我从http://www.php.net/manual/en/configure.about.php找到它
这些是 PHP 编译的配置选项
--with-apache[=DIR]
Build a static Apache module. DIR is the top-level Apache build directory, defaults to /usr/local/apache.
--with-apxs2[=FILE]
Build shared Apache 2.0 module. FILE is the optional pathname to the Apache apxs tool; defaults to apxs.
静态和共享是什么意思?
