Hi.

Any manual about registering multi classes in one PHP extension?
Simple example:(register two classes named myapp and mylib)
 INIT_CLASS_ENTRY(myapp_class, "myapp", myapp_class_functions); 
 myapp_ptr = zend_register_internal_class(&myapp_class TSRMLS_CC);

 INIT_CLASS_ENTRY(mylib_class, "mylib", mylib_class_functions); 
 mylib_ptr = zend_register_internal_class(&mylib_class TSRMLS_CC);

Now I want write the code in php like following:
<?php
...
$myapp = new myapp();
$myapp->mylib->dosomething(); 
...
?>
The member mylib of myapp is registered in C code, also is an object by mylib class. How to do?
I read some code in ext/(like pear) that contaings that function, but I can hardly understand that code.

Any manual or tutorial about that topic?

Thanks.

Add a constructor for myapp class in the C code. It should be named myapp.
The in the constructor - do getThis() and add property using the
add_property_zva() macro. The zval have to a instance of mylib class (use
object_init_ex()).

Hope this helps,

Andrey
