If an array is used as a default parameter value, e.g:

function foo ($arrParam = array ("a", "b", "c")
{
  .
  .
  .
}

If the function is called without the corresponding parameter, i.e. the default parameter value is used, the parameter ($arrParam) will need to be reset first.

<?php

function foo ($arrParam = array ("a", "b", "c"))
{
	var_dump(current($arrParam));
}

foo();
?>

bool(false)

The internal hash pos is set after the last element.
