本文跟大家分享：PHP取得客户端信息，取得客户端IP地址、浏览器类型、操作系统信息的实现方法。下面青岛星网跟俺家分享具体的实现代码。
参数：见示例；返回值：客户指定的内容。
使用方法：先建立对象：$code = new clientGetObj;然后定义需要获取的类型，比如：
1、浏览器：$str = $code->getBrowse();
2、IP地址：$str = $code->getIP();
3、操作系统：$str = $code->getOS();
class clientGetObj
{
function getBrowse()
{
global $_SERVER;
$Agent = $_SERVER['HTTP_USER_AGENT'];
$browser = '';
$browserver = '';
$Browser = array('Lynx', 'MOSAIC', 'AOL', 'Opera', 'JAVA', 'MacWeb', 'WebExplorer', 'OmniWeb');
for($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);
