не выводит из масива

вот у меня есть такой api код
{"status":"OK","online":1,"data":{"b":{"type":"mta ","ip":"46.174.50.48","c_port":22374,"q_port":2237 4,"s_port":22374,"status":1},"s":{"game":"mta","na me":"Fuck The Clearance[vk.com\/fuckclearance_mta] DRIFT,STANCE,TimeAttack,Rally,JDM Culture","map":"Japan","players":15,"playersmax":5 0,"password":0},"e":{"gamename":"mta","hostport":" 22251","gamemode":"FTC Drive","version":"1.3"},"p":[{"name":"sanek","score":"","ping":"181"},{"name":" |EvilEmpire|Sanchez","score":"","ping":"44"},{"nam e":"#Darius","score":"","ping":"27"},{"name":"[#most_od]Striga","score":"","ping":"32"},{"name":"Whisperin gHail24","score":"","ping":"73"},{"name":"KiT","sc ore":"","ping":"21"},{"name":"HARDCORE","score":"" ,"ping":"23"},{"name":"SkyJoker","score":"","ping" :"26"},{"name":"[\/\/\/M]Jerker","score":"","ping":"6"},{"name":"[T.Factory]#Max","score":"","ping":"57"},{"name":"Vano_Google ","score":"","ping":"67"},{"name":"Bula?","score": "","ping":"70"},{"name":"SL1CK","score":"","ping": "12"},{"name":"Soulja_Wayne","score":"","ping":"44 "},{"name":"[EE]GEOMORF","score":"","ping":"59"}]}}

вывожу с него в label
$arr = json_decode($file, true);
c("label1")->text = "IP ".$arr[data][b][ip]." : ".$arr[data][e][hostport];
c("label2")->text = "Gamemode ".$arr[data][e][gamemode];
c("label3")->text = "Версия ".$arr[data][e][version];

а вот почему вот это не хочет выводить?
c("label4")->text = "Карта ".$arr[data][s][map];
