我是php编码新手。我正在使用以前用.html扩展名保存的网页。为了添加一段php代码，我不得不将其扩展名改为.php。现在，当我运行代码时，它不会显示表格及其在html版本的代码中显示的内容。我不明白我需要做什么修改才能使其完美运行。我的代码编写如下：如何让网页使用php显示所有内容？

你的网络服务器上有PHP安装程序吗？你打电话正确吗？ –
检查您的服务器配置为php –
它显示任何东西吗？如果没有，你会得到一个错误，你的服务器被配置为将它们写入日志文件，而不是将它们输出到浏览器。 [启用错误报告]（http://stackoverflow.com/documentation/php/3339/debugging/11471/displaying-errors#t=201705082209527391933）并让我们知道它说了什么。 – rickdenhaan
