this is my code in php

// $apiResults['participants'] == first array
// $apiResults['conference_participants'] == second array


$conf_participants = array();
      foreach($apiResults['participants'] as $participant)
      {
       foreach($apiResults['conference_participants'] as $conference_participant)
         {
    if($participant['calleridnum'] == $conference_participant['uid'])
        {

           $conf_participants['uniqueid'] = $participant['uniqueid'];
           $conf_participants['event'] = $participant['event'];
           $conf_participants['channel'] = $participant['channel'];
           $conf_participants['uid'] = $conference_participant['uid'];



       }
       }
      }

Answer 1

lets say you have two arrays of objects arr1 and arr2 You need to loop through both, compare the value calleridnum from arr1 and uid from arr2 if they are same then merge the object in arr1 .

for(var i in arr1){
for (var j in arr2)
   if (arr2[j].uid == arr1[i].calleridnum ) {
    $.extend(arr1[i], arr2[j]);
       break;
   }
}
