This article mainly introduces php to determine the current operating system type, which can be either a server or a client, if you are interested, refer to how to use php to obtain the current operating system type? Strictly speaking, here
Two casesOne is to obtain the operating system type of the server, and the other is to obtain the operating system type of the client. The authors will share with you how to use php to obtain the operating system types in these two cases.
(1) php obtains the operating system type of the server.
In this case, you can use the built-in php System
Constant PHP_ OSOr system functions
Php_uname ('s ')
.The possible values returned by the two methods are as follows:

- IRIX64
- SunOS
- HP-UX
- OpenBSD
However, based on the actual situation, the reader still prints out the results to see the best results. The results may not be listed above.
(2) php obtains the operating system type of the client. Here we share a function, which is more accurate than the judgments circulating on the Internet and has no bugs. the Function code is as follows:
function getOS(){ $os=''; $Agent=$_SERVER['HTTP_USER_AGENT']; if (eregi('win',$Agent)&&strpos($Agent, '95')){ $os='Windows 95'; }elseif(eregi('win 9x',$Agent)&&strpos($Agent, '4.90')){ $os='Windows ME'; }elseif(eregi('win',$Agent)&&ereg('98',$Agent)){ $os='Windows 98'; }elseif(eregi('win',$Agent)&&eregi('nt 5.0',$Agent)){ $os='Windows 2000'; }elseif(eregi('win',$Agent)&&eregi('nt 6.0',$Agent)){ $os='Windows Vista'; }elseif(eregi('win',$Agent)&&eregi('nt 6.1',$Agent)){ $os='Windows 7'; }elseif(eregi('win',$Agent)&&eregi('nt 5.1',$Agent)){ $os='Windows XP'; }elseif(eregi('win',$Agent)&&eregi('nt',$Agent)){ $os='Windows NT'; }elseif(eregi('win',$Agent)&&ereg('32',$Agent)){ $os='Windows 32'; }elseif(eregi('linux',$Agent)){ $os='Linux'; }elseif(eregi('unix',$Agent)){ $os='Unix'; }else if(eregi('sun',$Agent)&&eregi('os',$Agent)){ $os='SunOS'; }elseif(eregi('ibm',$Agent)&&eregi('os',$Agent)){ $os='IBM OS/2'; }elseif(eregi('Mac',$Agent)&&eregi('PC',$Agent)){ $os='Macintosh'; }elseif(eregi('PowerPC',$Agent)){ $os='PowerPC'; }elseif(eregi('AIX',$Agent)){ $os='AIX'; }elseif(eregi('HPUX',$Agent)){ $os='HPUX'; }elseif(eregi('NetBSD',$Agent)){ $os='NetBSD'; }elseif(eregi('BSD',$Agent)){ $os='BSD'; }elseif(ereg('OSF1',$Agent)){ $os='OSF1'; }elseif(ereg('IRIX',$Agent)){ $os='IRIX'; }elseif(eregi('FreeBSD',$Agent)){ $os='FreeBSD'; }elseif($os==''){ $os='Unknown'; } return $os; }
The method is determined based on the server side or the client side. I hope you will know how to use php to obtain the current operating system type through this article.
