October includes a variety of "helper" PHP functions. Many of these functions are used internally by October itself, however, you are free to use them in your own plugins and applications if you find them useful.
<style> .collection-method-list > p { column-count: 3; -moz-column-count: 3; -webkit-column-count: 3; column-gap: 2em; -moz-column-gap: 2em; -webkit-column-gap: 2em; } .collection-method-list a { display: block; } </style>The array_add function adds a given key / value pair to the array if the given key doesn't already exist in the array:
$array = array_add(['name' => 'Desk'], 'price', 100);
// ['name' => 'Desk', 'price' => 100]
The array_divide function returns two arrays, one containing the keys, and the other containing the values of the original array:
list($keys, $values) = array_divide(['name' => 'Desk']);
// $keys: ['name']
// $values: ['Desk']
The array_dot function flattens a multi-dimensional array into a single level array that uses "dot" notation to indicate depth:
$array = array_dot(['foo' => ['bar' => 'baz']]);
// ['foo.bar' => 'baz'];
The array_undot function is the counter-part to the array_dot method. It will convert a dot-notated array into a standard associative array:
$array = array_undot([
'foo.bar' => 'baz'
]);
// [
// 'foo' => [
// 'bar' => 'baz'
// ]
// ]
The array_except method removes the given key / value pairs from the array:
$array = ['name' => 'Desk', 'price' => 100];
$array = array_except($array, ['price']);
// ['name' => 'Desk']
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;
});
// 200
A default value may also be passed as the third parameter to the method. This value will be returned if no value passes the truth test:
$value = array_first($array, $callback, $default);
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'];
The array_forget method removes a given key / value pair from a deeply nested array using "dot" notation:
$array = ['products' => ['desk' => ['price' => 100]]];
array_forget($array, 'products.desk');
// ['products' => []]
The array_get method retrieves a value from a deeply nested array using "dot" notation:
$array = ['products' => ['desk' => ['price' => 100]]];
$value = array_get($array, 'products.desk');
// ['price' => 100]
The array_get function also accepts a default value, which will be returned if the specific key is not found:
$value = array_get($array, 'names.john', 'default');
The array_only method will return only the specified key / value pairs from the given array:
$array = ['name' => 'Desk', 'price' => 100, 'orders' => 10];
$array = array_only($array, ['name', 'price']);
// ['name' => 'Desk', 'price' => 100]
The array_pluck method will pluck a list of the given key / value pairs from the array:
$array = [
['developer' => ['name' => 'Brian']],
['developer' => ['name' => 'Stewie']]
];
$array = array_pluck($array, 'developer.name');
// ['Brian', 'Stewie'];
The array_pull method returns and removes a key / value pair from the array:
$array = ['name' => 'Desk', 'price' => 100];
$name = array_pull($array, 'name');
// $name: Desk
// $array: ['price' => 100]
The array_set method sets a value within a deeply nested array using "dot" notation:
$array = ['products' => ['desk' => ['price' => 100]]];
array_set($array, 'products.desk.price', 200);
// ['products' => ['desk' => ['price' => 200]]]
The array_sort method sorts the array by the results of the given Closure:
$array = [
['name' => 'Desk'],
['name' => 'Chair'],
];
$array = array_values(array_sort($array, function ($value) {
return $value['name'];
}));
/*
[
['name' => 'Chair'],
['name' => 'Desk'],
]
*/
The array_sort_recursive function recursively sorts the array using the sort function:
$array = [
[
'Brian',
'Shannon',
'Alec',
],
[
'PHP',
'Ruby',
'JavaScript',
],
];
$array = array_sort_recursive($array);
/*
[
[
'Alec',
'Brian',
'Shannon',
],
[
'JavaScript',
'PHP',
'Ruby',
]
];
*/
The array_where function filters the array using the given Closure:
$array = [100, '200', 300, '400', 500];
$array = array_where($array, function ($value, $key) {
return is_string($value);
});
// [1 => 200, 3 => 400]
The head function simply returns the first element in the given array:
$array = [100, 200, 300];
$first = head($array);
// 100
The last function returns the last element in the given array:
$array = [100, 200, 300];
$last = last($array);
// 300
