Apache 显示 PHP 的空白页面

Apache 显示 PHP 的空白页面

我安装了新版本Centos 7，我是 Linux 新手。

我使用安装了 Apache yum -y install httpd，可以打开测试页面，一切正常。

之后我使用安装了PHP(5.4.16)yum -y install php并成功安装。

之后我使用 重新启动了 Apache sudo systemctl restart httpd。现在我info.php用以下代码创建了一个文件：

<php
phpinfo();
?>

当我打开时，http://localhost/info.php我看到一个空白屏幕，里面什么也没有。

我已经阅读了很多与此相关的主题和问题，我做了一切，但没有任何帮助。
以下是可能对您有帮助的事情。
