Question

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
