Adding Php Code to Header

[TRABZONLUKAPLAN]

Hi,

I am trying to write some scripting and the first step is like below but it throws an exception. What I am doing wrong ? Isnt possible to create session there ?

I added this to Header

if(isset($_SESSION['FirstAccess']) && ((time() - $_SESSION['FirstAccess']) < 30)))
{

}
else
{
$_SESSION['FirstAccess'] = time();
}

It says

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/bilge61/public_html/forum/includes/adminfunctions_template.php(3950) : eval()'d code on line 5

You have one too many )'s at the end of that first 'if' line
