php echo variable1、pause和echo variable 2然后回显variable1的其余部分 - php echo variable1, pause and echo variable 2 then echo the rest of variable1

php echo variable1, pause and echo variable 2 then echo the rest of variable1

假设我有一个简单的代码：

$sql = dbquery("SELECT * FROM videos WHERE views > 4 ORDER BY id DESC LIMIT 0,10 ");
while($row = mysql_fetch_array($sql)){
  $url = $row["url"];
  $title = $row["title"];
  $list ='<div><a href="'.$url.'" >'.$title.'</a></div>';
  $ad ='<div>something here</div>';
}
echo $list;

相反，为了显示10个div的列表，我想从$list回显5个div，回显$ad，然后回显其余的$list

我该怎么做？

后期编辑：

多亏了迈克尔，第一个问题解决了。

现在，我的模板有问题，我不知道如何添加到$list-dvs的每个X个数字，class="nomar"？

您可以使用计数器$i

$sql = dbquery("SELECT * FROM videos WHERE views > 4 ORDER BY id DESC LIMIT 0,10 ");
$i = 1;
// Use mysql_fetch_assoc() rather than mysql_fetch_array()!
while($row = mysql_fetch_assoc($sql)){
  $url = $row["url"];
  $title = $row["title"];
  // Change the list class on a certain number...
  if ($i == 3) {
     $list_class = "normal";
  }
  else $list_class = "some-other-class";
  // Incorporate the new class
  $list ='<div class="' . $list_class . '"><a href="'.$url.'" >'.$title.'</a></div>';
  // Output $list
  echo $list;    
  // Increment your counter
  $i++;
  // Output $ad when you reach 5
  // This only happens once. Afterward, $list continues to print.
  if ($i == 5) {
    $ad ='<div>something here</div>';
    echo $ad;
  }
}
