In order to have these functions available, you must compile PHP with support for the mysqli extension.
Hinweis:
The mysqli extension is designed to work with MySQL version 4.1.13 or newer, or 5.0.7 or newer. For previous versions, please see the MySQL extension documentation.
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.
