SERVER["HTTP_ACCEPT"]=*/*
$_SERVER["HTTP_REFERER"]=http://localhost/lianxi/
$_SERVER["HTTP_ACCEPT_LANGUAGE"]=zh-cn
$_SERVER["HTTP_ACCEPT_ENCODING"]=gzip, deflate
$_SERVER["HTTP_USER_AGENT"]=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

$_SERVER["HTTP_CONNECTION"]=Keep-Alive
$_SERVER["PATH"]=C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem;C:Program FilesCommon FilesAdobeAGL;C:Program FilesMySQLMySQL Server 5.0bin;C:php;C:phpext
$_SERVER["SystemRoot"]=C:WINDOWS
$_SERVER["COMSPEC"]=C:WINDOWSsystem32cmd.exe
$_SERVER["PATHEXT"]=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
$_SERVER["WINDIR"]=C:WINDOWS
$_SERVER["SERVER_SIGNATURE"]=
Apache/2.0.55 (Win32) PHP/5.1.1 Server at localhost Port 80 \使用的何服务器
$_SERVER["SERVER_SOFTWARE"]=Apache/2.0.55 (Win32) PHP/5.1.1
$_SERVER["SERVER_NAME"]=localhost \服务器名称
$_SERVER["SERVER_ADDR"]=127.0.0.1
$_SERVER["SERVER_PORT"]=80 \服务器端口
$_SERVER["REMOTE_ADDR"]=127.0.0.1
$_SERVER["DOCUMENT_ROOT"]=D:/lianxi \网站的主目录
$_SERVER["SERVER_ADMIN"]=sss@163.com \安装APACHE时设置的邮箱
$_SERVER["SCRIPT_FILENAME"]=D:/lianxi/lianxi/servervalues.php \当前的网页的绝对路径,
$_SERVER["REMOTE_PORT"]=1076 \远程端口
$_SERVER["GATEWAY_INTERFACE"]=CGI/1.1
$_SERVER["SERVER_PROTOCOL"]=HTTP/1.1
$_SERVER["REQUEST_METHOD"]=GET
$_SERVER["QUERY_STRING"]=\获取?号后面的内容
$_SERVER["REQUEST_URI"]=例子:/lianxi/servervalues.php?a=1&b=2
$_SERVER["SCRIPT_NAME"]=例子:/lianxi/servervalues.php
$_SERVER["PHP_SELF"]=/lianxi/servervalues.php \返回当前网页的相对路径.
$_SERVER["REQUEST_TIME"]=1179190013 \运行时间 单位为十万分之一毫秒
$_SERVER["argv"]=Array
$_SERVER["argc"]=0
说明:返回此结果运行的网站的主目录是D:/lianxi
foreach($_SERVER as $asd =>$values)
{
echo("$_SERVER["$asd"]=".$values."");
}
$_SERVER存储当前服务器信息,其中有几个值 如$_SERVER["QUERY_STRING"],$_SERVER["REQUEST_URI"],$_SERVER["SCRIPT_NAME"] 和$_SERVER["PHP_SELF"]常常容易混淆,以下通过实例详解$_SERVER函数中 QUERY_STRING,REQUEST_URI,SCRIPT_NAME和PHP_SELF变量区别,掌握这四者之间的关系,便于在实际应用中正确获 取所需要的值,供参考。
1,$_SERVER["QUERY_STRING"]
说明:查询(query)的字符串
2,$_SERVER["REQUEST_URI"]
说明:访问此页面所需的URI
3,$_SERVER["SCRIPT_NAME"]
说明:包含当前脚本的路径
4,$_SERVER["PHP_SELF"]
说明:当前正在执行脚本的文件名
实例:
1,http://www.biuuu.com/ (直接打开主页)
结果:
$_SERVER["QUERY_STRING"] = “”
$_SERVER["REQUEST_URI"] = “/”
$_SERVER["SCRIPT_NAME"] = “/index.php”
$_SERVER["PHP_SELF"] = “/index.php”
2,http://www.biuuu.com/?p=222 (附带查询)
结果:
$_SERVER["QUERY_STRING"] = “p=222″
$_SERVER["REQUEST_URI"] = “/?p=222″
$_SERVER["SCRIPT_NAME"] = “/index.php”
$_SERVER["PHP_SELF"] = “/index.php”
3,http://www.biuuu.com/index.php?p=222&q=biuuu
结果:
$_SERVER["QUERY_STRING"] = “p=222&q=biuuu”
$_SERVER["REQUEST_URI"] = “/index.php?p=222&q=biuuu”
$_SERVER["SCRIPT_NAME"] = “/index.php”
$_SERVER["PHP_SELF"] = “/index.php”
$_SERVER["QUERY_STRING"]获取查询语句,实例中可知,获取的是?后面的值
$_SERVER["REQUEST_URI"] 获取http://www.biuuu.com后面的值,包括/
$_SERVER["SCRIPT_NAME"] 获取当前脚本的路径,如:index.php
$_SERVER["PHP_SELF"] 当前正在执行脚本的文件名
总结一下,对于QUERY_STRING,REQUEST_URI,SCRIPT_NAME和PHP_SELF,深入了解将有利于我们 在$_SERVER函数中正确调用这四个值。通过实例详解$_SERVER函数中 QUERY_STRING,REQUEST_URI,SCRIPT_NAME和PHP_SELF掌握四个变量之间的区别。
