dot
Description:
Converts a multidimensional array to a single depth "dot" notation array, optionally prepending a string to each array key.
The key values will never be an array, even if empty. Empty arrays will be dropped.
Parameters:
$array(array): Original array$prepend = ''(string): String to prepend
Returns:
- (array)
Example:
use Bayfront\ArrayHelpers\Arr;
$array = [
'name' => [
'first_name' => 'John',
'last_name' => 'Doe'
],
'hobbies' => [ // This empty array will be dropped
]
];
$dot = Arr::dot($array);
undot

Converts array in "dot" notation to a standard multidimensional array.
Parameters:
$array(array): Array in "dot" notation

- (array)
Example:
use Bayfront\ArrayHelpers\Arr;
$array = [
'name.first_name' => 'John',
'name.last_name' => 'Doe'
];
$undot = Arr::undot($array);
set
Description:
Set an array item to a given value using "dot" notation.
Parameters:
$array(array): Original array$key(string): Key to set in "dot" notation$value(mixed): Value of key

Returns:
- (mixed)
Example:
use Bayfront\ArrayHelpers\Arr;
