Question

I got an array that outputs data into an xml. It looks like this:

        $data = array(
            'trip_id'      => $this->trip_id,
            'from'         => $this->from,
            'from_lat'     => $this->from_lat,
            'from_lon'     => $this->from_lon,
            'to'           => $this->to,
            'to_lat'       => $this->to_lat,
            'to_lon'       => $this->to_lon,
            'when'         => $this->when,
            'when_iso'     => date('Y-m-d H:i', $this->when),
            'details'      => $this->details,
            'got_car'      => $this->got_car,
            'inserted'     => $this->inserted,
            'name'         => $this->name,
            'email'        => $this->email,
            'phone'        => $this->phone,
        );

$this_when contains a unix timestamp and I would like to add a new type of time wich is when_rel, it should contain the number of days from today that the unix timestamp refers to. (1, 2 etc.)

I would like t know how to apply math to a value fetched from an array. I tried this but it just puts out an error:

            'when_rel'     => ($this->when/60);

Answer 1

Have you tried 'when_rel' => ($this->when/60)?
