php获取系统信息的方法
用 getenv函数进行处理:
<?<span php </span><span $root</span> = <span getenv</span>('DOCUMENT_ROOT'); <span //</span><span //服务器文档根目录</span> <span $port</span> = <span getenv</span>('SERVER_PORT'); <span //</span><span //服务器端口</span> <span $file</span> = <span getenv</span>('SCRIPT_NAME'); <span //</span><span //当前执行文件</span> <span $ua</span> = <span getenv</span>('HTTP_USER_AGENT'); <span //</span><span //用户UA</span> <span $method</span> = <span getenv</span>('REQUEST_METHOD'); <span //</span><span //请求方法</span> <span $protocol</span> = <span getenv</span>('SERVER_PROTOCOL'); <span //</span><span //传输协议</span> <span getmypid</span>(), <span //</span><span //返回当前PHP进程的进程ID号,该函数不需要输入参数。</span> <span get_current_user</span>(), <span //</span><span //返回当前程序的所有者名称,该函数也不需要输入参数。</span> ?>
示例:
<?<span php </span><span /*</span><span * * php获取系统信息 * by www.jbxue.com </span><span */</span><span 获取系统类型及版本号: </span><span php_uname</span>() (例:Windows NT COMPUTER 5.1 build 2600<span ) 只获取系统类型: </span><span php_uname</span>('s') (或:<span PHP_OS</span><span ,例:Windows NT) 只获取系统版本号: </span><span php_uname</span>('r') (例:5.1<span ) 获取PHP运行方式: </span><span php_sapi_name</span><span () (PHP run mode:apache2handler) 获取前进程用户名: </span><span Get_Current_User</span><span () 获取PHP版本: </span><span PHP_VERSION</span><span 获取Zend版本: </span><span Zend_Version</span><span () 获取PHP安装路径: </span><span DEFAULT_INCLUDE_PATH</span><span 获取当前文件绝对路径: </span><span __FILE__</span><span 获取Http请求中Host值: </span><span $_SERVER</span>["HTTP_HOST"<span ] (返回值为域名或IP) 获取服务器IP: </span><span GetHostByName</span>(<span $_SERVER</span>['SERVER_NAME'<span ]) 接受请求的服务器IP: </span><span $_SERVER</span>["SERVER_ADDR"] (有时候获取不到,推荐用:<span GetHostByName</span>(<span $_SERVER</span>['SERVER_NAME'<span ])) 获取客户端IP: </span><span $_SERVER</span>['REMOTE_ADDR'<span ] 获取服务器解译引擎: </span><span $_SERVER</span>['SERVER_SOFTWARE'<span ] 获取服务器CPU数量: </span><span $_SERVER</span>['PROCESSOR_IDENTIFIER'<span ] 获取服务器系统目录: </span><span $_SERVER</span>['SystemRoot'<span ] 获取服务器域名: </span><span $_SERVER</span>['SERVER_NAME'] (建议使用:<span $_SERVER</span>["HTTP_HOST"<span ]) 获取用户域名: </span><span $_SERVER</span>['USERDOMAIN'<span ] 获取服务器语言: </span><span $_SERVER</span>['HTTP_ACCEPT_LANGUAGE'<span ] 获取服务器Web端口: </span><span $_SERVER</span>['SERVER_PORT'<span ] </span>?>
