努力寻找与此代码的 PHP 7 不兼容

Question

我已经通过 PHP 7 兼容性检查器运行了这段代码，它没有返回任何错误。

但是，当我将服务器从 PHP 5.6 切换到 PHP 7 时，此代码会自动停止工作。它没有输出啤酒水龙头列表，而是什么都不输出。

我在这里缺少什么？显然有什么东西导致它与 PHP 7 中断，我只是无法终生发现它！

代码如下：

<?php

 get_header(); ?>

 <div class="page-container">

    <div class="section">
        <div class="parallax-img" style="background-image: url(<?php the_field('page_banner') ?>);"><h1><?php the_field('page_title') ?></h1></div>
        <div class="section-content">
            <?php the_field('page_content') ?>

                <?php

原来我不得不将我的 php.ini 设置更改为如下所示：

allow_url_fopen = 开启

allow_url_include = 开启
