本文实例讲述了PHP实现的浏览器检查类。分享给大家供大家参考,具体如下:
- <?php
- //原作者:epsilon7
- //SonyMusic([email]sonymusic@163.net[/email])
- class BrowserDetector {
- var $UA = ""; //$HTTP_USER_AGENT的内容
- var $BROWSER= "Unknown"; //浏览器类型
- var $PLATFORM = "Unknown"; //操作系统
- var $VERSION= ""; //浏览器版本号
- var $MAJORVER = ""; //浏览器主版本号
- var $MINORVER = ""; //浏览器副版本号
- /* 构造函数开始 */
- function BrowserDetector(){
- $this->UA = getenv(HTTP_USER_AGENT);
- $preparens = "";
- $parens = "";
- $i = strpos($this->UA,"(");
- if ($i >= 0) {
- $preparens = trim(substr($this->UA,0,$i));
- $parens = substr($this->UA,$i+1,strlen($this->UA));
- $j = strpos($parens,")");
- if($j>=0) {
- $parens = substr($parens,0,$j);
- }
- }
- else {
- $preparens = $this->UA;
- }
- $browVer = $preparens;
- $token = trim(strtok($parens,";"));
- while($token) {

- }
- elseif(preg_match("/MSIE/i","$token")) {

- }
- $msieIndex = strpos($browVer,"MSIE");
- if($msieIndex >= 0) {
- $browVer = substr($browVer,$msieIndex,strlen($browVer));
- }
- $leftover = "";
- if(substr($browVer,0,strlen("Mozilla")) == "Mozilla") {

- $leftover=substr($browVer,strlen("Microsoft Internet Explorer")+1,strlen($browVer));
- }
- elseif(substr($browVer,0,strlen("Opera")) == "Opera") {
- $this->BROWSER = "Opera";
- $leftover=substr($browVer,strlen("Opera")+1,strlen($browVer));
- }
- $leftover = trim($leftover);
- $i=strpos($leftover," ");
- if($i > 0) {
- $this->VERSION = substr($leftover,0,$i);
- }
- else {
- $this->VERSION = $leftover;
- }
- $j = strpos($this->VERSION,".");
- if($j >= 0) {
- $this->MAJORVER = substr($this->VERSION,0,$j);
- $this->MINORVER = substr($this->VERSION,$j+1,strlen($this->VERSION));
- }
- else {
- $this->MAJORVER = $this->VERSION;
- }
- }
- }
- //测试程序开始
- $test=new browserdetector;
- echo $test->UA."<br>";
- echo $test->BROWSER."<br>";
- echo $test->PLATFORM."<br>";
- echo $test->VERSION."<br>";
- echo $test->MAJORVER."<br>";
- echo $test->MINORVER."<br>";
- ?>
