Installation

The best way to install it is via Composer. Just add nexendrie/utils to your dependencies.

Collection

This package contains abstract class Nexendrie\Utils\Collection which is a base for collection of objects of specified type. The type is stored in property $class. The collection behaves like an array - you can use count() on it, you can iterate over the items in foreach, you can even add new items as next element of array. Example of usage:

class MyCollection extends Nexendrie\Utils\Collection {
  protected $class = Item::class;
}

$collection = new MyCollection();
$collection[] = new Item();
$collection[] = new Item();
count($collection); // 2
foreach($collection as $index => $item) {
  if($index === 1) {
    unset($collection[$index]);
  }
}
count($collection); // 1

You can even create collection in which all items has to have different values for 1 property. Just set (or overwrite) value for property $uniqueProperty.

If you cannot (or do not want to) extends that class, you can also use trait Nexendrie\Utils\TCollection in your class. Do not forget to make the class implement \ArrayAccess, \Countable and \IteratorAggregate interfaces.

Intervals

There is class Intervals in this package which makes working with number intervals in PHP a piece of cake. It first method findInterval returns interval from input string or NULL if no valid interval was found. The second method isInInterval tells you whether an integer (first argument) is in specified interval (second parameter).
