我正试图用php-mysqli函数从数据库中获取结果，在那里我可以成功地获取所有结果，但它们都显示在同一行中。如何使它们在显示4个结果后分隔行？
假设我在数据库中总共有8个结果。因此，如果我使用while循环来获取数据并进行回显，它应该是这样的：
data1 data2 data3 data4 data5 data6 data7 data8
但是如何使其显示为这样：
data1 data2 data3 data4
data5 data6 data7 data8
这是示例硬编码div结果：
<div class="row">
<div id="portofolio">
<!-- Project 1-->
<div class="three columns category trains">
<h5>Sponsor 1</h5>
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit.
</p>
<div class="portofoliothumb">

这是我要显示结果的php代码，但我不知道如何用4分隔结果，然后转到下一行进行显示。
此处的PHP代码：
<?php
include 'dbConnection.php';
global $dbLink;
$image = "SELECT * FROM sponsor_item where sponsor_data !='' ";
$result=mysqli_query($dbLink,$image);
// Numeric array
while($row=mysqli_fetch_array($result,MYSQLI_ASSOC)){
?>
<div class="row">
<div id="portofolio">
<!-- Project 1-->
<div class="three columns category trains">
<h5>Sponsor 1</h5>
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit.
</p>
<div class="portofoliothumb">
<img style="margin-left: 0px; margin-top: -218.375px; width: 100%; height: 1150px;" src="data:image/jpeg;base64,<?php echo base64_encode($row['sponsor_data']); ?>" alt="image0<?php echo $row['sponsor_item_id']; ?>">
</div>
</div>
</div>
<?php
}
mysqli_free_result($result);
// Close the mysql connection
$dbLink->close();
?>
您需要添加一个计数器，并查看计数器值何时为4的倍数。如果是这种情况，只需回显DIV结束标记和新的DIV开始标记。您还需要从WHILE循环中排除第一个和最后一个DIV标记：
<?php
include 'dbConnection.php';
global $dbLink;
$image = "SELECT * FROM sponsor_item where sponsor_data !='' ";
$result=mysqli_query($dbLink,$image);
$item = 0;
?>
<div class="row">
<div id="portofolio">
<?php
// Numeric array
while($row=mysqli_fetch_array($result,MYSQLI_ASSOC)){
?>
<!-- Project 1-->
<div class="three columns category trains">
<h5>Sponsor 1</h5>
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit.
</p>
<div class="portofoliothumb">
<img style="margin-left: 0px; margin-top: -218.375px; width: 100%; height: 1150px;" src="data:image/jpeg;base64,<?php echo base64_encode($row['sponsor_data']); ?>" alt="image0<?php echo $row['sponsor_item_id']; ?>">
</div>
</div>
<?php
$item++;
if ($item % 4 == 0) { echo '</div></div><div class="row"><div id="portofolio">'; }
}
mysqli_free_result($result);
// Close the mysql connection
$dbLink->close();
?>
</div>
</div>
计算打印的行数，然后用它在的行数之后插入一行
$counter = 0;
foreach($result as....)
{
print $result->whatever;
$counter++;
if($counter % 4 == 0) // Counter divides cleanly by 4
{
print "<br />";
//Or whatever goes between your rows, eg </div><div class="whatever">
}
}
为此，请使用模数运算符%。这给出了第一个数字除以第二个数字的余数，因此如果该数字干净地除以，则给出0的答案
例如
1 % 4 = 1 // No new line
2 % 4 = 2 // No new line
3 % 4 = 3 // No new line
4 % 4 = 0 // New line!
5 % 4 = 1 // No new line
使用
<?php
$counter=1;
while($row=mysqli_fetch_array($result,MYSQLI_ASSOC)){
{
if($counter%4==0)
{
?>
<div class="row">
<div id="portofolio">
<?php
}
?>
<!--Your Regular repeating DIVS start here-->
<div class="three columns category trains">
<h5>Sponsor 1</h5>
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit.
</p>
<div class="portofoliothumb">
<img style="margin-left: 0px; margin-top: -218.375px; width: 100%; height: 1150px;" src="data:image/jpeg;base64,<?php echo base64_encode($row['sponsor_data']); ?>" alt="image0<?php echo $row['sponsor_item_id']; ?>">
</div>
</div>
<!--Your Regular repeating DIVS end here-->
<?php
if($counter%4==0)
{
?>
</div>
</div>
<?php
}
$count+=1;
}
?>
