```php
stack = array();
// stack can only contain this many items
$this->limit = $limit;
}
public function push($item) {
// trap for stack overflow
if (count($this->stack) < $this->limit) {
// prepend item to the start of the array
array_unshift($this->stack, $item);
} else {
throw new RunTimeException('Stack is full!');
}
}
public function pop() {
if ($this->isEmpty()) {
// trap for stack underflow
throw new RunTimeException('Stack is empty!');
} else {
// pop item from the start of the array
return array_shift($this->stack);
}
}
public function top() {
return current($this->stack);
}
public function isEmpty() {
return empty($this->stack);
}
}
