PHP overwrite array mysql query? - php

Question

i have this code and i want to return an array of object and inside that object an associative array.
something like this
[
{"ids":["id1",'id2','id3'],
"item":["name","name2","name3"]},
{"ids":["id4",'id5','id6'],
"item":["name4","name5","name6"]},
{"ids":["id1114",'id1115','id1116'],
"item":["name11114","name11115","name1116"]},
]
it sends the objects with the array but it only has the last element in the array
//get customers of single item
if($this->connect()->connect_error){
echo die("Connection failed: " . $this->connect()->connect_error);
}else{
for($i=0; $i<count($final_array['item']); $i++){
$single = $final_array['item'][$i];
$sql = "SELECT ACCT_ID, PARTS_EXPIRY, dcii_item, dcii_desc, dcii_acct_id, dcii_qty AS QTY
FROM dos_account AS DOS
JOIN dos_client_invoice_items as DOS2
ON DOS.ACCT_ID = DOS2.dcii_acct_id
WHERE dcii_item = '$single'
AND DOS.PARTS_EXPIRY BETWEEN '$start' AND '$end'
ORDER BY DOS.PARTS_EXPIRY";
$result = $this->connect()->query($sql);
$numRows = $result->num_rows;
if($numRows > 0){
// $array_container = [];
while($row = $result->fetch_assoc()){
$item[] = $row['dcii_item'];
$acctID[] = $row['ACCT_ID'];
$array_container5 = array();
$array_container5[] = $row['dcii_item'];
$array_container = array();
$array_container[] = $row['ACCT_ID'];
//array_push($array_container, $row['dcii_item']);
}
$array_container2['item'] = $array_container5;
$array_container2['ids'] = $array_container;
$final_array['objectContainer'][] = $array_container2;
}
}
$jsonData = json_encode($final_array);
echo $jsonData;
}
