$this->uri->assoc_to_uri()
建立一個關連式陣列來作為輸端並且產生 URI 字串的格式
$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');
$str = $this->uri->assoc_to_uri($array);

=================
顯示結果陣列
=================
$sql = "SQL詢查字串";
$query = $this->db->query($sql);
foreach ($query->result_array() as $row)
{
echo $row['title'];
echo $row['name'];
echo $row['body'];
}
=================
顯示結果陣列並判斷是否有資料
=================

 
//刪除大於一小時 3600秒
$this->db->query('DELETE FROM ci_sessions WHERE timestamp < (UNIX_TIMESTAMP() - 3600)');
$this->db->query('OPTIMIZE TABLE ci_sessions');

===================
設定session數據
===================
$this - > session - > set_userdata('變數','值');
===================
讀取session數據

$_SESSION['item']
或
$this - > session - > item
