Apache 顯示 PHP 的空白頁面

我已經安裝了新版本Centos 7，我是 Linux 新手。

我使用安裝了 Apache yum -y install httpd，我可以打開測試頁面，一切正常。

之後我使用安裝 PHP(5.4.16)yum -y install php並成功安裝。

之後我使用sudo systemctl restart httpd. 現在我info.php用這段程式碼創建了一個文件：

<php
phpinfo();
?>

當我打開時，http://localhost/info.php我得到一個空白螢幕，裡面什麼都沒有。

我已經閱讀了很多關於此的主題和問題，我做了一切，但沒有任何幫助。

以下是可能對您有所幫助的內容。

Apache 配置文件：庫存文件

php.ini : 庫存文件

.htaccess：沒有文件

您缺少?開始標籤中的 。它應該是：

<?php
phpinfo();
?>

嘗試啟用錯誤報告：

<?php

error_reporting(E_ALL);
phpinfo();

?>
