title: Manual Transaction in CodeIgniter
body: <p>I'm trying to use Codeigniter transactions and as I am new to it, I really don't know to use <code>$this-&gt;db-&gt;trans_begin()</code> or $<code>this-&gt;db-&gt;trans_start().</code> </p>
  
  <p>What are manual transactions and when should we consider it to be used. </p>
  
  <p>And once the transaction is committed, should <code>$this-&gt;db-&gt;trans_off()</code> be used every time to continue auto-commit?</p>
