Question

我一直在研究site。它显示以下错误，

警告：除以零 /home/sunshine/public_html/wp-content/themes/DailyDeal/index.php on 第63行

现在我去检查index.php文件，但是在第63行我只有一个右大括号（}）

如果有人能在这里指出错误（我已经尝试停用所有插件但问题仍然存在），我将非常感激。以下是参考文献

的完整index.php

Answer 1

您的除以零在第61行的包含内。如果您仍然无法找到问题，请发布该代码。

Answer 2

因此，我们在具有数字划分的代码中要非常小心，因为任何数字除以零都是未定义的。在任何设备中尝试 - 您的手机，计算器等。

这个三元条件可能会有所帮助，但是当$ current_price等于0时，不要强制0（零）为$ percentsave的值。这将破坏应用程序的语义逻辑。

    $percentsave = ($current_price != 0) ? $percent/$current_price : 'undefined';

但是，关于你的查询 - 为什么它在第63行显示，也许你有一个代码包装你的IDE（php特定代码），那部分代码可以在第63行看到。

在代码中除以零
