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
发布时间：2024-10-29 点击：36
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$['']获取的浏览器信息，我们可以通过下面的例子来了解：
结果将输出：
/4.0
(; msie 6.0; nt 5.1; sv1; .net clr 1.1.4322)
(
[] => ^/.\.0
(; msie 6\.0.*;.* nt 5\.1.*\.net clr.*).*$
[] => /?.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：

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：

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$['']获取的浏览器信息，我们可以通过下面的例子来了解：
结果将输出：
/4.0
(; msie 6.0; nt 5.1; sv1; .net clr 1.1.4322)
(
[] => ^/.\.0
(; msie 6\.0.*;.* nt 5\.1.*\.net clr.*).*$
[] => /?.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：

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。
