Cast Laravel query results to class

Question

When creating a query using the syntax DB::table(\'foo\'), it creates a generic class (stdClass). Is there any way to cast the resulting rows to a specific class?

Answer 1

Laravel 5.8

In the class you want to cast to (YourClass in this example) to you'll need constructor like this:

    /**
     * Use to initialize fields from DB query like:
     * $query->mapInto(YourClass::class)
     *
     * YourClass constructor.
     * @param \stdClass $data
     */
    public function __construct(\stdClass $data)
    {
        foreach ($data as $key => $value) {
            $this->$key = $value;
        }
    }

Then in your query:

$result = $query
->get()
->mapInto(YourClass::class);

$result will now contain a collection of YourClass instances with fields loaded from the query.
