});
A default value may also be passed as the third parameter:

A default value may also be passed as the third parameter:
$value = array_last($array, $callback, $default);
The array_flatten
method will flatten a multi-dimensional array into a single level.

// ['Joe', 'PHP', 'Ruby'];
The array_forget
method will remove a given key / value pair from a deeply nested array using "dot" notation.
$array = ['names' => ['joe' => ['programmer']]];
array_forget($array, 'names.joe');

method will retrieve a given value from a deeply nested array using "dot" notation.
$array = ['names' => ['joe' => ['programmer']]];

Note: Want something like
array_get
but for objects instead? Useobject_get
.
The array_only
method will return only the specified key / value pairs from the array.
$array = ['name' => 'Joe', 'age' => 27, 'votes' => 1];
