thinkphp3.2评论回复点赞功能-CFANZ编程社区

1.composer下载thinkphp3.2

composer create-project topthink/thinkphp your-project-name

2.创建数据库

CREATE TABLE `comments` (
	`id` INT ( 11 ) UNSIGNED NOT NULL AUTO_INCREMENT,
	`content` text COLLATE utf8_unicode_ci NOT NULL,
	`user_id` INT ( 11 ) UNSIGNED NOT NULL,
	`parent_id` INT ( 11 ) UNSIGNED DEFAULT NULL,
	`likes` INT ( 11 ) NOT NULL DEFAULT '0',
	`created_at` datetime NOT NULL,
PRIMARY KEY ( `id` ) 
) ENGINE = INNODB AUTO_INCREMENT = 9 DEFAULT CHARSET = utf8 COLLATE = utf8_unicode_ci;

3.连接数据库

Application\Common\Conf\
<?php
return array(
	//'配置项'=>'配置值'
    //数据库配置信息
    'DB_TYPE'   => 'mysql', // 数据库类型
    'DB_HOST'   => '127.0.0.1', // 服务器地址
    'DB_NAME'   => 'comments', // 数据库名
    'DB_USER'   => 'root', // 用户名
    'DB_PWD'    => '123456', // 密码
    'DB_PORT'   => 3306, // 端口
    'DB_PARAMS' =>  array(), // 数据库连接参数
    'DB_PREFIX' => '', // 数据库表前缀
    'DB_CHARSET'=> 'utf8', // 字符集
    'DB_DEBUG'  =>  TRUE, // 数据库调试模式 开启后可以记录SQL日志
);
