Answer 1

You can use this loop:
foreach($ar as $k1=>$a1){
foreach($ar as $k2=>$a2){
if($k1 < $k2 && $a1["DriverLocation"]["driver_id"] == $a2["DriverLocation"]["driver_id"]){
$ar[$k1]["ZipCode"][] = $a2["ZipCode"];
if(isset($ar[$k1]["ZipCode"]["id"])){
$ar[$k1]["ZipCode"][] = array("id"=>$ar[$k1]["ZipCode"]["id"]);
unset($ar[$k1]["ZipCode"]["id"]);
}
unset($ar[$k2]);
}
}
}

Answer 2

Use array_push() function to make it
for sample example
<?php
$a=array("red","green");
array_push($a,"blue","yellow");
print_r($a);
?>
output
Array ( [0] => red [1] => green [2] => blue [3] => yellow )
