weird PHP-prob

[Nezzar]

What does this mean:
Fatal error: Cannot redeclare getdate() in f:\web\phoop\_global.php on line 14

I didn't declare any other function with this name anywhere else or even declared function similar to this one. So where's the problem?
I don't think that it is necessary but here's the code for the function:

PHP Code:

function getDate() {
    $year = date(Y);
    $month = date(m);
    $day = date(d);
    $date = $year."-".$month."-".$day;
    return $date;
};

No more help needed. I just renamed the function and it works fine now.
