session_start() this will be added on top of page if u dont then use @session_start();

Answer 2

The error messages mean that you have called session_start() after the &lt;HEAD&gt;&lt;/HEAD&gt; element of the HTML page. You cannot do this because &lt;/HEAD&gt; causes the headersto be sent to the output buffer, and session_start() needs to be able to write header information. You need to move the code.
