Ruby's Cycle function in PHP

cycle.php

function cycle($first_value, $values = '*') {
  static $count = array();
  $values = func_get_args();
  $name = 'default';
  $last_item = end($values);
  if( substr($last_item, 0, 1) === ':' ) {
    $name = substr($last_item, 1);
    array_pop($values);
  }
  if( !isset($count[$name]) )
    $count[$name] = 0;
  $index = $count[$name] % count($values);
  $count[$name]++;
  return $values[$index];  
}

/*
 Sample usage:
 for($x=0; $x<=5; $x++){
   echo cycle('one, ','two, ','three, ');
 }
 Output:
 one, two, three, one, two
 
 I mostly use this for ping-ponging markup classes instead of using JS for them.
