今天碰到一個(gè)需求是需要自己關(guān)聯(lián)自己,輸出數(shù)據(jù)為樹(shù)狀,我們?cè)诙x關(guān)聯(lián)關(guān)系的用get_calss方法

/*** 定義關(guān)聯(lián)關(guān)系* @return \think\model\relation\HasMany*/public function user(){return $this->hasMany(get_class($this),'area','area');} {"code": 200,"message": "成功","data": [{"area": "自營(yíng)","user": [{"id": 2,"usr": "毅拓科貿(mào)","area": "自營(yíng)"},{"id": 3,"usr": "安博","area": "自營(yíng)"},{"id": 4,"usr": "世紀(jì)揚(yáng)天","area": "自營(yíng)"},{"id": 5,"usr": "滄田","area": "自營(yíng)"},{"id": 6,"usr": "佳陽(yáng)電子","area": "自營(yíng)"},{"id": 7,"usr": "博中天虹","area": "自營(yíng)"},{"id": 8,"usr": "丹靈","area": "自營(yíng)"},{"id": 153,"usr": "中美隆","area": "自營(yíng)"},{"id": 154,"usr": "格力","area": "自營(yíng)"},{"id": 155,"usr": "美承","area": "自營(yíng)"}]},{"area": "安陽(yáng)","user": [{"id": 9,"usr": "安陽(yáng)A","area": "安陽(yáng)"},{"id": 27,"usr": "安陽(yáng)B","area": "安陽(yáng)"},{"id": 59,"usr": "林州市","area": "安陽(yáng)"},{"id": 62,"usr": "安陽(yáng)縣","area": "安陽(yáng)"},{"id": 82,"usr": "滑 縣","area": "安陽(yáng)"},{"id": 113,"usr": "內(nèi)黃縣","area": "安陽(yáng)"},{"id": 119,"usr": "湯陰縣","area": "安陽(yáng)"}]},

這里的get_class($this):獲取的是當(dāng)前類(lèi)名

get_called_calss和它不同,是調(diào)用該方法的類(lèi)名(和self,static和區(qū)別都是在繼承上).
