Subject: Re: [PHP-DEV] Internal zvals can't be arrays
From: sklar@sklar.com (David Sklar)

I think your humor is too subtle for me. I don't understand what you 
mean. If I do this:

PHP_METHOD(test_class,__construct);
zend_class_entry *test_class_ce_ptr = NULL;

static zend_function_entry test_class_functions[] = {
     PHP_ME(test_class, __construct, NULL, ZEND_ACC_PUBLIC)
     {NULL, NULL, NULL}
};

And then I put this in my MINIT function:

INIT_CLASS_ENTRY(ce, "test_class", test_class_functions);
test_class_ce_ptr = zend_register_internal_class(&ce TSRMLS_CC);
zend_declare_property_null(test_class_ce_ptr, "test_property",
     sizeof("test_property")-1, ZEND_ACC_PUBLIC TSRMLS_CC);

And I make test_class's constructor look like this:

PHP_METHOD(test_class, __construct) {
     zval *tmp = NULL;
     ALLOC_ZVAL(tmp);
     tmp->is_ref = 0;
     tmp->refcount = 0;
     array_init(tmp);
     add_next_index_long(tmp, 100);
     zend_update_property(test_class_ce_ptr, this_ptr, "test_property", 
sizeof("test_property")-1, tmp TSRMLS_CC);
}

Then this PHP program:

$e = new test_class();
print new ReflectionClass($e);
var_dump($e);

Prints:

Class [ <internal> class test_class ] {

   - Constants [0] {
   }

   - Static properties [0] {
   }

   - Static methods [0] {
   }

   - Properties [1] {
     Property [ <default> public $test_property ]
   }

   - Methods [1] {
     Method [ <internal> <ctor> public method __construct ] {
     }
   }
}
object(test_class)#1 (1) {
   ["test_property"]=>
   array(1) {
     [0]=>
     int(100)
   }
}

So it would be handy (since all the property creation would be in one 
place and there wouldn't be the confusing inference from reading the 
code that the property is NULL) if I could create the array zval in 
MINIT instead of in the constructor.
