Question

我有以下PHP代码从特定类别中提取帖子并将其显示在无序列表中。

我想更改此内容，以便在一个<li>中显示5个<ul>，然后为另外5个<ul>创建一个新的<?php $args = array( 'posts_per_page' => 15, 'offset'=> 1, 'category' => $cat_ID ); $myposts = get_posts( $args ); foreach ( $myposts as $post ) : setup_postdata( $post ); ?> <li> <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> </li> <?php endforeach; wp_reset_postdata(); ?>，依此类推。

这是我现有的代码：

    int s = 45;
    double d = *(double *) &s;

Answer 1

另一种方法是使用array_chunk，例如：

$myposts = [1,2,3,4,5,11,22,33,44,55,111,222,333,444];

foreach (array_chunk($myposts, 5) as $posts) {
    echo "<ul>\n";
    foreach ($posts as $post) {
        echo '<li>' . $post. '</li>'. "\n";
    }
    echo "</ul>\n\n";
}

输出：

<ul>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>

<ul>
<li>11</li>
<li>22</li>
<li>33</li>
<li>44</li>
<li>55</li>
</ul>

<ul>
<li>111</li>
<li>222</li>
<li>333</li>
<li>444</li>
</ul>

Answer 2

以下是每5次迭代使用modulus operator的粗略示例。

$myposts = array(1,2,3,4,5,6,7,8,9,10,11);
$output = '<ul>' . "\n";
foreach ($myposts as $count => $post ) {
    if ($count > 1 && $count % 5 == 0 ) {
        $output .= '</ul><ul>' . "\n";
    }
    $output .= '<li>' . $post . '</li>' . "\n" ;
}
rtrim($output, '</ul><ul>' . "\n"); //if it was the tenth iteration we don't want to open another ul
echo $output . '</ul>' . "\n";

输出：

<ul>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul><ul>
<li>6</li>
<li>7</li>
<li>8</li>
<li>9</li>
<li>10</li>
</ul><ul>
<li>11</li>
</ul>

使用PHP将foreach结果拆分为2个无序列表
