Answer 1

I think you are not seeing that when you do this:
$array[] = array('id' => $row->id);
You are assigning an array, inside another array, and the implode function is expecting an array of values, and not an array of array with values.
The answer is that you should do this
foreach ($sql->result() AS $row){
$array = array('id' => $row->id);
$implode = IMPLODE(',',$array);
}
Instead of this
foreach ($sql->result() AS $row){
$array[] = array('id' => $row->id);
$implode = IMPLODE(',',$array);
}
And the reason is that implode function firm is
string implode ( string $glue , array $strings )
Hope it helps!

try this, the simple code without implode and array
$sql = $this->db->query('select * from TEST');
$val = '';
foreach ($sql->result() AS $row){
$val .= $row->id.',';
}
// before rtrim $val is 1,2,3,
$val = rtrim($val,',');
// after rtrim $val is 1,2,3
$query = $this->db->query("SELECT * FROM TEST WHERE id IN('".$val."')");
// finally query will be "SELECT * FROM TEST WHERE id IN('1,2,3')"
may it can help you

Answer 3

You are setting an array inside an array. $array[] = means create a new key in $array and put everything after the equal sign into that key. So you don't have to create a new array.
It is simple as this $array[] = $row->id.
Then $array[0] would be the first id that is in the database and so on.

The problem solved I'm using query like bellow. Thanks all for response.
$sql = $this->db->query('select * from TEST');
foreach ($sql->result() AS $row){
$array[] = array('id' => $row->id);
}
$query = $db2->query("SELECT * FROM mCIF WHERE nocif IN ('".implode("','",$array)."')");
$result = array();
foreach($query->result_array() AS $row){
$result[] = array (
'id' => $row['id'],
'nm' => $row['nm'],
'golcust' => $row['golcust'],
'golcustbi' => $row['golcustbi'],
'jnsbh' => $row['jnsbh']
);
}
$this->db->insert_batch('test3',$result);
