-3 col-sm-12">
            <img class="img-thumbnail" src="//placehold.it/200x200">   
        </span>
    </div></div>

从echos 中取出所有的html，然后将PHP 插入到您的html 中。首先，您需要确定需要循环的 html 区域，例如，如果我的原始 html 是这样的：

<div class="row">
    <div class="col-xs-12 col-sm-4">
        Box 1
    </div>
    <div class="col-xs-12 col-sm-4">
        Box 2
    </div>
    <div class="col-xs-12 col-sm-4">
        Box 3
    </div>
</div>

但我想动态生成 3 个框，我的 PHP 会是这样的，你可以将其包装在一个函数中：

<?php
function outputStuff(){

    $contents = array("Box 1","Box 2","Box3");
?>

    <div class="row">

    <?php foreach($contents as $value):?>

        <div class="col-xs-12 col-sm-4">

            <?php echo $value; ?>

        </div>

    <?php endforeach;?>

    </div>

<?php 
} // end the function 
?>

row 必须在循环之外，否则将为每个项目创建它并清除列上的浮动。使用这些基本原则，您将实现您想要的。
