一下使用php判斷瀏覽器類型的方法發(fā)現(xiàn)解決這個問題很簡單
2021-10-16
今天的項目需要根據(jù)用戶的瀏覽器類型進行不同的處理，所以稍微研究了一下使用php判斷瀏覽器類型的方法，發(fā)現(xiàn)解決這個問題其實很簡單，只要熟悉常量$ [''] 用法就行。接下來我們寫一個php通過$['']判斷瀏覽器類型的方法。
function my_get_browser(){
if(empty($_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($_SERVER['HTTP_USER_AGENT'],'360SE')){
return '360SE';
}
}
這里主要使用$['']，這個常量用來檢查頁面的訪問者使用的是什么操作系統(tǒng)（包括版本號）、瀏覽器（包括版本號）和用戶個人偏好。用法非常簡單。您可以通過在程序中打印出來來理解它。
另外，PHP還可以使用PHP系統(tǒng)函數(shù)()函數(shù)來判斷瀏覽器類型，它會返回用戶瀏覽器的一些性能數(shù)據(jù)。此功能通過查詢用戶的 .ini 文件來衡量用戶瀏覽器的性能。如果成功，該函數(shù)返回一個包含用戶瀏覽器信息的對象或數(shù)組，如果失敗，則返回。
語法
(,)
該函數(shù)有兩個參數(shù)，參數(shù)含義解釋如下：
可選的。指定 HTTP 用戶代理的名稱。默認(rèn)值為 $ 的值。您可以通過設(shè)置 NULL 來繞過此參數(shù)。
可選的。如果此參數(shù)設(shè)置為 true，則此函數(shù)將返回一個數(shù)組而不是一個對象。
對于php通過$['']獲取的瀏覽器信息，我們可以通過下面的例子來了解：
"; $browser = get_browser(null,true); print_r($browser); ?>
結(jié)果將輸出：
/4.0
(; MSIE 6.0; NT 5.1; SV1; .NET CLR 1.1.4322)
(
[] => ^/.\.0
(; msie 6\.0.*;.* nt 5\.1.*\.net clr.*).*$
[] => /?.0
(; MSIE 6.0*;* NT 5.1*.NET CLR*)*
[] => IE 6.0
[] =>
[] => 1
[] => IE
[] => 6.0
[] => 6
[] => 0
[CSS] => 2
[] => 1
[] => 1
[] => 1
[] => 1
[] => 1
[] => 1
[] => 1
[] => 1
[] => 1
[cdf] => 1
[aol] =>
[測試版] =>
[] =>
[] =>
[] =>
[wap] =>
[ak] =>
[sk] =>
)
但是php獲取服務(wù)器ie版本，通過PHP()函數(shù)獲取客戶端瀏覽器的相關(guān)信息是有條件的。如果直接使用，一般會報如下錯誤：
:() [.get-]: ini 中沒有設(shè)置......
通過查詢php手冊，解釋是：要使用這個功能，必須在php.ini文件中加一句指向.ini文件的配置。.ini 文件記錄了所有現(xiàn)有瀏覽器的類型和信息。所以你必須下載最新的文件，下載 .ini 并將它放在服務(wù)器上的某個位置。()使用時，將獲取到的客戶端信息與該文件進行比較，如果可以找到，則返回對應(yīng)的類型。
從以上來看，使用()獲取瀏覽器類型的代價不小！
PHP 還有一種判斷瀏覽器類型的方法，就是使用國外專家寫的開源代碼。有個叫國外的網(wǎng)站，里面有關(guān)于瀏覽器的項目，并且不斷更新寫的類。我看到的最新類可以獲取包括，win，mac，OS，BeOS等平臺的瀏覽器信息，功能可以說是非常強大了。下載此文件時，應(yīng)根據(jù)您使用的 PHP 版本進行選擇。該類的具體代碼如下：
getBrowser() == Browser::BROWSER_FIREFOX && $browser->getVersion() >= 2 ) {
* echo 'You have FireFox version 2 or greater';
* }

這個類的用法也很簡單，如下：
$obj_browser = new Browser; //創(chuàng)建一個此類的一個實例 $obj_browser->getBrowser(); //調(diào)用相關(guān)函數(shù)，獲取瀏覽器名稱 $obj_browser->getPlatform(); //調(diào)用相關(guān)函數(shù)，獲取系統(tǒng)名稱 $obj_browser->isMobile(); //判斷來訪者所用設(shè)備是iPhone、iPad或者電腦（PC）
好了，到此為止php獲取服務(wù)器ie版本，通過php判斷瀏覽器類型的方法就總結(jié)了。有三種方法，但是如果準(zhǔn)確率不是那么高，第一種完全可以，第二種和第三種方法有點過于精細(xì)， 無法確定復(fù)雜性但很明顯。
另外，如果想知道如何判斷瀏覽器類型，可以參考本站文章：
