如何用PHP分解MYSQL结果

祝大家星期天快乐

只是一个简单的问题：我正在努力以智能的方式查询我的服务器。我想在服务器上查询数据库中最新的新闻文章，并获取标题、内容、日期等

我还想在JQuery选项卡小部件中输出结果，以便用户一次可以看到三个。。。因此，这基本上意味着，在每三个结果之间，我需要输出一个值，以确保JQuery能够适当地提取这些内容

目前我不知道该怎么做。我不知道如何将结果分成单独的组，并在需要的地方插入代码。我试着建立一个阵列。。我试图重置指针/光标等，可惜没有成功。因此，我基本上是多次运行查询（见下文），这显然是一种实现所需结果的非常糟糕的方法。如何更优雅/高效地完成这项工作

谢谢你的帮助

<?php
$con = mysqli_connect('*****','*****','*****','ajax_demo');
if (!$con)
  {
  die('Could not connect: ' . mysqli_error($con));
  }

mysqli_select_db($con,"ajax_demo");
$sql="SELECT * FROM user2 ORDER BY id DESC LIMIT 3";
$sql2= "SELECT * FROM user2 ORDER BY id DESC LIMIT 3,3";
$sql3= "SELECT * FROM user2 ORDER BY id DESC LIMIT 6,3";
$sql4= "SELECT * FROM user2 ORDER BY id DESC LIMIT 9,3";
$sql5= "SELECT * FROM user2 ORDER BY id DESC LIMIT 12,3";

$result = mysqli_query($con,$sql);
$result2 = mysqli_query($con,$sql2);
$result3 = mysqli_query($con,$sql3);
$result4 = mysqli_query($con,$sql4);
$result5 = mysqli_query($con,$sql5);

echo "<div class=\"\" id=\"content1\">\n"; 

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

      {

      echo '<div class="snippet2"><a href="#item'.$row['id'].'">'.$row['Title'] . "</a><br/>";
      echo $row['Date'] . " &nbsp | &nbsp ";

mysqli_close($con);

您只需使用循环中的计数器进行一次查询即可

$ctr=0;
while($row = mysqli_fetch_array($result5)) {

     if($ctr % 3===0){
      /*  do something every third pass*/
     }
      /* increment counter*/
      $ctr++
}

在
内部使用
计数器
，而
ooh就像在VBA中一样：-）让我试试
