data_get(): Warning with array keys with dots - Laravel Tips

#laravel #tips #webdev #learning

Ingredients

`data_get()`

data_get() is a useful helper function in Laravel that retrieves values from a nested array or an object using dot notation.
The strength of data_get() is also that it accepts wildcards.

If you don't know or you don't use it, I suggest you to discover it (here the docs), with brothers and sisters: data_set(), data_fill(), data_forget()! ;)

`Arr::get()`

Unlike data_get(), Arr::get() works only on arrays and it doesn't accept wildcards.

The Tip

Let’s show this example:



$array = [
    'key.sub' => 'a-value'
];

data_get($array, 'key.sub');  // --> null ❗

// instead...
\Arr::get($array, 'key.sub'); // --> "a-value"

Instead of this:



$array = [
    'key' => [
        'sub' => 'a-value'
    ]
];

data_get($array, 'key.sub');  // --> "a-value"

// and also...
\Arr::get($array, 'key.sub'); // --> "a-value"
