$config = array('accessibility-check' => 3,
'alt-text' => 'some text');
$tidy = new tidy();
$tidy->parseString($html, $config);
var_dump($tidy->getOpt('accessibility-check')); //integer
var_dump($tidy->getOpt('lower-literals')); //boolean
var_dump($tidy->getOpt('alt-text')); //string
?>
The above example will output:
int(3)
bool(true)
string(9) "some text"
