You're trying to echo a Hide() object, which PHP doesn't know how to convert to a string. This is due to the following lines:

        if( $this->name == null ){
           $this->name = new Hide();
      }
      return $this->name;

and then

echo $run->name();

Instead of echo, try

print_r($run->name());

It's worth noting that you can hook into the magic function `__toString` which PHP tries to call when you echo an object. – Kevin Jun 04 '11 at 17:02

You return an instance of Hide and try to echo it. Since your implementation does not have a __toString() method, there is no string representation and you get that error. Try this:

$run = new damu();
echo $run->name()->getmyname();

or add a __toString() method to Hide.

You should be returning

return $this->name->getmyname();

or define a tostring for the Hide class

public function __toString() {
     return "str";   }

You are returning an instance of the class Hide

if( $this->name == null ){
  $this->name = new Hide();
}
return $this->name;

and then you try to echo that instance here:

echo $run->name();

echo, expects a string. That's why you get the error.

As Christopher Armstrong said, you're trying to use a Hide() object as a string, and PHP doesn't know how to convert it. You could, however, try to convert it to a string using this code:

$myText = (string)$myVar;

Wich I found here: ToString() equivalent in PHP

I also found something here that may help you.
