22 | 23 | ## 协程调度 24 | 25 | Swoole底层实现协程调度, **业务层无需感知**, 开发者可以无感知的**用同步的代码编写方式达到异步IO的效果和超高性能**，避免了传统异步回调所带来的离散的代码逻辑和陷入多层回调中导致代码无法维护. 26 | 27 | 需要在`onRequet`, `onReceive`, `onConnect`等事件回调函数中使用, 或是使用go关键字包裹 (`swoole.use_shortname`默认开启). 28 | 29 |
30 | 31 | ## 例子 32 | 33 | > 由于PDO使用了多引擎, PHP层面难以用类实现构造函数返回不同的实例. 34 | 35 | 除了构造函数有所不同, 其它使用方法完全一样 36 | 37 | #### query 38 | 39 | ```php 40 | $options = [ 41 | 'mysql:host=127.0.0.1;dbname=test;charset=UTF8', 42 | 'root', 43 | 'root' 44 | ]; 45 | $sql = 'select * from `user` LIMIT 1'; 46 | 47 | //PDO 48 | $pdo = new \PDO(...$options); 49 | $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); //strong type 50 | $pdo_both = $pdo->query($sql)->fetch(); 51 | $pdo_assoc = $pdo->query($sql)->fetch(\PDO::FETCH_ASSOC); 52 | $pdo_object = $pdo->query($sql)->fetch(\PDO::FETCH_OBJ); 53 | $pdo_number = $pdo->query($sql)->fetch(\PDO::FETCH_NUM); 54 | 55 | //SwPDO 56 | $swpdo = SwPDO::construct(...$options); //default is strong type 57 | $swpdo_both = $swpdo->query($sql)->fetch(); 58 | $swpdo_assoc = $swpdo->query($sql)->fetch(\PDO::FETCH_ASSOC); 59 | $swpdo_object = $swpdo->query($sql)->fetch(\PDO::FETCH_OBJ); 60 | $swpdo_number = $swpdo->query($sql)->fetch(\PDO::FETCH_NUM); 61 | 62 | var_dump($pdo_both === $swpdo_both); 63 | var_dump($pdo_assoc === $swpdo_assoc); 64 | var_dump($pdo_object == $swpdo_object); 65 | var_dump($pdo_number === $swpdo_number); 66 | //output: true true true true 67 | ``` 68 | 69 | #### prepare 70 | 71 | ```php 72 | //PDO 73 | $pdo = new \PDO(...$options); 74 | $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); //strong type 75 | $statement = $pdo->prepare($sql); 76 | $statement->execute(); 77 | $pdo_fetch = $statement->fetch(\PDO::FETCH_ASSOC); 78 | $statement->execute(); 79 | $pdo_fetch_all = $statement->fetchAll(); 80 | $statement->execute(); 81 | $pdo_fetch_all_column = $statement->fetchAll(\PDO::FETCH_COLUMN, 1); 82 | $statement->execute(); 83 | $pdo_fetch_column = $statement->fetchColumn(); 84 | $statement->execute(); 85 | 86 | //SwPDO 87 | $swpdo = SwPDO::construct(...$options); 88 | $statement = $swpdo->prepare($sql); 89 | $statement->execute(); 90 | $swpdo_fetch = $statement->fetch(\PDO::FETCH_ASSOC); 91 | $statement->execute(); 92 | $swpdo_fetch_all = $statement->fetchAll(); 93 | $statement->execute(); 94 | $swpdo_fetch_all_column = $statement->fetchAll(\PDO::FETCH_COLUMN, 1); 95 | $statement->execute(); 96 | $swpdo_fetch_column = $statement->fetchColumn(); 97 | $statement->execute(); 98 | 99 | var_dump($pdo_fetch === $swpdo_fetch); //true 100 | var_dump($pdo_fetch_all === $swpdo_fetch_all); //true 101 | var_dump($pdo_fetch_all_column === $swpdo_fetch_all_column); //true 102 | var_dump($pdo_fetch_column === $swpdo_fetch_column); //true 103 | ``` 104 | 105 | ### bind 106 | 107 | ```php 108 | //PDO 109 | $pdo = new \PDO(...$options); 110 | $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); //strong type 111 | $statement = $pdo->prepare($sql); 112 | $statement->execute(['id' => 1]); 113 | $pdo_bind_exec = $statement->fetch(\PDO::FETCH_ASSOC); 114 | 115 | $statement->bindValue(':id', 1); 116 | $statement->execute(); 117 | $pdo_bind_val = $statement->fetch(\PDO::FETCH_ASSOC); 118 | 119 | $statement->bindParam(':id', $id); 120 | $statement->execute(); 121 | $pdo_bind_param = $statement->fetch(\PDO::FETCH_ASSOC); 122 | 123 | //SwPDO 124 | $swpdo = SwPDO::construct(...