Hi,
It's a nice class, but I found a small issue.
in line 82, there's this line:
$this->stack[$this->pointer]++;

since $this->stack[$this->pointer] is not defined at first, so a notice is displayed by PHP.
By adding the followin lines before the switch block, the problem will be solved:

if (!isset($this->stack[$this->pointer])) {
$this->stack[$this->pointer]=0;
}

:)
