getenv函数

php getenv函数



php中getenv()和$_SERVER的用法区别:
getenv 取得系统的环境变量,环境变量的格式为name=value.
语法: string getenv(string varname);
返回值: 字符串 函数种类: PHP 系统功能
内容说明
若正确取得环境变量 varname，则返回变量值。失败则返回 false。
下例可以取得用户浏览器所在机器的网址
$ip = getenv("REMOTE_ADDR");
?>
$_SERVER是服务器超级全局变量数组 用$_SERVER['REMOTE_ADDR']同样可以获取到客户端的IP地址。
二者的区别在于，getenv不支持IIS的isapi方式运行的php
