{
set_error_handler(array(__CLASS__, 'errorHandler'));
}
public static function errorHandler($errno, $errstr, $errfile, $errline)
{
throw new ErrorException($errstr, 0, $errno, $errfile,
$errline);
}
}
class cache implements ArrayAccess
{
private $container = array();
public function offsetGet($id) {}
public function offsetSet($id, $value) {}
public function offsetUnset($id) {}
public function offsetExists($id)
{
return isset($this->containers[(string) $id]);
}
}
$env = new env();

var_dump(isset($cache[$id]));
