一下使用php判斷瀏覽器類型的方法發(fā)現(xiàn)解決這個(gè)問(wèn)題很簡(jiǎn)單
2023-11-25 分類： 網(wǎng)站建設(shè)
今天的項(xiàng)目需要根據(jù)用戶的瀏覽器類型進(jìn)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(gè)問(wèn)題其實(shí)很簡(jiǎn)單，只要熟悉常量$ [''] 用法就行。接下來(lái)我們寫一個(gè)php通過(guò)$['']判斷瀏覽器類型的方法。
function my_get_browser(){
if(empty($_SERVER['HTTp_USER_AGENT'])){
return '命令行，機(jī)器人來(lái)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(gè)常量用來(lái)檢查頁(yè)面的訪問(wèn)者使用的是什么操作系統(tǒng)（包括版本號(hào)）、瀏覽器（包括版本號(hào)）和用戶個(gè)人偏好。用法非常簡(jiǎn)單。您可以通過(guò)在程序中打印出來(lái)來(lái)理解它。
另外，pHp還可以使用pHp系統(tǒng)函數(shù)()函數(shù)來(lái)判斷瀏覽器類型，它會(huì)返回用戶瀏覽器的一些性能數(shù)據(jù)。此功能通過(guò)查詢用戶的 .ini 文件來(lái)衡量用戶瀏覽器的性能。如果成功，該函數(shù)返回一個(gè)包含用戶瀏覽器信息的對(duì)象或數(shù)組，如果失敗，則返回。
語(yǔ)法
(,)
該函數(shù)有兩個(gè)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(guò)設(shè)置 NULL 來(lái)繞過(guò)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(gè)數(shù)組而不是一個(gè)對(duì)象。
對(duì)于php通過(guò)$['']獲取的瀏覽器信息，我們可以通過(guò)下面的例子來(lái)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(cè)試版] =>
[] =>
[] =>
[] =>
[wap] =>
[ak] =>
[sk] =>
)
但是php獲取服務(wù)器ie版本，通過(guò)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(huì)報(bào)如下錯(cuò)誤：
:() [.get-]: ini 中沒(méi)有設(shè)置......
通過(guò)查詢php手冊(cè)，解釋是：要使用這個(gè)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(gè)位置。()使用時(shí)，將獲取到的客戶端信息與該文件進(jìn)行比較，如果可以找到，則返回對(duì)應(yīng)的類型。
從以上來(lái)看，使用()獲取瀏覽器類型的代價(jià)不小！
pHp 還有一種判斷瀏覽器類型的方法，就是使用國(guó)外專家寫的開(kāi)源代碼。有個(gè)叫國(guó)外的網(wǎng)站，里面有關(guān)于瀏覽器的項(xiàng)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(tái)的瀏覽器信息，功能可以說(shuō)是非常強(qiáng)大了。下載此文件時(shí)，應(yīng)根據(jù)您使用的 pHp 版本進(jìn)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(gè)類的用法也很簡(jiǎn)單，如下：

好了，到此為止php獲取服務(wù)器ie版本，通過(guò)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(diǎn)過(guò)于精細(xì)， 無(wú)法確定復(fù)雜性但很明顯。
