我有这段代码
while ($row = mysqli_fetch_array ($r, MYSQLI_ASSOC)) {
echo "
<div><h4><a href=\"page.php?id={$row['subcategory_id']}\">{$row['subcategory']}</a></h4>
</div>\n";
}
有了这个,我在页面上放了一个带有子类别的垂直线。例如:
foo
foo
foo
foo
foo
foo
foo
我想将这些子类别限制为10,并在每个10之后再次从顶部开始,如下所示:
foo foo foo
foo foo foo
foo foo foo
foo foo foo
foo foo foo
foo foo foo
foo foo foo
有人可以告诉你怎么做吗?

以下是一个有效的例子:https://3v4l.org/MmWJA
以下是使用您自己的代码的示例:
// get your array in a var
$array = mysqli_fetch_all($r, MYSQLI_ASSOC);
// set column to 10 items tall
$col_height = 10;
// count the array
$count = count($array);
// determine number of columns based on column height and array size
$row_len = $count / $col_height;
//create iterator
$i = 0;
// loop that shits
foreach($array as $row) {
// added display = inline
echo "<div style='display:inline-block;'><h4><a href=\"page.php?id={$row['subcategory_id']}\">{$row['subcategory']}</a></h4></div>\n";
// echo a line break only when needed, reset the iterator
if($i == $row_len){
echo "<br>";
$i = 0;
}
}
