Arrays

array_add

The array_add function adds a given key / value pair to the array if the given key doesn't already exist in the array.

$array = array['foo' => 'bar']; $array = array_add[$array, 'key', 'value'];

array_divide

The array_divide function returns two arrays, one containing the keys, and the other containing the values of the original array.

$array = array['foo' => 'bar']; list[$keys, $values] = array_divide[$array];

array_dot

The array_dot function flattens a multi-dimensional array into a single level array that uses "dot" notation to indicate depth.

$array = array['foo' => array['bar' => 'baz']]; $array = array_dot[$array]; // array['foo.bar' => 'baz'];

array_except

The array_except method removes the given key / value pairs from the array.

$array = array_except[$array, array['keys', 'to', 'remove']];

array_fetch

The array_fetch method returns a flattened array containing the selected nested element.

$array = array[ array['developer' => array['name' => 'Taylor']], array['developer' => array['name' => 'Dayle']], ]; $array = array_fetch[$array, 'developer.name']; // array['Taylor', 'Dayle'];

array_first

The array_first method returns the first element of an array passing a given truth test.

$array = array[100, 200, 300]; $value = array_first[$array, function[$key, $value] { return $value >= 150; }];

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

$value = array_first[$array, $callback, $default];

array_last

The array_last method returns the last element of an array passing a given truth test.

$array = array[350, 400, 500, 300, 200, 100]; $value = array_last[$array, function[$key, $value] { return $value > 350; }]; // 500

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

$value = array_last[$array, $callback, $default];

array_flatten

The array_flatten method will flatten a multi-dimensional array into a single level.

$array = array['name' => 'Joe', 'languages' => array['PHP', 'Ruby']]; $array = array_flatten[$array]; // array['Joe', 'PHP', 'Ruby'];

array_forget

The array_forget method will remove a given key / value pair from a deeply nested array using "dot" notation.

$array = array['names' => array['joe' => array['programmer']]]; array_forget[$array, 'names.joe'];

array_get

The array_get method will retrieve a given value from a deeply nested array using "dot" notation.

$array = array['names' => array['joe' => array['programmer']]]; $value = array_get[$array, 'names.joe']; $value = array_get[$array, 'names.john', 'default'];

Note: Want something like array_get but for objects instead? Use object_get.

array_only

The array_only method will return only the specified key / value pairs from the array.

$array = array['name' => 'Joe', 'age' => 27, 'votes' => 1]; $array = array_only[$array, array['name', 'votes']];

array_pluck

The array_pluck method will pluck a list of the given key / value pairs from the array.

$array = array[array['name' => 'Taylor'], array['name' => 'Dayle']]; $array = array_pluck[$array, 'name']; // array['Taylor', 'Dayle'];

array_pull

The array_pull method will return a given key / value pair from the array, as well as remove it.

$array = array['name' => 'Taylor', 'age' => 27]; $name = array_pull[$array, 'name'];

array_set

The array_set method will set a value within a deeply nested array using "dot" notation.

$array = array['names' => array['programmer' => 'Joe']]; array_set[$array, 'names.editor', 'Taylor'];

array_sort

The array_sort method sorts the array by the results of the given Closure.

$array = array[ array['name' => 'Jill'], array['name' => 'Barry'], ]; $array = array_values[array_sort[$array, function[$value] { return $value['name']; }]];

array_where

Filter the array using the given Closure.

$array = array[100, '200', 300, '400', 500]; $array = array_where[$array, function[$key, $value] { return is_string[$value]; }]; // Array [ [1] => 200 [3] => 400 ]

head

Return the first element in the array. Useful for method chaining in PHP 5.3.x.

$first = head[$this->returnsArray['foo']];

last

Return the last element in the array. Useful for method chaining.

$last = last[$this->returnsArray['foo']];
