Method	Description
keymap ( Traversable $traversable, Closure $key, Closure $value = null ) : array	Creates an associative array from iterator which doesn't return proper keys.

Method Details

keymap() public static method

Keys are generated by applying callback $key to the current value. It is also possible to apply another callback directly to the value. Key callback is called BEFORE value callback. Example:


$data = \Jyxo\Spl\ArrayUtil::keymap($iterator, function(Object $object) {
  return $object->getId();
});

public static keymap ( Traversable $traversable, Closure $key, Closure $value = null ) : array
$traversable	Traversable	Iterator
$key	Closure	Closure for generating keys
$value	Closure	Closure for modifying data (Optional)
return	array

range() public static method

Params $low and $high are inclusive. If $low > $high, resulting array will be in descending order.

public static range ( mixed $low, mixed $high, Closure $step, Closure $compare = null ) : array
$low	mixed	Minimal value
$high	mixed	Maximal value
$step	Closure	Closure which creates next value from current
$compare	Closure	comparing closure for detecting if we're at the end of the range (Optional)
return	array
