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.
