swoole-orm

基于swoole的mysql协程连接池,简单封装。  
实现多个协程间共用同一个协程客户端

感谢完善

[1]:nowbe -> 新增数据返回insert_id

版本

v0.0.1

1、初完成

v0.0.2

1、修复find()查询bug

v0.0.3

1、将splqueque修改为channel
2、添加lock()
3、添加日志
4、表前缀

v0.0.4

1、添加setDefer -> 设置是否返回结果(默认为true。部分操作,例如insert,update等,如果不需要返回返回结果,则可以设置为false)
2、使用go处理协程
3、完善日志功能

v0.0.5

1、去掉日志功能,修改为在log文件打印错误信息和抛出异常
2、添加断线重连功能
3、添加instance()函数,如果有特殊需求扩展无法实现,又想共用连接池时,譬如事务处理,此时可以通过instance获取一个连接
4、添加put()函数,配合instance使用,使用完连接后,将连接put回连接池里
5、find()函数bug修复,返回一维数组

入门例子

<?php
namespace Demo;

include_once "./vendor/autoload.php";

use sethink\swooleOrm\Db;
use sethink\swooleOrm\MysqlPool;
use swoole;

class Demo
{
    protected $server;
    protected $MysqlPool;

    public function __construct()
    {
        $this->server = new Swoole\Http\Server("0.0.0.0", 9501);
        $this->server->set(array(
            'worker_num'    => 4,
            'max_request'   => 50000,
            'reload_async'  => true,
            'max_wait_time' => 30,
        ));

        $this->server->on('Start', function ($server) {});

    {
        $config = [
            'host'      => '127.0.0.1', //服务器地址
            'port'      => 3306,    //端口
            'user'      => 'root',  //用户名
            'password'  => 'root',  //密码
            'charset'   => 'utf8',  //编码
            'database'  => 'test',  //数据库名
            'prefix'    => 'sethink_',  //表前缀
            'poolMin'   => 5, //空闲时,保存的最大链接,默认为5
            'poolMax'   => 1000,    //地址池最大连接数,默认1000

            'setDefer'  => true,     //设置是否返回结果,默认为true,
        ];
        $this->MysqlPool = new MysqlPool($config);
        unset($config);
        
        //执行定时器
        $this->MysqlPool->clearTimer($server);
    }

    public function onRequest($request, $response)
    {
        $rs = Db::init($this->MysqlPool)
            ->name('tt')
            ->select();
        var_dump($rs);
    }
}

new Demo();

基本使用

查询

查询单条

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username,info')
    ->where(['username'=>'sethink','password'=>'sethink'])
    ->find();

查询多条

<?php
Db::init($this->MysqlPool)
    ->name('info')
    ->field('id,username,password,info')
    ->select();

添加

添加单条数据

<?php
$data = [
    'username' => 'sethink2',
    'password' => 'sethink2',
    'info'     => 'ceshi2'
];

Db::init($this->MysqlPool)
    ->name('user_info')
    ->insert($data);

批量添加

<?php
$data = [
    [
        'username' => 'sethink3',
        'password' => 'sethink3',
        'info'     => 'ceshi3'
    ],
    [
        'username' => 'sethink4',
        'password' => 'password4',
        'info'     => 'ceshi4'
    ]
];

Db::init($this->MysqlPool)
    ->name('user_info')
    ->insertAll($data);

更新数据

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->where(['username'=>'sethink4'])
    ->update(['password'=>'sethink4-4']);

删除数据

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->where(['username'=>'sethink4'])
    ->delete();

详解

init($server)

$server为swoole服务器

instance()

如果有特殊需求扩展无法实现,又想共用连接池时,譬如事务处理,此时可以通过instance获取一个连接

例子:

<?php
$mysql = Db::init($this->MysqlPool)->instance();

put($mysql)

配合instance使用,使用完连接后,将连接put回连接池里

例子:

<?php
$mysql = Db::init($this->MysqlPool)->instance();
$mysql->query('select * from `user_info`');
Db::init($this->MysqlPool)->put($mysql);

name($tableName)

$tableName为表名   --  字符串

field($field)

$field为查询的字段名   --  字符串

order($order)

order by排序  --  数组(一维数组或者二维数组)

例子: $order为一维数组时

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->order(['id'=>'desc'])
    ->select();

$order为二维数组时

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->order([['id'=>'desc'],['info'=>'asc']])
    ->select();

group($group)

group by分组  --  字符串

例子:

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->group('info')
    ->select();

### having($having)

用于配置group从分组中筛选数据   --  字符串

例子:

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->group('info')
    ->having('count(info) > 5')
    ->select();

distinct($distinct)

数据去重
$distinct为bool值

例子:

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->distinct(true)
    ->select();

lock($state)

加锁

例子:

<?php
//1、传入bool值
Db::init($this->MysqlPool)
    ->name('user_info')
    ->where(['id'=>1])
    ->lock(true)
    ->find();
//会自动在sql语句加上FOR UPDATE

//2、传入字符串
Db::init($this->MysqlPool)
    ->name('user_info')
    ->where(['id'=>1])
    ->lock('lock in share mode')
    ->find();
//特殊锁要求

fetchSql()

获取sql语句

例子:

<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->fetchSql()
    ->select();

where($whereArray)

$whereArray为数组

例子1:

<?php
//1、
$where = [
    'id'=>'1'
];

//2、
$where = [
    'id'=>['>',5]
];

//3、
$where = [
    'username'=>['LIKE','%seth%']
];

//4、
$where = [
    'id'=>['in',['1','5']]
];

//5、
$where = [
    'note_info'=>['=','sethink','or']
];


Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->where($where)
    ->select();
<?php
Db::init($this->MysqlPool)
    ->name('user_info')
    ->field('id,username')
    ->where(['id'=>['>',5]])
    ->where(['id'=>['<=',10]])
    ->select();

find()

查询一条数据,返回一维数组

select()

查询一条或多条数据,返回二维数组

insert($data)

插入单条数据
$data为一维数组

insertAll($data)

插入多条数据
$data为二维数组

update($data)

更新数据
$data为一维数组

delete()

删除数据

query($sql)

执行sql语句 --  字符串

例子:

<?php
$sql = 'select * from `user_info`';
Db::init($this->MysqlPool)->query($sql);

setDefer($bool)

部分操作,例如insert,update等,如果不需要返回结果,则可以设置为false。

相对于$bool为true,sql执行后,由于主进程和协程间不需要再通信,可以立即往下执行程序

也可以全局设置,添加配置
$config = [
    'setDefer'  => true     //设置是否返回结果,默认为true
];
$this->MysqlPool = new MysqlPool($config);
<?php
    //此操作不会返回结果
    Db::init($this->MysqlPool)
        ->name('user_info')
        ->setDefer(false)
        ->insert(['username'=>'sethink_5']);
