Php method for obtaining the user's browser version

This article describes how to obtain the user's browser version in php. it is very useful to use $ _ SERVER [HTTP_USER_AGENT] to obtain user information, for more information about how to obtain the user's browser version, see the example in this article. Share it with you for your reference. The specific analysis is as follows:

In php, we have a global variable $ _ SERVER ['http _ USER_AGENT ']; which can obtain all user information. we need to process it before determining the type of user browser, the following function can accurately code the user's browser version number.

The code is as follows:

Function getbrowse ()
{
$ Agent = $ _ server ['http _ user_agent '];
$ Browser = '';
$ Browserver = '';
$ Browser = array ('Lynx ', 'Mosaic', 'AOL ', 'Opera', 'Java', 'macweb', 'webexplorer ', 'omniweb ');
For ($ I = 0; $ I <= 7; $ I ++ ){
If (strpos ($ agent, $ browsers [$ I]) {
$ Browser = $ browsers [$ I];
$ Browserver = '';
}
}
If (ereg ('mozilla ', $ agent )&&! Ereg ('msie ', $ agent )){
$ Temp = explode (', $ agent );
$ Part = $ temp [0];
$ Temp = explode ('/', $ part );
$ Browserver = $ temp [1];
$ Temp = explode ('', $ browserver );
$ Browserver = $ temp [0];
$ Browserver = preg_replace ('/([d.] +)/', '\ 1', $ browserver );
$ Browserver = $ browserver;
$ Browser = 'Netscape Navigator ';
}
If (ereg ('mozilla ', $ agent) & ereg ('Opera', $ agent )){
$ Temp = explode (', $ agent );
$ Part = $ temp [1];
$ Temp = explode (')', $ part );
$ Browserver = $ temp [1];
$ Temp = explode ('', $ browserver );
$ Browserver = $ temp [2];
$ Browserver = preg_replace ('/([d.] +)/', '\ 1', $ browserver );
$ Browserver = $ browserver;
$ Browser = 'Opera ';
}
If (ereg ('mozilla ', $ agent) & ereg ('msie', $ agent )){
$ Temp = explode (', $ agent );
$ Part = $ temp [1];
$ Temp = explode (';', $ part );
$ Part = $ temp [1];
$ Temp = explode ('', $ part );
$ Browserver = $ temp [2];
$ Browserver = preg_replace ('/([d.] +)/', '\ 1', $ browserver );
$ Browserver = $ browserver;
$ Browser = 'Internet explorer ';
}
If ($ browser! = ''){
$ Browseinfo = $ browser. ''. $ browserver;
} Else {
$ Browseinfo = false;
}
Return $ browseinfo;
}
// Application method

// In ie
Echo getbrowse (); // internet explorer 6.0
// In firefox
Echo getbrowse (); // netscape navigator 5.0
