Calling Stored Procedure inside foreach PHP Codeigniter - php

Question

I'm having an error when calling stored procedure inside foreach
It says "Commands out of sync you can't run this command now" .
I already looking for solution, but the result is not like i'm expecting.
This is my code
$query = "CALL PROCEDURE_HEAD()";
$sql = $this->db->query($query)->result_array();
foreach($sql as $key) {
$name = $key['name'];
$array['name'] = $name;
$array['data'] = $key['data'];
$query2 = "CALL PROCEDURE_CHILD('$name')";
$sql2 = $this->db->query($query2)->result_array();
foreach($sql2 as $value) {
$array['child'] = array(
'child_name' => $value['child_name'],
'child_data' => $value['child_data']
);
}
}
i have tried run codeigniter : Commands out of sync; you can't run this command now, and because i'm using Procedure after Procedure,it doesn't run.
Any kind of help is really appreciated

Use Model with associate this
In Controller
$head = $this->Model_name->call_head();
foreach($head as $item) {
$name = $item['name'];
$array['name'] = $name;
$array['data'] = $item['data'];
$child = $this->Model_name->call_child($name);
foreach($child as $value) {
$array['child'] = array(
'child_name' => $value['child_name'],
'child_data' => $value['child_data']
);
}
}
In model
public function call_head()
{
$query = "CALL PROCEDURE_HEAD()";
$result = $this->db->query($query)->result_array();
$query->next_result();
$query->free_result();
return $result;
}
public function call_child($name)
{
$query = "CALL PROCEDURE_CHILD($name)";
$result = $this->db->query($query)->result_array();
$query->next_result();
$query->free_result();
return $result;
}
