how to cek array php - php

Question

I have an array that I will insert into the item table, here I use multiple inserts
Array
(
[0] => Array
(
[id_service] => 2
[tracking_number] => RJC219384044389234035
)
[1] => Array
(
[id_service] => 1
[tracking_number] => RJC749944771469498146
)
)
in the item table, there is already id_service: 2
how to make validation, when one of the input is already in the item table, then all the input is false so it fails?
my code
public function nyobain()
{
$resi = $this->input->post('kode'); //tracking_number
$expld = explode(' ', $resi);
$data = $this->M_outbound_destinasi->dbGet($expld); //get 'id_service' where tracking_number
// $db = $this->db->query("SELECT id_service FROM `tabel_items`")->result();
// foreach ($db $key) {
// $temp=array($key->id_service);
// }
// how to cek ? if id_service already in the item table
foreach ($data as $key) {
$idnya = $key['id_service'];
$id_outbound = $key['id_outbound'];
$id_indes = $key['id_indes'];
$id_outbag = $key['id_outbag'];
$data_insert = array(
'jenis' => 'outbound-destinasi',
'id_service' => $idnya,
'id_indes' => $id_indes,
'id_outbound' => $id_outbound,
'id_outbag' => $id_outbag,
'id_admin' => $this->session->userdata('ses_id')
);
$this->db->insert('tabel_items', $data_insert);
}
echo json_encode($data);
}

You can use in_array to achieve this
public function nyobain(){
$resi = $this->input->post('kode');
$expld = explode(' ', $resi);
$data = $this->M_outbound_destinasi->dbGet($expld);
$db = $this->db->query("SELECT id_service FROM `tabel_items`")->result();
if(isset($data) && $data !== ''){//check if $data has a value and it not null
if (in_array($data ,$db, true)) {
return $data.'already exists in the DB!';
}else{
foreach ($data as $key) {
$idnya = $key['id_service'];
$id_outbound = $key['id_outbound'];
$id_indes = $key['id_indes'];
$id_outbag = $key['id_outbag'];
$data_insert = [
'jenis' => 'outbound-destinasi',
'id_service' => $idnya,
'id_indes' => $id_indes,
'id_outbound' => $id_outbound,
'id_outbag' => $id_outbag,
'id_admin' => $this->session->userdata('ses_id')
];
$this->db->insert('tabel_items', $data_insert);
}
return json_encode($data);
}
}
}
