PHP and "turning on" mysqli
提问by Anthony
I'm having trouble finding documentation about how exactly to go about "turning on" mysqli. I'm running OS X SL and, as I understand it, since php5 is installed, the mysqli extension should already be there as well.
我很难找到有关如何“打开”mysqli 的文档。我正在运行 OS X SL，据我所知，由于安装了 php5，mysqli 扩展也应该已经存在。
Is this as simple as adding a LoadModule line to php.ini? If I need to re-compile php, does anyone know of a good link where I could follow along to do that (so I don't goof anything up)?
这与向 php.ini 添加 LoadModule 行一样简单吗？如果我需要重新编译 php，有没有人知道一个很好的链接，我可以跟着做（所以我不会搞砸任何事情）？
Thanks in advance.
提前致谢。

As of PHP 5.0, MySQL support is no longer enabled by default with the standard PHP distributions.
从 PHP 5.0 开始，标准 PHP 发行版不再默认启用 MySQL 支持。
You will need to configure PHP with MySQLi-support. Why don't take the safe (and probably best), object oriented, road and go with the PDOclasses?
您需要使用 MySQLi 支持配置 PHP。为什么不采取安全的（可能是最好的）、面向对象的道路并使用PDO类呢？

Save yourself the headache and install the entropy PHP packageor MAMP. Getting all the commonly needed PHP modules working on OSX is non-trivial. Most people I know go with either one of those packages.
省去头疼的麻烦，然后安装entropy PHP 包或MAMP。获取所有在 OSX 上运行的常用 PHP 模块并非易事。我认识的大多数人都使用这些软件包中的任何一个。

A lot has changed since I originally posted this answer. These days, the most straight forward thing to do on OSX is to use Homebrew.

I was trying to install the MediaWiki on Snow Leopard with MySQL 5.1.41, which needed this as well. After plenty of stumbling around, the solution was extremely simple...
我试图用 MySQL 5.1.41 在 Snow Leopard 上安装 MediaWiki，它也需要这个。经过大量的磕磕绊绊，解决方案非常简单......
In /etc/php.ini, change the following lines from:
在 /etc/php.ini 中，更改以下行：
pdo_mysql.default_socket = /var/mysql/mysql.sock mysql.default_socket = /var/mysql/mysql.sock mysqli.default_socket = /var/mysql/mysql.sock
pdo_mysql.default_socket = /var/mysql/mysql.sock mysql.default_socket = /var/mysql/mysql.sock mysqli.default_socket = /var/mysql/mysql.sock
to: pdo_mysql.default_socket = /tmp/mysql.sock mysql.default_socket = /tmp/mysql.sock mysqli.default_socket = /tmp/mysql.sock
到： pdo_mysql.default_socket = /tmp/mysql.sock mysql.default_socket = /tmp/mysql.sock mysqli.default_socket = /tmp/mysql.sock
While I had linked /tmp/mysql.sock to /var/mysql, this didn't kick in until I actually edited the file.
虽然我已将 /tmp/mysql.sock 链接到 /var/mysql，但直到我实际编辑该文件时，它才起作用。

I have had this same issue.
我也遇到过同样的问题。
You need to make sure phpMyAdmin configuration file config.inc.php has the extension pointing to mysqli not mysql which is the default.
您需要确保 phpMyAdmin 配置文件 config.inc.php 的扩展名指向 mysqli 而不是 mysql 这是默认的。

If php5 was compiled with mysqli support already, then all you should need to do is point to that library in php.ini
如果 php5 已经使用 mysqli 支持编译，那么您需要做的就是在 php.ini 中指向该库
extension=mysqli.so
After adding that you will probably need to restart apache.
添加后，您可能需要重新启动 apache。
Note:The filename for the mysqli library might differ on some platforms.
注意：mysqli 库的文件名在某些平台上可能不同。
