我已经编写了两个列布局的CSS,我有一个"用户"带有用户注释的数据库。
所以当我像这样运行一个while循环时: while($ row = mysqli_fetch_array($ result))
PHP应该像这样动态创建html(取决于用户数量):
<div class="row">
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
<!-- Notes of user 1 -->
</div>
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
<!-- Notes of user 2 -->
</div>
</div>
<div class="row">
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
<!-- Notes of user 3 -->
</div>
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
<!-- Notes of user 4 -->
</div>
</div>
如果只有一个用户,html应该是这样的:
<div class="row">
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
<!-- Notes of user 1 -->
</div>
</div>
同样,如果有3个用户,则应该有一行有两列,另一行有一列。
有没有办法做到这一点?
编辑:在这里添加了我的PHP代码。
<?php
$query = "SELECT * FROM users";
$result = mysqli_query($conn, $query);
while($row = mysqli_fetch_array($result)){
?>
<div class="row">
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
</div>
</div>
<?php } ?>
该代码存在的问题是它使用&#34;一列&#34;创建了一个新行。为每个用户。我的目标是拥有两列#34;在行中。

你可以用循环中的模运算符(%)来实现类似的东西。
$i = 0;
$rowCount = mysqli_num_rows($result);
$rowsHTML = '';
while($row = mysqli_fetch_array($result)){
$notesHTML = '<div class="col">
<div class="col-content">'.$row['notes'].'</div>
<!-- Notes of user 1 -->
</div>';
if($i%2 == 0){
$notesHTML = '<div class="row">'.$notesHTML;
// check if its the last item and the row has to be closed after 1 col
if($i+1 == $rowCount){
$notesHTML = $notesHTML.'</div>';
}
} else {
$notesHTML = $notesHTML.'</div>';
}
$rowsHTML .= $notesHTML;
$i++;
}
echo $rowsHTML;

<?php
$query = "SELECT * FROM users";
$result = mysqli_query($conn, $query);
$i = 0;
?>
<div class="row">
<?php
while($row = mysqli_fetch_array($result)){
if($i>1 && $i%2==0) echo '</div><div class="row">';
$i++;
?>
<div class="col">
<div class="col-content"><?php echo $row['notes'] ?></div>
</div>
<?php } ?>
</div>
