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 = ['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.
$array = ['foo' => 'bar'];
list($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 = ['foo' => ['bar' => 'baz']];
$array = array_dot($array);
// ['foo.bar' => 'baz'];
array_except
The array_except method removes the given key / value pairs from the array.
$array = array_except($array, ['keys', 'to', 'remove']);
array_fetch
The array_fetch method returns a flattened array containing the selected nested element.
$array = [
['developer' => ['name' => 'Taylor']],
['developer' => ['name' => 'Dayle']]
];
$array = array_fetch($array, 'developer.name');
// ['Taylor', 'Dayle'];
array_first
The array_first method returns the first element of an array passing a given truth test.
$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 = [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 = ['name' => 'Joe', 'languages' => ['PHP', 'Ruby']];
$array = array_flatten($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.
$array = ['names' => ['joe' => ['programmer']]];
array_forget($array, 'names.joe');
array_get
The array_get method will retrieve a given value from a deeply nested array using "dot" notation.
$array = ['names' => ['joe' => ['programmer']]];
$value = array_get($array, 'names.joe');
$value = array_get($array, 'names.john', 'default');
Note: Want something like
array_getbut for objects instead? Useobject_get.
array_only
The array_only method will return only the specified key / value pairs from the array.
$array = ['name' => 'Joe', 'age' => 27, 'votes' => 1];
$array = array_only($array, ['name', 'votes']);
array_pluck
The array_pluck method will pluck a list of the given key / value pairs from the array.
$array = [['name' => 'Taylor'], ['name' => 'Dayle']];
$array = array_pluck($array, 'name');
// ['Taylor', 'Dayle'];
array_pull
The array_pull method will return a given key / value pair from the array, as well as remove it.
$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.
$array = ['names' => ['programmer' => 'Joe']];
array_set($array, 'names.editor', 'Taylor');
array_sort
The array_sort method sorts the array by the results of the given Closure.
$array = [
['name' => 'Jill'],
['name' => 'Barry']
];
$array = array_values(array_sort($array, function($value)
{
return $value['name'];
}));
array_where
Filter the array using the given Closure.
$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.
$first = head($this->returnsArray('foo'));
last
Return the last element in the array. Useful for method chaining.
$last = last($this->returnsArray('foo'));
