Question

For example, I have User model extending Eloquent. In the database table, the column name is user_id.

How do I output the result as \'userId\' after re

Answer 1

I do it in this way.

protected $remap_attrs = ['old_name' => 'new_name'];
public function toArray(){
    $array = parent::toArray();
    foreach($this->remap_attrs as $key => $new_key) {
        if(array_key_exists($key, $array)) {
            $array[$new_key] = $array[$key];
            unset($array[$key]);
        }
    }
    return $array;
}
