Question

php代码帮忙解释下意思！！！！

<?php
/********密码验证***********/
$password='123456'; //这个密码是登陆验证用的.您需要在模块里设置和这里一样的密码....注意一定需要修改.
if($password!=$_GET['pw']) exit('验证密码错误'); //安全检测,密码不符则退出

/*******载入系统配置********/

define('PHPCMS_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR);
include PHPCMS_PATH.'/phpcms/base.php';
//pc_base::creat_app();
$db_config = pc_base::load_config('database');
pc_base::load_sys_class('mysql', '', 0);
pc_base::load_sys_class('param', '', 0);
pc_base::load_model('content_model');
$db=new mysql();
$db->open($db_config['default']);
$pre=$db_config['default']['tablepre'];
$db->connect();
$cates=$db->select('`catid` as cid,`parentid` as pid,`catname` as cname',"{$pre}category","type=0 and child=0");

Answer 1

什么情况？
define('PHPCMS_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR);//定义常量
include PHPCMS_PATH.'/phpcms/base.php';//引入文件
//pc_base::creat_app();
$db_config = pc_base::load_config('database');//调用pc_base类里的load_config方法，下面三个一样
pc_base::load_sys_class('mysql', '', 0);
pc_base::load_sys_class('param', '', 0);
pc_base::load_model('content_model');
$db=new mysql();//实例化类mysl,下面这些是这个类里面的方法
$db->open($db_config['default']);
$pre=$db_config['default']['tablepre'];
$db->connect();
$cates=$db->select('`catid` as cid,`parentid` as pid,`catname` as cname',"{$pre}category","type=0 and child=0");

可能有自己的类 调用了
