主要是获取到地址栏的一些信息，域名，端口参数等
代码如下:
PHP
//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']."
";
?>
//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 $_SERVER['HTTP_REFERER']."
";
?>
PHP 获得当前的脚本网址(只有路径)
代码如下:
function GetCurUrl()
{
if(!empty($_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 $nowurl;
}
//实例调用方法
//echo GEtCurUrl();
{
if(!empty($_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;
}
//实例调用方法
//echo GEtCurUrl();
PHP 获取URL地址不包含路径（域名或ip地址）
代码如下:
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();
{
$ServerName = strtolower($_SERVER['SERVER_NAME']?$_SERVER['SERVER_NAME']:$_SERVER['HTTP_HOST']);
if( strpos($ServerName,'http://') )
{
return str_replace('http://','',$ServerName);
}
return $ServerName;
}
//实例调用方法
echo getServerName();
PHP 获取URL地址包含端口路径
代码如下:
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
