将JSON API作为单个项返回，然后使用PHP排序

Question

我有一个JSON API，可以在自来水中返回有关饮料的数据。我对它进行了编码，以便如果$ days_on返回值为1或更小，它会显示该饮料。可以把它想象成网站的“最近点”部分。现在我想做的是，如果本节中没有显示任何饮料，因为在过去的24小时内没有任何饮料，我想要显示一条消息“对不起最近24小时内没有拍过任何东西”。

我在这里的代码完全忽略了我的比较运算符，并且即使在过去24小时内点击了饮料，也始终显示“抱歉......”消息。

这是似乎有效的代码。你觉得我的方式有什么问题吗？

<?php
$has_tap = false;
$sorry = '<h3>Sorry, nothing new has been tapped in the last 24 hours.<br><a href="/whats-on-tap">Check out our taplist!</a></h3>';

//all that other stuff

($t == $countnumrows ? '' : '');


if ($days_on <= 1) {
$has_tap = true;
echo $html;
}

}

if ($has_tap == false) {
echo $sorry;
}

?>

Answer 1

我不确定你想要实现的目标，但是，

我认为您需要移除break;否则它将在某个时刻退出foreach循环，并且不会遍历整个数组。

试试此代码

<?php
$has_tap = false;
$sorry = '<h3>Sorry, nothing new has been tapped in the last 24 hours.<br><a href="/whats-on-tap">Check out our taplist!</a></h3>';
