1、下面我們就來通過 $_SERVER['HTTP_USER_AGENT'] 來寫一個php判斷浏覽器類型的辦法。
function my_get_browser(){
if(empty($_SERVER['HTTP_USER_AGENT'])){
return '命令行，機器人來了！';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 9.0')){
return 'Internet Explorer 9.0';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 8.0')){
return 'Internet Explorer 8.0';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 7.0')){
return 'Internet Explorer 7.0';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 6.0')){
return 'Internet Explorer 6.0';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Firefox')){
return 'Firefox';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Chrome')){
return 'Chrome';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Safari')){
return 'Safari';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Opera')){
return 'Opera';
}
if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'360SE')){
return '360SE';
}
}
這裡主要用到了 $_SERVER['HTTP_USER_AGENT']，這個常量是用來檢查浏覽頁面的訪問者在用什麼操作系統（包括版本號）浏覽器（包括版本號）和用戶個人偏好。用法很簡單，自己在程序裡面打印出來看看就明白了。
2、另外 php 判斷浏覽器的類型還可以通過 php 系統函數 get_browser() 函數，這個函數將會返回用戶浏覽器的一些性能數據。
該函數通過查閱用戶的 browscap.ini 文件，來測定用戶浏覽器的性能。若成功，則該函數返回包含用戶浏覽器信息的一個對象或一個數組，若失敗，則返回 false。get_browser 語法get_browser(user_agent,return_array)這個函數有兩個參數，參數意義解釋如下：user_agent 可選。規定 HTTP 用戶代理的名稱。默認是 $HTTP_USER_AGENT 的值。您可以通過設置 NULL 繞過該參數。
return_array 可選。如果該參數設置為 true，本函數會返回一個數組而不是對象。對於 php 通過 $_SERVER['HTTP_USER_AGENT'] 和 get_browser 獲取的浏覽器信息，我們可以通過如下例子來認識一下：
<?php
echo $_SERVER['HTTP_USER_AGENT'] . "<br /><br />";
$browser = get_browser(null,true);
print_r($browser);
?>
結果將輸出：
Mozilla/4.0
(compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)Array(
[browser_name_regex] => ^mozilla/..0
(compatible; msie 6.0.*;.*windows nt 5.1.*.net clr.*).*$
[browser_name_pattern] => Mozilla/?.0
(compatible; MSIE 6.0*;*Windows NT 5.1*.NET CLR*)*
[parent] => IE 6.0
[platform] => WinXP
[netclr] => 1
[browser] => IE
[version] => 6.0
[majorver] => 6
[minorver] => 0
[css] => 2
[frames] => 1
[iframes] => 1
[tables] => 1
[cookies] => 1
[backgroundsounds] => 1
[vbscript] => 1
[javascript] => 1
[javaapplets] => 1
[activexcontrols] => 1
[cdf] => 1
[aol] =>
[beta] =>
[win16] =>
[crawler] =>
[stripper] =>
[wap] =>
[ak] =>
[sk] =>
)
但是通過PHP的get_browser()函數獲取客戶端浏覽器相關信息是有條件的，如果你直接使用一般會報出如下這個錯誤：
Warning: get_browser() [function.get-browser]: browscap ini directive not set in ......
通過查詢 php 手冊，得到的解釋是：為了使用這個函數，你必須在php.ini文件裡面增加一句指向 browscap.ini 文件的配置，browscap.ini文件裡面記錄了所有已存在的浏覽器的類型及其信息，所以你要下載最新的這個文件，下載browscap.ini後放到服務器某個位置，get_browser()在使用時就是將獲取的客戶端信息與此文件進行對比，如果能找到，則返回相應類型。由上看來要想使用 get_browser() 獲取浏覽器類型代價不小啊！
3、另外還有一種php判斷浏覽器類型的辦法，即使用一個國外牛人寫的開源代碼。國外有個叫mavrick的網站，上面有關於浏覽器的項目，一直更新所寫的Browser類，我最新看到的這個類可以獲取包括iPhone、BlackBerry、win、mac、linux、OS、BeOS等平台上的浏覽器信息，功能可以說是十分強大。
下載這個文件時要根據自己使用的PHP版本去選擇。該類的具體代碼如下：

這個類的使用方法也很簡單，如下：
$obj_browser = new Browser; //創建一個此類的一個實例
$obj_browser->getBrowser(); //調用相關函數，獲取浏覽器名稱
$obj_browser->getPlatform(); //調用相關函數，獲取系統名稱
$obj_browser->isMobile(); //判斷來訪者所用設備是iPhone、iPad或者電腦（PC）
ok，至此通過 php 判斷浏覽器類型的方法已經總結完了，三種辦法，但如果要求精度不是那麼高的話，第一種完全可以了，第二種，第三種辦法實在有點太過精細了而且靠譜度未能確定復雜度卻顯而易見。
