为了更好地理解这个示例,我们始终建议您学习以下列出的 PHP 编程 的基础主题
PHP (PHP: Hypertext Preprocessor 的递归首字母缩写) 是一种广泛使用的开源通用脚本语言,尤其适合 Web 开发,并且可以嵌入到 HTML 中。
下面提到的程序是获取 PHP 当前状态的基本程序。为此,我们使用名为 `phpinfo()` 的内置函数。
phpinfo() - 输出有关 PHP 当前状态的信息,其中包括 PHP 编译选项和扩展、PHP 版本、服务器信息和环境、PHP 环境、操作系统版本信息路径、配置选项的主值和本地值、HTTP 头以及 PHP 许可证。
由于每个系统的设置都不同,`phpinfo()` 通常用于检查给定系统的配置设置和可用预定义变量。
`phpinfo()` 也是一个有价值的调试工具,因为它包含了所有 EGPCS (环境、GET、POST、Cookie、Server) 数据。
步骤 1:使用 phpinfo() 显示版本和配置详细信息。
<?php
phpinfo();
?>
