suppress error messages.

so my guess it's not working, its just not reporting an error.

@ will hide the error if any (will not display it on the page), don't understand why it will make the function work or not though.

Actually, putting @ in front of function only suppresses any error messages if some would occur.

@ in PHP is Error Control Operators

before PHP 5 , this is useful for exceptions handling function
 PHP 5 provided the try... catch

ah,.. ok... i did not actually TEST it to make sure it was working.  No error and I assumed it was working.... basically what I am trying to do is session_destroy() but I got this error:

Warning: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session in /home/advanc8/public_html/chpcomputers/admin/index.php on line 2

I read somewhere else to put the @ in front of session_destroy() but obviously that does not fix the problem.  Ideas?

you need to add
session_start(); before session_destroy();
