Question

我正在使用一个简单的PHP脚本来获取我博客的所有文章，并将其显示在带分页的页面上。

我将在我的主页上使用相同的脚本，但是，我想在第一个回显结果之后，在剩余的5个之前放置一个特殊的导航。

这是我正在使用的脚本：

<?php
$posts_sql = "SELECT * FROM publication_posts WHERE section = '".$id."' ORDER BY id DESC LIMIT ".$offset.", ".$display_limit.""; // 6 Posts
$posts_res = mysqli_query($con, $posts_sql);
while($post = mysqli_fetch_assoc($posts_res)){

$post_id = $post["id"];
...

$post_date = date("jS F, Y", strtotime($post_added));

$posts .= "

    <div class=\"post\" id=\"".$post_id."\">
        // Content
    <div class=\"postDivide\"></div>

";
?>
<?php
$navigation = "
// Code for navigation bar
";
?>
<html>
    <?php echo $posts; ?>
</html>

在第一篇文章被回显后，是否可以将$navigation置于$posts内？它是如何完成的？

您是否考虑过这样做？

$posts = fetch_posts(6);

render_post($posts[0]);
render_navigation();
foreach (array_slice($posts, 1) as $post) {
    render_post($posts);
}

<?php

function fetch_posts($section, $start, $num) {
    global $con;
    $posts_sql = "SELECT * FROM publication_posts WHERE section = '".$id."' ORDER BY id DESC LIMIT ".$start.", ".$num."";
    $posts_res = mysqli_query($con, $posts_sql);
    $posts = [];
    while($post = mysqli_fetch_assoc($posts_res)){
        $posts[] = $post;
    }
    return $posts;
}

function render_post($post) {

    $post_id = $post["id"];

    $post_date = date("jS F, Y", strtotime($post_added));

    return "
        <div class=\"post\" id=\"".$post_id."\">
            // Content
        <div class=\"postDivide\"></div>
    ";
}

function render_navigation() {
    return "
        // Code for navigation bar
    ";
}

?>
<html>
    <?php
    $section_id = "??";
    $posts = fetch_posts($section_id, 0, 6);

    echo render_post($posts[0]);
    echo render_navigation();
    foreach (array_slice($posts, 1) as $post) {
        echo render_post($posts);
    }
    ?>
</html>

在特定位置将Elelments添加到PHP循环中
