• Usage

---

The array helper contains methods that can be useful when working with arrays.

---

Usage

The get method returns a value from an array using "dot notation".

$array = array('foo' => array('bar' => 'baz'));

$bar = Arr::get($array, 'foo.bar');

// You can also specify a default value if the key doesn't exist

$baz = Arr::get($array, 'foo.baz', 'nope');

The set method sets an array value using "dot notation".

Arr::set($array, 'foo.baz', 'hello world');

The delete method deletes an array value using "dot notation".

Arr::delete($array, 'foo.bar');

The random method returns a random array value.

Arr::random(array('green', 'blue', 'red', 'orange'));

The isAssoc method returns TRUE if the array is associative and FALSE if not.

// $assoc will be set to FALSE

$assoc = Arr::isAssoc(array(1, 2, 3));

// $assoc will be set to TRUE

$assoc = Arr::isAssoc(array('one' => 1, 'two' => 2, 'three' => 3))

The pluck method returns the values from a single column of the input array, identified by the key.

$fruits = array
(
	array('name' => 'apple', 'color' => 'green'),
	array('name' => 'banana', 'color' => 'yellow');
);

$colors = Arr::pluck($fruits, 'color');
