我使用的是php 5.3 Centos6。我已经安装了mysql。但是当我在phpinfo中看到“configure command”时，它会显示'--without-mysql'。
如何在PHP配置文件中添加'--with-mysql'。

您必须安装php-mysqlnd或php-mysqli扩展。请查看here以获取解释。
yum install php-mysqlnd

--without-mysql和--with-mysql指的是编译设置。您可以使用yum命令安装预编译的二进制文件。
要明确：--with-mysql不是php配置设置，而是使用php源完成的事情。
正如@Andrew所说，安装php-mysqlnd扩展程序最有意义。这本质上是一个PHP源代码片段，给出了--with-mysql指令。 （最后一句话被大量改述）。
