mysql查询结果分组

Question

从 mysql 查询中，我希望将 5 个结果作为一组包装到 li 中。怎样？谢谢，

$counter = 1;
while($row = mysql_fetch_array($result)){
echo '<li>';
if ( ($counter % 5) == 0 ){           
echo '<div class="title">'.$row['title'].'</div>';
}
$counter ++;
echo '</li>';
}
}

我想要一些 html 输出，例如

<li><div class="title">something</div><div class="title">something</div><div class="title">something</div><div class="title">something</div><div class="title">something</div></li>
<li><div class="title">something</div><div class="title">something</div><div class="title">something</div><div class="title">something</div><div class="title">something</div></li>
<li><div class="title">something</div><div class="title">something</div><div class="title">something</div><div class="title">something</div><div class="title">something</div></li>
... <!-- 5 results in one li -->

Answer 1

您需要让 mod % 关闭 li 或打开 li，而不是处理 div。

所以像这样：

$counter = 1;
while($row = mysql_fetch_array($result)) {
    if ( $counter % 5 == 1 ) {           
        echo '<li>';
    }
    echo '<div class="title">'.$row['title'].'</div>';
    if ( $counter % 5 == 0 ) {           
        echo '</li>';
    }
    $counter ++;
}
if ( $counter % 5 != 1 ) {           
    echo '</li>';
}

还没有测试过它，但它应该可以帮助您走上正确的道路。

你们看起来很亲密，怎么样：

$counter = 0;
while($row = mysql_fetch_array($result)){
        if (($counter % 5) == 0) {
            echo '<li>';
        }
        echo '<div class="title">'.$row['title'].'</div>';
        if (($counter % 5) == 4) {
            echo '</li>';
        }
        $counter ++;
    }
}
if ($counter % 5 != 4) {           
    echo '</li>';
}

Answer 3

$x = mysqli_num_rows($result);   
$counter = 0;

while($row = mysql_fetch_array($result)){
if ( ($counter % 5) == 0 ){
echo '<li>'
}           
echo '<div class="title">'.$row['title'].'</div>';
if (((($counter +1) % 5) == 0) || (($counter+1)==$x)){
echo '</li>'
} 
$counter ++;
}

我没有检查它，但 mysqli_num_rows 变量可用于关闭最后一个。
