No, if the property is private, and the getter is called out of call entry(means 
access a private property out of scope), zend vm will return NULL,  but 
zend_read_property will assume as a "public property name", since PHP is a 
flexible language.

When get_property_info successed in the Example class,
if the private property is defined but be unsetted,zend vm return a property info with name
"\0Example\0propertyname",
but if the property is undefined(or defined but not be unsetted),zend vm return a property info with
name "propertyname".
Is that true?

because there is no '\0Example\0p3' in property_info of  Example class entry

If we add following code:

echo $example->p3;  

It still just call __get once. Why it doesn't call it twice? 
( one for "p3" and one for "\0example\0p3" ? )

In another word: what's the different between a property not defined and a unset 
private property?
