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?

kind of right, you can refer to zend_std_read_property(in
Zend/zend_object_handlers.c) for more details.
and btw, you seems to be a chinese(using qq email), so if you are interesting
of
php internal, plz look at laruence.com, I will write these down in chinese in
couple of days

p1:
You mean __unset() made the p1 out of $example->properties?
When get_property_info successed,
zend vm return a property info with name "\0Example\0p1"
but it can't find p1 in $example->properties ?
So zend vm try to fetch "\0Example\0p1" and set a getter_guard for
"\0Example\0p1" and call getter again.
p2:
When get_property_info successed,
zend vm return a property info with name "\0Example\0p2"
and p2 can be found in $example->properties.
So zend vm wont try to fetch "\0Example\0p1" but successed and return p2?