$options); 125 | $statement = $swpdo->prepare($sql); 126 | $statement->execute(['id' => 1]); 127 | $swpdo_bind_exec = $statement->fetch(\PDO::FETCH_ASSOC); 128 | 129 | $statement->bindValue(':id', 1); 130 | $statement->execute(); 131 | $swpdo_bind_val = $statement->fetch(\PDO::FETCH_ASSOC); 132 | 133 | $statement->bindParam(':id', $id); 134 | $statement->execute(); 135 | $swpdo_bind_param = $statement->fetch(\PDO::FETCH_ASSOC); 136 | 137 | var_dump($pdo_bind_exec === $swpdo_bind_exec); //true 138 | var_dump($pdo_bind_val === $swpdo_bind_val); //true 139 | var_dump($pdo_bind_param === $swpdo_bind_param); //true 140 | ``` 141 | 142 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # SwPDO 2 | 3 | [![Latest Version](https://img.shields.io/github/release/swlib/swpdo.svg?style=flat-square)](https://github.com/swlib/swpdo/releases) 4 | [![Build Status](https://travis-ci.org/swlib/swpdo.svg?branch=master)](https://github.com/swlib/swpdo/releases) 5 | [![Php Version](https://img.shields.io/badge/php-%3E=7.1-brightgreen.svg?maxAge=2592000)](https://secure.php.net/) 6 | [![Swoole Version](https://img.shields.io/badge/swoole-%3E=2.1.2-brightgreen.svg?maxAge=2592000)](https://github.com/swoole/swoole-src) 7 | [![SwPDO License](https://img.shields.io/hexpm/l/plug.svg?maxAge=2592000)](https://github.com/swlib/swpdo/blob/master/LICENSE) 8 | 9 | ## Introduction 10 | 11 | Traditional PDO to Swoole Coroutine migration plan without cost. 12 | 13 | [中文文档](README-zh.md) 14 | 15 | ## Install 16 | 17 | The best way to install: [Composer](http://getcomposer.org/) : 18 | 19 | ```shell 20 | composer require swlib/swpdo 21 | ``` 22 | 23 |
24 | 25 | ## Coroutine 26 | 27 | The bottom layer of Swoole implements coroutine scheduling, **and the business layer does not need to be aware**. Developers can use synchronization code writing methods to achieve the effect and ultra-high performance of asynchronous IO without perception, avoiding the discrete code logic and trapping caused by traditional asynchronous callbacks. Too many callback layers causes the code too difficult to maintain. 28 | 29 | It needs to be used in event callback functions such as `onRequet`, `onReceive`, and `onConnect`, or wrapped using the go keyword (`swoole.use_shortname` is on by default). 30 | 31 |
32 | 33 | ## Example 34 | 35 | > Because PDO uses multiple engines, it is difficult at the PHP level to return different instances with class - implemented constructors. 36 | 37 | **Except that the constructor is different, all methods use in the same way.** 38 | 39 | #### query 40 | 41 | ```php 42 | $options = [ 43 | 'mysql:host=127.0.0.1;dbname=test;charset=UTF8', 44 | 'root', 45 | 'root' 46 | ];

53 | $pdo_assoc = $pdo->query($sql)->fetch(\PDO::FETCH_ASSOC); 54 | $pdo_object = $pdo->query($sql)->fetch(\PDO::FETCH_OBJ); 55 | $pdo_number = $pdo->query($sql)->fetch(\PDO::FETCH_NUM); 56 | 57 | //SwPDO 58 | $swpdo = SwPDO::construct(...$options);

67 | var_dump($pdo_number === $swpdo_number); 68 | //output: true true true true 69 | ``` 70 | 71 | #### prepare 72 | 73 | ```php 74 | //PDO 75 | $pdo = new \PDO(...$options); 76 | $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
