JSON parsing problem for PHP

{"type": "Success", "code": 0, "message": null, "Data": {"box_list": [{"Boxid": "Cfce938f2c7c11e69d5700000a00191c", " Boxnum ":" Nantong_test1 "," Boxname ":" My Safe "," BOXIP ":" "," Boxmac ":" "," Powerstatus ":" 0 "," networkstatus ":" 0 "," Doorstatus ":" 2 "," Shakeinfo ":" 1 "," Devicestatus ":" 1 "," Boxstatus ":" 1 "," Verifystatus ":" "," lockpwd ":" abcd07033132333435363f030d "," Boxversion ": 0," Channelid ":" Nantong_test1 "," Boxcontrolpwd ":" 874d05d4bdd9077a7aefa0dc8c8cbd1f "," Adminuserid ":" 62f199be303b11e684c000000a00191c "," BoxPhone ":" "," DefaultSkin " : "0", "networkname": "", "Agentid": "", "createtime": null, "Warninhcount": 0, "batterylevel": null, "temp": null},{"Boxid ":" 73b1a2932c7211e69d5700000a00191c "," Boxnum ":" Lvlei6 "," Boxname ":" My Safe "," BOXIP ":" "," Boxmac ":" "," Powerstatus ": "0", "networkstatus": "0", "doorstatus": "2", "Shakeinfo": "1", "Devicestatus": "1", "Boxstatus": "1", "Verifystatus": "", "Lockpwd": "abcd07033132333435363f030d", "boxversion": +, "Channelid": "Lvlei6", "Boxcontrolpwd": " 874d05d4bdd9077a7aefa0dc8c8cbd1f "," Adminuserid ":" 31f674062c8311e69d5700000a00191c "," Boxphone ":" "," Defaultskin ":" 0 "," networkname ":" "," Agentid ":" "," createtime ": null," Warninhcount ": 0," Batterylevel ": null," temp ": null}]," user ": {" id ":" 296d4ecc303d11e684c000000a00191c "," UserName ":" Kaka "," LoginName " : "12@qq.com", "loginpwd": "874d05d4bdd9077a7aefa0dc8c8cbd1f", "UserFinger1": "", "UserFinger2": "", "UserFinger3": "", "Type": "0", "Userphone": "", "Userphoto": "http://hissdata.blob.core.chinacloudapi.cn/userpicdata/ 296d4ecc303d11e684c000000a00191c_1465717285898.png "," Channelid ":" "," userlistendate ": 1465694992000," BoxNum ":" ", "Controlpwd": "", "Usernum": "", "useraddress": "", "Usermail": "12@qq.com"}}

To get the data under all subscripts in the box_list,
The way I get $c = $data [' Data '] [' box_list '][0][' Boxid ']; However, I do not know why the 73b1a2932c7211e69d5700000a00191c is the boxid of the box_list subscript 1. can only get this.

No problem, you print out the parsed array to check
