我本机开发用的是winXP,但是上传的服务器是linux,每次上传前总是要改一下配置文件,还有其他一些什么的,
现在通过判断当前服务器的类型来决定执行什么样的程序,那么php如何判断所处服务器是什么类型呢
php有许多系统预定义变量,通过判断他们可以简单的判断系统是 windows还是*unix
其中相关的函数或者预定义变量如下

复制代码 代码如下:


php_uname();
PHP_OS
DIRECTORY_SEPARATOR
PHP_SHLIB_SUFFIX
PATH_SEPARATOR


具体程序:

复制代码 代码如下:



if(PATH_SEPARATOR==':') echo 'Linux';
else echo 'Windows';
?>


或者

复制代码 代码如下:


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!';
}
?>
