需求

为了使这些函数可用，你必须以支持mysqli扩展的方式编译PHP。

Note:
mysqli扩展被设计用于配合Mysql 4.1.13或更新的服务端版本（或者5.0.7或更新）工作。对于此前的数据库服务端版本，请参阅MySQL扩展文档。

I've just spent some time battling the "fatal error call to undefined function mysql_connect()" message, and as it wasn't clear to me, I thought it may help to say: php_mysqli does not replace the php_mysql library. It only extends it. You need the php_mysql library !

The required extensions will be pulled in automatically on FreeBSD, unless you manually remove them after installation.

If you're building this on FreeBSD, make sure that you have SPL and SimpleXML in the extensions.ini.
