typo in line 517

```
in phpQuery.php line 517 you have

if (strpos($hltml, '<html') === false) {

I get:
Notice: Undefined variable: hltml in /path/phpQuery.php on line 517

I think this is a typo, should be

if (strpos($html, '<html') === false) {


making this change got my script to work properly 
```
