Simpler, Better, Faster, Stronger --------------------------------- [](#simpler-better-faster-stronger) Using *array\_*\* functions against *foreach* is not an easy pick. As this library is made to manage low level actions. We wanted it to be fast, then we compared and we implemented the best choices. (have a look: [PHP7.2](https://i.imgur.com/JUUo6EE.png)) Fully unit tested it is reliable. Methods ------- [](#methods) ### Advanced Selection by range [](#advanced-selection-by-range) ``` $collection = NovaCollection([0,1,2,3,4,5,6,7,8,9,10]); $collection([2,4], 1, 2, '4-2', '3,2;5-2;10')->toArray(); ``` > Result: \[2,3,4,1,2,4,3,2,3,4,5,4,3,2,10\] ### Standard Manipulation Methods [](#standard-manipulation-methods) MethodDescriptiontoArray()Get the raw Array.set($key, $value)Set the value to the key no matter what.get($key, $default)Get the value related to the key.atIndex(int $index)Get the item at the given index (numerically).keyOf($value)Get the key of a value if exists.indexOf($value)Get the index of a value if exists (numerically).containsKey($key)Test is the key exists.contains($value)Test if this values exists.add($item)Add a new value to the collection, next numeric index will be used.
