$serversoft=$_SERVER["SERVER_SOFTWARE"];
$apache=explode("/",$serversoft,-1);
//$apache['0']是apache,$apache['1']是“2.0.49 (Win32) PHP”
//把“2.0.49 (Win32) PHP ”赋值给$apaches
$apaches=$apache['1'];
//继续用“（”分隔$apaches
$apacheversion=explode("(",$apaches,-1);
//连接字符串
$apacheversion=$apache['0'].$apacheversion['0'];
echo $apacheversion;
后来发现直接用 apache_get_version()就可以了.
晕倒~!~
