推荐答案

PHP有许多 <通常有用的strong>预定义常量 .

PHP has many predefined constants that are often useful.

在这里， PHP_OS 是您要寻找的人.

Here, PHP_OS is the one you are looking for.

例如，在我当前的计算机上，此代码:

For instance, on my current machine, this code :

var_dump(PHP_OS);

送礼:

string 'Linux' (length=5)

您可以通过 php_uname 功能获得一些示例和比较，从而获得 php_uname 的手册页；例如(引用):

You have some examples and comparisons with what the php_uname function can get you on the manual page of php_uname ; for instance (quoting) :

<?php
echo php_uname();
echo PHP_OS;

/* Some possible outputs:
Linux localhost 2.4.21-0.13mdk #1 Fri Mar 14 15:08:06 EST 2003 i686
Linux

FreeBSD localhost 3.2-RELEASE #15: Mon Dec 17 08:46:02 GMT 2001
FreeBSD

Windows NT XN1 5.1 build 2600
WINNT
*/

if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
    echo 'This is a server using Windows!';
} else {
    echo 'This is a server not using Windows!';
}

该页面还显示:

仅用于操作的名称 系统，请考虑使用PHP_OS 不变，但请记住这一点 常量将包含操作 系统PHP已构建.

For the name of just the operating system, consider using the PHP_OS constant, but keep in mind this constant will contain the operating system PHP was built on.
