SYNOPSIS

       array range (mixed  $start, mixed  $end, [number  $step = 1])

DESCRIPTION

	Create an array containing a range of elements.

PARAMETERS

	      o $start
		- First value of the sequence.

	      o $end
		- The sequence is ended upon reaching the $end value.

	      o $step
		-  If  a $step value is given, it will be used as the increment between elements in the sequence. $step should be given as a posi-
		tive number. If not specified, $step will default to 1.

RETURN VALUES

	Returns an array of elements from $start to $end, inclusive.

EXAMPLES

       Example #1

	      foreach (range(0, 12) as $number) {
