Array helper
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 = ['foo' => ['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($array, 'foo.baz', 'hello world');
The set
method allows you to append an array value using "dot notation".
Arr::append($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(['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([1, 2, 3]);
// $assoc will be set to "true"
$assoc = Arr::isAssoc(['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 =
[
['name' => 'apple', 'color' => 'green'],
['name' => 'banana', 'color' => 'yellow'];
];
$colors = Arr::pluck($fruits, 'color');
