It prints nothing because you have error_reporting disabled in php.ini.
If you enable it you'll see what's going on. For example, here's what
happened when I ran your code:
PHP Warning: DOMDocument::loadHTMLFile(): Unexpected end tag : head in
http://images.google.com/images?q=hello, line: 32 in foo.php on line 7
Warning: DOMDocument::loadHTMLFile(): Unexpected end tag : head in
http://images.google.com/images?q=hello, line: 32 in foo.php on line 7
PHP Warning: DOMDocument::loadHTMLFile(): htmlParseStartTag: misplaced
<body> tag in http://images.google.com/images?q=hello, line: 32 in
foo.phpon line 7
