一下使用php判断浏览器类型的方法发现解决这个问题很简单

2023-11-25    分类: 网站建设

今天的项目需要根据用户的浏览器类型进行不同的处理,所以稍微研究了一下使用php判断浏览器类型的方法,发现解决这个问题其实很简单,只要熟悉常量$ [''] 用法就行。接下来我们写一个php通过$['']判断浏览器类型的方法。

function my_get_browser(){
	if(empty($_SERVER['HTTp_USER_AGENT'])){
		return '命令行,机器人来了!';
	}
	if(false!==strpos($_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';
	}
}

这里主要使用$[''],这个常量用来检查页面的访问者使用的是什么操作系统(包括版本号)、浏览器(包括版本号)和用户个人偏好。用法非常简单。您可以通过在程序中打印出来来理解它。

另外,pHp还可以使用pHp系统函数()函数来判断浏览器类型,它会返回用户浏览器的一些性能数据。此功能通过查询用户的 .ini 文件来衡量用户浏览器的性能。如果成功,该函数返回一个包含用户浏览器信息的对象或数组,如果失败,则返回。

语法

(,)

该函数有两个参数,参数含义解释如下:

可选的。指定 HTTp 用户代理的名称。默认值为 $ 的值。您可以通过设置 NULL 来绕过此参数。

可选的。如果此参数设置为 true,则此函数将返回一个数组而不是一个对象。

对于php通过$['']获取的浏览器信息,我们可以通过下面的例子来了解:


"; $browser = get_browser(null,true); print_r($browser); ?>

结果将输出:

/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] =>

[测试版] =>

[] =>

[] =>

[] =>

[wap] =>

[ak] =>

[sk] =>

)

但是php获取服务器ie版本,通过pHp()函数获取客户端浏览器的相关信息是有条件的。如果直接使用,一般会报如下错误:

:() [.get-]: ini 中没有设置......

通过查询php手册,解释是:要使用这个功能,必须在php.ini文件中加一句指向.ini文件的配置。.ini 文件记录了所有现有浏览器的类型和信息。所以你必须下载最新的文件,下载 .ini 并将它放在服务器上的某个位置。()使用时,将获取到的客户端信息与该文件进行比较,如果可以找到,则返回对应的类型。

从以上来看,使用()获取浏览器类型的代价不小!

pHp 还有一种判断浏览器类型的方法,就是使用国外专家写的开源代码。有个叫国外的网站,里面有关于浏览器的项目,并且不断更新写的类。我看到的最新类可以获取包括,win,mac,OS,beOS等平台的浏览器信息,功能可以说是非常强大了。下载此文件时,应根据您使用的 pHp 版本进行选择。该类的具体代码如下:

getbrowser() == browser::bROWSER_FIREFOX && $browser->getVersion() >= 2 ) {
 *   	echo 'You have FireFox version 2 or greater';
 *   }

这个类的用法也很简单,如下:

$obj_browser = new browser; //创建一个此类的一个实例
$obj_browser->getbrowser(); //调用相关函数,获取浏览器名称
$obj_browser->getplatform(); //调用相关函数,获取系统名称
$obj_browser->isMobile(); //判断来访者所用设备是iphone、ipad或者电脑(pC) 

好了,到此为止php获取服务器ie版本,通过php判断浏览器类型的方法就总结了。有三种方法,但是如果准确率不是那么高,第一种完全可以,第二种和第三种方法有点过于精细, 无法确定复杂性但很明显。

另外,如果想知道如何判断浏览器类型,可以参考本站文章:
