how to get last id after insert db in php - php

Question

here I save data to the database with multiple rows, I want to retrieve each last id per row, how do I do that?
ex : print_r result when input data.
Array
(
[0] => Array
(
[name] => metode 11
[description] => DESC 1
)
[1] => Array
(
[name] => metode 22
[description] => DESC 2
)
[2] => Array
(
[name] => metode 33
[description] => DESC 1
)
)
in database
id | name | description
1 metode 11 desc 1
2 metode 22 desc 2
3 metode 33 desc 3
after finished input I want to take each id
and this my code
$data = array();
$numrow = 1;
foreach ($sheet as $row) {
if ($numrow > 1) {
array_push($data, array(
'name' => $row['A'],
'description' => $row['B'],
));
}
$numrow++;
}
$this->db->insert_batch('my_tabel', $data);
$myid =$this->db->insert_id();
//after insert i retrieve id using last_id() function, however, only last id is fetched, i want to fetch each id
$data_1 = array();
$numrow2 = 1;
foreach ($sheet as $row) {
if ($numrow2 > 1) {
array_push($data_1, array(
'id_last' => $myid,
'id' => $row['E'],
'barang' => $row['F'],
));
}
$numrow2++;
}
i want like this :
Array
(
[0] => Array
(
[last_id] => 1
[id] => 33
[barang] => ccc
)
[1] => Array
(
[last_id] => 2
[id] => 44
[barang] => dd
)
[2] => Array
(
[last_id] => 3
[id] => 55
[barang] => eee
)
)
thanks in advance for those who have answered
I hope what I said was clear enough

Answer 1

Why not insert it row by row instead of a batch?
Build a dictionary from each insert to pair it back later on.
$data = array();
$numrow = 1;
foreach ($sheet as $row) {
if ($numrow > 1) {
array_push($data, array(
'name' => $row['A'],
'description' => $row['B'],
));
}
$numrow++;
}
$array_of_insert_id = array();
foreach ($data as $index => $data_to_insert) {
$this->db->insert('my_tabel', $data_to_insert);
$array_of_insert_id[$index] = $this->db->insert_id();
}
$data_1 = array();
$numrow2 = 1;
$counter = 0;
foreach ($sheet as $row) {
if ($numrow2 > 1) {
array_push($data_1, array(
'id_last' => $array_of_insert_id[$counter],
'id' => $row['E'],
'barang' => $row['F'],
));
}
$numrow2++;
$counter++;
}

//table field with input field data array
$table_data = [
'table_field1' => $input_data1,
'table_field2' => $input_data2,
];
//insert data in database
$this->db->insert('table_name',$table_data);
//after insert return id
return $inserted_id = $this->db->insert_id();
