1、关于PHP重定向
代码片段
方法一：header("Location: index.php");
方法二：echo "<script>window.location ="$PHP_SELF";</script>";
方法三：echo "";
2、获取访问者浏览器
代码片段
function browse_infor()
{
$browser="";$browserver="";
$Browsers =array("Lynx","MOSAIC","AOL","Opera","JAVA","MacWeb","WebExplorer","OmniWeb");
$Agent = $GLOBALS["HTTP_USER_AGENT"];
for ($i=0; $i<=7; $i )
{
if (strpos($Agent,$Browsers[$i]))
{
$browser = $Browsers[$i];
$browserver ="";
}
}
if (ereg("Mozilla",$Agent) && !ereg("MSIE",$Agent))
{
$temp =explode("(", $Agent); $Part=$temp[0];
$temp =explode("/", $Part); $browserver=$temp[1];
$temp =explode(" ",$browserver); $browserver=$temp[0];
$browserver =preg_replace("/([d.] )/","1",$browserver);
$browserver = " $browserver";
$browser = "Netscape Navigator";
}
if (ereg("Mozilla",$Agent) && ereg("Opera",$Agent))
{
$temp =explode("(", $Agent); $Part=$temp[1];
$temp =explode(")", $Part); $browserver=$temp[1];
$temp =explode(" ",$browserver);$browserver=$temp[2];
$browserver =preg_replace("/([d.] )/","1",$browserver);
$browserver = " $browserver";
$browser = "Opera";
}
if (ereg("Mozilla",$Agent) && ereg("MSIE",$Agent))
{
$temp = explode("(", $Agent); $Part=$temp[1];
$temp = explode(";",$Part); $Part=$temp[1];
$temp = explode(" ",$Part);$browserver=$temp[2];
$browserver =preg_replace("/([d.] )/","1",$browserver);
$browserver = " $browserver";
$browser = "Internet Explorer";
}
if ($browser!="")
{
$browseinfo = "$browser$browserver";
}
else
{
$browseinfo = "Unknown";
}
return $browseinfo;
}
//调用方法$browser=browseinfo() ;直接返回结果
3、获取访问者操作系统
