I think this is a dumb question but I could not find it on php. Why is a + with the = in the following code:
function calculateRanking()
{
$created = $this->getCreated();
$diff = $this->getTimeDifference($created, date('F d, Y h:i:s A'));
$time = $diff['days'] * 24;
$time += $diff['hours'];
$time += ($diff['minutes'] / 60);
$time += (($diff['seconds'] / 60)/60);
$base = $time + 2;
$this->ranking = ($this->points - 1) / pow($base, 1.5);
$this->save();
}
Is this so $time has all those values or rather it is adding all the values to $time?
Thanks

It's adding all those values to time.
something += somethingelse
is a shortcut for
something = something + somethingelse
