How do I get the rest of the code to execute when the PHP program executes an error?

For example, the following code, the result of printing only shows the public, and then reported a fatal error, then the occupation skip the mistake to let the next program continue to execute it? The desired output format is
Public
Error
Error
Public protected private




Class MyCLass
{
Public $public = ' public ';
Protected $protected = ' protected ';
Private $private = ' private ';

function Printhello ()
{
Echo $this->public;
Echo $this->protected;
Echo $this->private;
}
};

$obj =new MyCLass ();
Echo $obj->public;
Echo $obj->protected;
Echo $obj->private;
$obj->printhello ();

Reply to discussion (solution)

Try catch capture processing under

Is that so? But the second line of error, the code behind will not be executed AH
try {
Echo $obj->protected;
} catch (Emptyiterator $e) {
Print $e->getmessage ();
}

Cannot access protected property MyCLass:: $protected
Unable to access protected resource

This is a fatal error, not to be avoided!
In other words: You don't know the rules.

You can use simple debugging functions to observe the properties of an object
Print_r ($obj);
Or
Var_dump ($obj);

A fatal error is no way to skip, and once it happens, it stops running.

Thanks, everybody.
