php如何判断当前的操作系统是linux还是windows
PHP判断当前操作系统的方法很多，比如：
1.直接使用PHP预定义常量PHP_OS来获取；
?php
header(“Content-type:text/html;charset=utf-8;”);
$os_name=PHP_OS;
if(strpos($os_name,”Linux”)!==false){
$os_str=”Linux操作系统”;
}else if(strpos($os_name,”WIN”)!==false){
$os_str=”Windows操作系统”;
}
echo $os_str;
2.还可以通过用户浏览器信息来判断操作系统。
?php
header(“Content-type:text/html;charset=utf-8;”);
//测试
echo get_user_os();
//Windows操作系统
function get_user_os(){
//获取用户浏览信息参数
$agent = $_SERVER[‘HTTP_USER_AGENT’];
//获取操作系统类型
if(strpos($agent,”NT 6.1″)){
$os_name =”Windows 7″;
} elseif(strpos($agent,”NT 5.1″)) {
$os_name =”Windows XP (SP2)”;
} elseif(strpos($agent,”NT 5.2″) strpos($agent,”WOW64″)){
$os_name =”Windows XP 64-bit Edition”;
} elseif(strpos($agent,”NT 5.2″)) {
$os_name =”Windows 2003″;
} elseif(strpos($agent,”NT 6.0″)) {
$os_name =”Windows Vista”;
} elseif(strpos($agent,”NT 5.0″)) {
$os_name =”Windows 2000″;
} elseif(strpos($agent,”4.9″)) {
$os_name =”Windows ME”;
} elseif(strpos($agent,”NT 4″)) {
$os_name =”Windows NT 4.0″;
} elseif(strpos($agent,”98″)) {
$os_name =”Windows 98″;
} elseif(strpos($agent,”95″)) {
$os_name =”Windows 95″;
}elseif(strpos($agent,”Linux”)) {
$os_name =”Linux”;
}
//判断
if(strpos($os_name,”Linux”)!==false){
$os_str=”Linux操作系统”;
}else if(strpos($os_name,”Windows”)!==false){
$os_str=”Windows操作系统”;
}else{
$os_str=”未知操作系统”;
}
return $os_str;
}
3.使用php_uname函数来获取;
?php
header(“Content-type:text/html;charset=utf-8;”);
$os_name=php_uname();
if(strpos($os_name,”Linux”)!==false){
$os_str=”Linux操作系统”;
}else if(strpos($os_name,”Windows”)!==false){
$os_str=”Windows操作系统”;
}
echo $os_str;
如何解决OS X系统中PHP不支持Freetype的问题
为了方便显示PHP的信息，写了一个test.php页面，页面的代码很简单：打开页面后，发现当前的PHP版本是5.5，并且GD已经开启，但是没有Freetype库。原来在OSXYosemite10.10自带的PHP是没有将Freetype编译进去的。不过我找了一个简单的法，继续看下去。打开终端，输入命令：curl-sphp-osx.liip.ch/install.shbash-s5.6PS：大家可以直接访问php-osx.liip.ch，虽然是英文，但是介绍是清晰的安装完后，重新打开test.php，PHP的版本已经变成5.6，并且Freetype都已经安装。再打开项目，验证码能够正常显示了。

此PHP类，根据操作系统来进行判断。

php_os显示结果是WINNT 可是我的系统是win 7呀?是怎么回事?
和你的系统是win 7 还是win 8没有关系，php环境检测的时候，微软的windows系统都是这样显示的
只要是windows系统，都是显示的WINNT
WINNT 表示的是你的系统环境是windows
win 7 表示的是你的系统版本是 windows7
一个是系统环境，一个是系统版本
