Session Start error

[qadeer_ahmad]

Hi,
I a project file i am using session_start() and i see this error

Notice: A session had already been started - ignoring session_start() in c:\inetpub\wwwroot\pfg\admintask.php on line 2

its working all okey but i don't want to see this message can we skip this error message or
Is thier way we can check before that session is already start or not as if i remove this (session_start()) i does't get session value's .

if (!isset(session_id())) {
  session_start();
}

Parse error: parse error, expecting T_VARIABLE' or'$'' in c:\inetpub\wwwroot\pfg\admintask.php on line 2

there isn't an error in that code.

actually, there might be. we need to get rid of the isset. isset checks variables while session_id is some sort of function. try;

if (!session_id()) {
  session_start();
}
