any idea , snippet code ?

try code.

function combo($array1, $array2) {     foreach($array1 $key => $value) {         if(isset($array2[$key]))         $result[$key] = array_merge($value, $array2[$key]);         else         $result[$key] = $value;     }     return $result; } $array = combo(#your array 1#, #your array 2#); print_r($array); // view output 

updated code

function combo($array1, $array2) {     foreach($array1 $key => $value) {         if(isset($array2[$key])) {         if($value['uregisterdate'] == $array2[$key]['uregisterdate'])            {             $result[$key] = array_merge($value, $array2[$key]);             }              else             {                 $result[$key] = $array2[$key];                 $result[rand(0,99)]= $value;             }          }         else         $result[$key] = $value;     }     return array_values($result); } $array = combo($a1, $a2); print_r($array);
