一个常用php mysql数据库连接类
这是一很基础的东西我们能过构造函数来实现创建类就自动与mysql服务器进行连接,我们只要设置好 $name,$pass,$table三个变量的值就好了。
代码如下 | 复制代码 |
class ConnectionMySQL{ $db = new ConnectionMySQL(); |
这里我要讲述一下关于构造函数
代码如下 | 复制代码 |
//构造函数 function __construct(){ $this->ut=$ut; $this->connect(); } |
这个页面使用了构造函数特别要主要在函数中不要调用数据库连接类了,否则在当前页面会有多连接连接如果访问过大服务器就会出mysql has gone的提法哦。
