Seeing this, I already wondered before: Why is the struct tag even prefixed with an underscore instead of matching the typedef'd name exactly?

I think this is just an convention to avoid having identical names. And maybe also as a hint that clients should use the typedef'd name.

struct _zend_class_entry;
struct _zend_object;
struct _zend_object_iterator;
struct _zval_struct;

typedef enum {
ZEND_PROPERTY_HOOK_GET = 0,
ZEND_PROPERTY_HOOK_SET = 1,
} zend_property_hook_kind;

ZEND_API zend_object_iterator *zend_hooked_object_get_iterator(zend_class_entry *ce, zval *object, int by_ref);
ZEND_API zend_array *zend_hooked_object_build_properties(zend_object *zobj);
ZEND_API struct _zend_object_iterator *zend_hooked_object_get_iterator(
struct _zend_class_entry *ce, struct _zval_struct *object, int by_ref);
ZEND_API struct _zend_array *zend_hooked_object_build_properties(struct _zend_object *zobj);
