Laravel how to store an array in to database

问题

I store data into array[], when i do dd(($request)); i can see the array with the date.

Question how i can store it inside the DB?

blade

<div class="form-group">
                    <label for="qualifiche">qualifiche:</label>
                    <input type="checkbox" name="array[]" value="uno" > Uno <br>
                    <input type="checkbox" name="array[]" value="due"> Due <br>
                    <input type="checkbox" name="array[]" value="tre"> Tre <br>
                </div>

You have two main options:

Option 1:

first Serialize the array and save it:

$arr = serialize($request['array']);

Then when you retrieve the data you do something like: // $model->attribute will be replaced with ur Model name and attribute $data = unserialize($model->attribute);

Here is the documentation: http://us.php.net/manual/en/function.serialize.php

Option 2:

Construct a string manually from the array and save it as a string: // !! is the delimiter you can use whatever u want... $data = implode('!!', $request['array]);

and you can have the array back using:

$array = explode('!!', $model->attribute);

For Laravel:

You can write a getter to get the data as an array without doing it manually:

public function getSomethingAttribute($value)
{
    // if using serialize
    return unserialize($value);
    // or if using implode
    return explode('!!', $value)

}

Extra:

You can also store it as JSON if the database field is set as JSON or Text...if it's the case parse the array and save it.
