<?php

namespace OpenCFP\Entity\Mapper;

use Spot\Mapper;

class User extends Mapper
{
    /**
     * Return an array that grabs info from the User and Speaker entities
     *
     * @param integer $user_id
     * @return array
     */
    public function getDetails($user_id)
    {
        $user = $this->all()
            ->where(['id' => $user_id])
            ->with(['speaker'])
            ->limit(1);

        return [
            'photo_path' => $user[0]->photo_path,
            'first_name' => $user[0]->first_name,
            'last_name' => $user[0]->last_name,
            'airport' => $user[0]->airport,
            'email' => $user[0]->email,
            'twitter' => $user[0]->twitter,
            'bio' => $user[0]->speaker->bio,
            'info' => $user[0]->speaker->info,
            'transportation' => $user[0]->transportation,
            'hotel' => $user[0]->hotel
        ];
    }
}

This could probably be better done like this:

<?php

namespace OpenCFP\Entity\Mapper;

use Spot\Mapper;

class User extends Mapper
{
    /**
     * Return an array that grabs info from the User and Speaker entities
     *
     * @param integer $user_id
     * @return array
     */
    public function getDetails($user_id)
    {
        $user = $this->where(['id' => $user_id])
            ->with(['speaker'])
            ->first(); // Will automatically apply the `limit(1)`

        return $user->toArray();
    }
}

If you have access to the statement obj, just do a return $stmt-->fetch()
