PHP判断浏览器、判断语言代码分享

PHP编程中经常需要用到一些服务器的一些资料，特把$_SERVER的详细参数整理下，方便以后使用。

判断浏览器类型

//判断类型
<?php
if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0"))
echo "Internet Explorer 8.0";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 7.0"))
echo "Internet Explorer 7.0";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0"))
echo "Internet Explorer 6.0";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/3"))
echo "Firefox 3";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2"))
echo "Firefox 2";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome"))
echo "Google Chrome";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari"))
echo "Safari";
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera"))
echo "Opera";
else echo $_SERVER["HTTP_USER_AGENT"];
?>

判断语言

<?php
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4); //只取前4位，这样只判断最优先的语言。如果取前5位，可能出现en,zh的情况，影响判断。
if (preg_match("/zh-c/i", $lang))
echo "简体中文";
else if (preg_match("/zh/i", $lang))
echo "繁體中文";
else if (preg_match("/en/i", $lang))
echo "English";
else if (preg_match("/fr/i", $lang))
echo "French";
else if (preg_match("/de/i", $lang))
echo "German";
else if (preg_match("/jp/i", $lang))
echo "Japanese";
else if (preg_match("/ko/i", $lang))
echo "Korean";
else if (preg_match("/es/i", $lang))
echo "Spanish";
else if (preg_match("/sv/i", $lang))
echo "Swedish";
else echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];
?>

判断浏览器内核的PHP程序

<?php
error_reporting(E_ALL & ~ E_NOTICE);
class clientGetObj
{
function getBrowse()
{
global $_SERVER;
$Agent = $_SERVER['HTTP_USER_AGENT'];
$browser = '';
$browserver = '';

for($i = 0; $i <= 7; $i ++){
if(strpos($Agent, $Browsers[$i])){
$browser = $Browsers[$i];
$browserver = '';
}
}
if(preg_match('/Mozilla/', $Agent) && !preg_match('/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;

} else {
$browseinfo = false;

return $browseinfo;
}  

function getIP ()
{
global $_SERVER;
