ขอคำแนะนำ sql array หน่อยครับ ผมลองทำแล้วมี error ครับ

<?php 
include("config_mysqli.php");


$sql = "SELECT data_user.*,data_car.*,data_prb.*,data_ins.*,money_all.*
FROM data_user 

left JOIN data_car on data_user.id=data_car.id
left JOIN data_prb on data_user.id=data_prb.id
left join data_ins on data_user.id=data_ins.id
left join money_all on data_user.id=money_all.id
 
WHERE data_user.id = '33943' or data_user.id = '33944'  ";

$query = $conn->query($sql) or die($conn->error."<br>$sql");
$num = $query->num_rows();
$resultArray = array();
for ($i = 0;$i<$num;$i++) {
	$result = $query->fetch_array();
	array_push($resultArray,$result);
}

$resultArray = ['phone'];
print_r($resultArray);


//$d = date("Y-m-d");
//$dump = date("Y-m-d",strtotime("+10 day"));

?>
