Question

我的英语非常糟糕，我在这里感到困惑，有人可以帮助我吗？

我的PHP：

<?php require("db.php"); ?>

<?php //Select All Orders
$stmt = $db->prepare("SELECT * FROM `users`");
$stmt->execute();
$result = $stmt->get_result();
if($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
$counter++;
    if($counter % 2 == 0) {
    echo "<div class='ui stackable six cards'>";
    echo $one[] = "<div class='ui card small'><div class='image'><img src='".$row["avatar"]."'></div>";
    echo $two[] = "<div class='content'><a class='header'>Dias".$row["username"]."</a></div></div>";
    echo "</div>";
  }
  }

}
$stmt->close();
?>

所以我想要做的就是我要拆分的每2行。

所以它看起来像这样：

<div class="ui stackable six cards">

                    <div class="ui card small">
                        <div class="image">
                            <img src="assets/img/players/dias.jpg">
                        </div>

                        <div class="content">
                            <a class="header">Dias</a>
                        </div>
                    </div>

                    <div class="ui card small">
                        <div class="image">
                            <img src="assets/img/players/dias.jpg">
                        </div>

                        <div class="content">
                            <a class="header">Dias</a>
                        </div>

</div>

分离出来的是“<div class="ui stackable six cards">”以及“</div>”

我究竟如何使用我的PHP代码每两行拆分一次？我无法弄清楚

因此，对于它在数据库中找到的每2行，它需要在末尾回显“<div class="ui stackable six cards">”和“</div>”。

这是不可能的吗？它看起来如此

Answer 1

我建议使用切换布尔技术而不是模数条件，因为我发现它更容易阅读。如果结果集中有奇数行，则此方法还将完成外部（分组）div生成。

代码：（Demo）

$resultset=[
    ['avatar'=>1,'username'=>'A'],
    ['avatar'=>2,'username'=>'B'],
    ['avatar'=>3,'username'=>'C'],
    ['avatar'=>4,'username'=>'D'],
    ['avatar'=>5,'username'=>'E'],
    ['avatar'=>6,'username'=>'F']
];
if(sizeof($resultset)){  // your num rows
    $new_group=true;
    foreach($resultset as $row){ // you while loop
        if($new_group){
            echo "<div class='ui stackable six cards'>";  // start new group
        }
        echo "<div class='ui card small'>";
            echo "<div class='ui card small'><div class='image'><img src='".$row["avatar"]."'></div>";
            echo "<div class='content'><a class='header'>Dias".$row["username"]."</a></div></div>";
        echo "</div>";
        if(!$new_group){echo "</div>";}  // end group
        $new_group=!$new_group; // toggle the boolean value
    }
    if(!$new_group){  // if new group is not closed by the "second" member in the group
        echo "</div>";
    }
}

输出：

<div class='ui stackable six cards'>
    <div class='ui card small'>
        <div class='ui card small'><div class='image'><img src='1'></div>
        <div class='content'><a class='header'>DiasA</a></div></div>
    </div>
    <div class='ui card small'>
        <div class='ui card small'><div class='image'><img src='2'></div>
        <div class='content'><a class='header'>DiasB</a></div></div>
    </div>
</div>
<div class='ui stackable six cards'>
    <div class='ui card small'>
        <div class='ui card small'><div class='image'><img src='3'></div>
        <div class='content'><a class='header'>DiasC</a></div></div>
    </div>
    <div class='ui card small'>
        <div class='ui card small'><div class='image'><img src='4'></div>
        <div class='content'><a class='header'>DiasD</a></div></div>
    </div>
</div>
<div class='ui stackable six cards'>
    <div class='ui card small'>
        <div class='ui card small'><div class='image'><img src='5'></div>
        <div class='content'><a class='header'>DiasE</a></div></div>
    </div>
    <div class='ui card small'>
        <div class='ui card small'><div class='image'><img src='6'></div>
        <div class='content'><a class='header'>DiasF</a></div></div>
    </div>
</div>

PHP拆分行？（似乎无法做到）
