A session had already been started - ignoring session_start()

[anujgarg]

Hi,

 

I am getting above said error. I have tried the following but no use:

 

if(!isset($_SESSION))

{

}

else

{

session_start();

}

 

and

 

if(!isset(session_id()))

{

}

else

{

session_start();

}

 

Please help...

 

TIA

Hi anujgarg,

 

This error normally appears if you are including the same file multiple times on a page, or if a file you're including also has a session_start() statement in it.

 

Hope this helps.

Bricktop, to be descriptive, I am using CodeIgniter and have the statement session_start() at the bottom of the file config.php.

Yes, you are right, this file is being included multiple times on a page.

 

Please let me know what is the solution to get rid of this error.

 

TIA

Hi anujgarg,

 

You could simply use @session_start(), the @ would suppress the error but obviously there is still an error occuring and this isn't ideal.

 

if(!isset($_SESSION)) is the correct syntax to use when checking if a session has been started.  Try amending the code in your config.php to be:

 

if(!isset($_SESSION))
{
session_start();
}

 

Then the session will only start if it hasn't already been started.

 

Hope this helps.

Remember to use die(); and echo when debugging a script, youll locate the error 10 times as fast

 

if(!isset($_SESSION)){

session_start();
}

echo session_id();
die();

//rest of script below....
