SplBean

用途

用于定义表结构，过滤掉无效字段数据。

如何使用

  1. <?php

  9. require './vendor/autoload.php';
  11. class Apple extends \EasySwoole\Spl\SplBean {
  12.     protected $name;
  13.     protected $price;
  14.     protected $number;
  16.     protected function setKeyMapping(): array
  17.     {
  18.         return ['price' => 'as'];
  19.     }
  20. }
  22. $apple = new Apple(['name' => 'test', 'price' => 12, 'number' => 12, 'age' => 2], true);
  23. print_r($apple->toArray());
  24. print_r($apple->toArrayWithMapping());
  25. echo '---------------------------------------'.PHP_EOL;
  26. $apple->restore(['name' => 'blank', 'price' => 12, 'number' => 12]);
  27. print_r($apple->toArray());
  28. print_r($apple->toArrayWithMapping());
  30. /**

核心对象方法

核心类：EasySwoole\Spl\SplBean。

__construct

构造函数，初始化bean数据

  • array $data 数据
  • mixed $autoCreateProperty 是否过滤非类成员变量成员数据

public function __construct(array $data = null,$autoCreateProperty = false)

allProperty

获取类所有的public和protected 成员变量

final public function allProperty()

toArray

过滤并转换程数组数据

  • array $columns 要过滤的字段数据
  • mixed $filter 过滤满足某种条件的数据

function toArray(array $columns = null,$filter = null)

toArrayWithMapping

获取过滤后带有字段别名的数组数据

  • array $columns 要过滤的字段数据
  • mixed $filter 过滤满足某种条件的数据

function toArrayWithMapping(array $columns = null,$filter = null)

arrayToBean

设置类属性

  • array $data 数据
  • mixed $autoCreateProperty 是否创建非类成员变量

final private function arrayToBean(array $data,$autoCreateProperty = false):SplBean

addProperty

设置类成员变量

  • mixed $name 成员变量名字
  • mixed $value 成员变量值

final public function addProperty($name,$value = null):void

getProperty

获取类成员变量值

  • mixed $name 成员变量名字

final public function getProperty($name)

jsonSerialize

获取类成员变量集合

final public function jsonSerialize():array

initialize

初始化操作

protected function initialize()

setKeyMapping

设置keyMapping关系，也就是字段别名

protected function setKeyMapping()

setClassMapping

设置classMapping关系，也就是关联类

protected function setClassMapping()

restore

重新初始化bean数据

  • array $data 数据
  • mixed $autoCreateProperty 是否过滤非类成员变量成员数据

public function restore(array $data = [], $autoCreateProperty = false)

classMap

绑定关联类

private function classMap()
