php几个预定义变量$_SERVER用法小结,_server小结

本文实例总结了php几个预定义变量$_SERVER的用法。分享给大家供大家参考。具体如下:

复制代码 代码如下:

echo 'documentroot:'.$_SERVER['DOCUMENT_ROOT'].'
'; //根目录,在apache的配置文件里定义:httpd.conf 比如:DocumentRoot "D:/work/php_root"
echo 'httphost:'.$_SERVER['HTTP_HOST'].'
'; //域名,比如:localhost
echo 'phpself:'.$_SERVER['PHP_SELF'].'
';   // 从根目录到文件本身的路径
echo 'script filename'.$_SERVER['SCRIPT_FILENAME'].'
'; //documentroot+phpself
echo 'request uri'.$_SERVER['REQUEST_URI'].'
'; //从根目录开始所有的URL字符串,包括问号之后的字符
echo 'request method:'.$_SERVER['REQUEST_METHOD'].'
'; //请求的方法
echo 'name:'.$_REQUEST['name'].'
'; //请求参数的值
?>

希望本文所述对大家的PHP程序设计有所帮助。

php 预定义变量要怎输出 比如这个 $_SERVER['SERVER_ADOR']


echo - - 就好~
如果你想看到所有$_SERVER下的变量
echo "

";<br>var_dump($_SERVER);<br>

<p class="ft p1">PHP 提供了大量的预定义变量。由于许多变量依赖于运行的服务器的版本和设置,及其它因素,所以并没有详细的说明文档。一些预定义变量在 PHP 以命令行形式运行时并不生效。常用的预定义数组变量有$_POST,$_GET,$_REQUEST,$_COOKIE,$_SESSION,$_SERVER等,具体你可以参考php手册,上面写的很清楚。<br>
