mysql's Introduction

一个简单的PHP Mysql数据库操作类

依赖

  • pdo

安装

  1. composer 安装 composer require ninvfeng/mysql
  2. 引入/vendor目录下的autoload.php require 'vendor/autoload.php';

初始化

//配置
$config=[
    'host'=>'127.0.0.1',
    'port'=>3306,
    'name'=>'test'
];

//推荐使用函数进行实例化,后续操作更加方便
function db($table='null') use $config{
    static $_db;
    if(!$_db){
        $_db=new \ninvfeng\mysql($config);
    }
    return $_db->table($table);
}

db('user')->insert(['user'=>'ninvfeng','pass'=>'password']);
db('user')->insert(['user'=>'lvlv','pass'=>'password']);

db('user')->where(['user'=>'ninvfeng'])->delete();

db('user')->where(['user'=>'lvlv'])->update(['pass'=>'password2']);

查找一条

db('user')->where(['user'=>'lvlv'])->find();

查找全部

db('user')->select();

条件查找

db('user')->where(['user'=>'ninvfeng'])->select();

分页查找

db('user')->page(1)->select();

字段查找

db('user')->field('user')->select();

排序

db('user')->order('id desc')->select();

join

db('user')->join('user_info on user_info.user_id=user.id')->select();

debug 仅打印sql不执行

db('user')->debug()->select();

执行原生sql

db('user')->query("select * from user");

事务

db('user')->trans();

返回原生对象

db()->pdo();

mysql's Issues

db('user')->select();不会报错嘛?

protected function preWhere(){

    if($this->_where != '') {
        $this->_where = 'where' . trim($this->_where, 'and');
    }
    return $this;
}

将preWhere改成这样可以解决问题

发现俩个bug

发现一下俩个bug
1.debug 仅打印sql不执行
2.db('user')->field('user')->select();

function where 改成这样,可以实现$where['id']=['<',5];

public function where($where,$param=[]){

    if($param){
        $this->_param=array_merge($this->_param,$param);
    }
    if(is_array($where)){
        $res='';
        foreach($where as $k => $v){
            $column_key='';
            foreach (explode('.',$k) as $kk => $vv) {
                $column_key.=' `'.$vv.'`.';
                $column_plac='where_'.$vv;
            }
            if(is_array($v)){
                $op = ' '.$v[0].' ';
                $this->_param[$column_plac]=$v[1];
            }else{
                $op = ' = ';
                $this->_param[$column_plac]=$v;
            }
            $column_key=trim($column_key,'.');
            $res.=$column_key.$op.':'.$column_plac.' and';
        }
        $where=trim($res,'and');

    }
    $this->_where.=' '.$where.' and';

    return $this;
}

**function where 改成这样,可以实现
$where['id']=['<',5];
$where['name']=['like','%wang%'];
db('user')->where($where)->select();
**
