我想為對(duì)象設(shè)置許多JSON數(shù)據(jù)，但我不想寫很多設(shè)置方法。例：//(POST : JSON DATA) JSON keys equals entity variable names{"data1": "banana","data2": "index, follow","data3": "true","data4": "abcdef","data5": "false","big_data1": "lorem ipsum ....""name": "apple" ....}我的實(shí)體（簡(jiǎn)短版）class Category{ //.... private $data1; public setData1(string $data1): self{ $this->data1 = $data1; return $this; } public getData1():string{ return $this->data1; } //...}我的控制器//...public function index(){ //post data json to object $data = json_decode($postdata); # data object $category = new Category(); # new category class $object = new \ReflectionObject($category); /** What is the next step? $this->setData1($data->data1); $this->setData2($data->data2); if(!empty($data->big_data12) $this->setBigData12($data->big_data12) . . . $this->setData12($data->data12) */}如何做一個(gè)簡(jiǎn)單的方法？如何避免編寫許多集合方法？

根本不需要使用反射。你可以使用神奇的方法。具體說來。文檔。_call()
一個(gè)非常簡(jiǎn)單、幼稚的實(shí)現(xiàn)：
class Category
{
private $data1;
private $data2;
private $data3;
private $bigData12;
public function __call($method, array $arguments)
{
$verb = substr($method, 0, 3);
$noun = lcfirst(substr($method, 3));
if (!property_exists($this, $noun)) {
throw new Exception('Property does not exist');
}
switch($verb) {
case 'set':
$this->$noun = $arguments[0];
return $this;
case 'get':
return $this->$noun;
}
}
}
$cat = new Category();
$cat->setData1('hello')
->setData2('hola')
->setData3(12345)
->setBigData12('hello world');
echo $cat->getData1(), "\n";
echo $cat->getData2(), "\n";
echo $cat->getData3(), "\n";
echo $cat->getBigData12(), "\n";
你可以在這里看到它的工作原理。
請(qǐng)注意，我不建議這樣做太多。這種事情非常容易出錯(cuò)，不能被類型暗示，收益從微不足道到根本不存在。
