php 全面获取url地址栏参数多种方法

Jun 08, 2016 pm 05:27 PM
echo quot server

我们这里总结了php 全面获取url地址栏参数多种方法哦,全部都用到了php自带的函数server

<script>ec(2);</script>
 代码如下 复制代码
//获取域名或主机地址
echo $_SERVER['HTTP_HOST']."
";
//获取网页地址
echo $_SERVER['PHP_SELF']."
";
//获取网址参数
echo $_SERVER["QUERY_STRING"]."
";
//来源网页的详细地址
echo $_SERVER['HTTP_REFERER']."
";
?>

方法二用?号表达式,

 代码如下 复制代码
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];

方法三也是一样

 代码如下 复制代码
function getServerName()
{
$ServerName = strtolower($_SERVER['SERVER_NAME']?$_SERVER['SERVER_NAME']:$_SERVER['HTTP_HOST']);
if( strpos($ServerName,'http://') )
{
return str_replace('http://','',$ServerName);
}
return $ServerName;
}
//实例调用方法
echo getServerName();

方法四,这个比较全面的获取url参数了,首先用REQUEST_URI如果服务器不支持就用PHP_SELF再不支持

 代码如下 复制代码
QUERY_STRING
function GetCurUrl()
{
if(!empty($_SERVER["REQUEST_URI"]))
{
$scrtName = $_SERVER["REQUEST_URI"];
$nowurl = $scrtName;
}
else
{
$scrtName = $_SERVER["PHP_SELF"];
if(empty($_SERVER["QUERY_STRING"]))
{
$nowurl = $scrtName;
}
else
{
$nowurl = $scrtName."?".$_SERVER["QUERY_STRING"];
}
}
return $nowurl;
}


上面这些实例,其实都用到了php $_SEVER全局变量来实现了。
