php - PHP删除foreach中的条件

问题描述

我正在尝试编辑一个对来自平台的流进行排序的 WordPress 插件。

我只想显示来自 ID 的任何流。

这是页面控制器的链接（引导程序）

<?php
$streamHeading = get_option('pixiehuge-stream-heading', 'Our streams');
$streamsection = get_option('pixiehuge-stream-section-enable');

$streams = pixiehuge_streams();
global $sectionNum;
?>

<?php if($streamsection && !empty($streams)): ?>
    <section id="streams"<?php echo (!empty($sectionNum) && $sectionNum == 1) ? ' class="firstWithBg"' : '' ?>>
        <?php
        $sList = [
            'twitch' => pixiehuge_streams(false, 'twitch'),
            'youtube' => pixiehuge_streams(false, 'youtube'),
            'mixer' => pixiehuge_streams(false, 'mixer'),
        ];
        $active = false;
        ?>
        <div class="container">

            <!-- /CONTAINER -->

<?php endif; ?>

我不喜欢 PHP 对象，所以我很迷茫。我知道我必须删除$sList第 12 > 16 行，因为我不想从 Youtube 中对其进行排序...

但是后来我不知道如何编辑 foreach 第 51 行foreach($sList as $id => $items)来做一个没有条件的 foreach 元素 ID。只是表中任何元素的 foreach。

我试图从头开始： 第 51 行

<div class="tab-content content">

    <?php foreach($stream as $streams){ ?>
        <p><?php echo $stream['title']; ?></p>
    <?php } ?>

</div>

但它没有用......而且我不能告诉你错误

编辑

这是有效的，但我不能通过 ID DESC 订购它并将其限制为 4 个结果......

            <div class="tab-content content">
                <?php foreach($streams as $key => $stream): ?>
                    <p><?php echo $stream['title']; ?></p>
                <?php endforeach; ?>
            </div>

谢谢您的帮助
