Laravel includes a new utility function called
data_forget that allows you to remove keys from an array or object using "dot" notation, and is included since Laravel v10.15.
Let's take a look at how the
data_forget helper works:
$data = ['people' => ['john' => ['address' => '123 main', 'state' => 'nc'],'michael' => ['address' => '34 east 5th', 'state' => 'ny']]];data_forget($data, 'people.*.address');
data_forget function removes the 'address' attribute from both the "john" and "jane" sub-array. The result will then be:
['people' => ['john' => ['state' => 'nc'],'michael' => ['state' => 'ny']]];
One of the neat features of the
data_forget helper is its flexibility. It supports wildcard characters and complete 'dot' notation.
For instance, in the example above, the wildcard character (*) is used in the key string, specifying any sub-key under 'name'. Alternatively, if you need to remove a key from a specific sub-array, you can do so using the complete 'dot' notation, like so:
