I'm writing a PHP class with a method that has to be passed a
DOMDocument object, and it needs to retain that object throughout the
life of its instantiation. However, the (dom_object *) returned from
zend_parse_method_parameters is just a pointer to the passed object,
and so it disappears when the original document is unset or goes out of
scope. How would one go about cloning the DOMDocument to save in the
class's struct?
example:
ZEND_METHOD(xydelta, setStartDocument) {
zval *id, *doc = NULL;
xydelta_object *intern;
if (zend_parse_method_parameters(ZEND_NUM_ARGS() TSRMLS_CC, getThis(),
"Oo", &id, xydelta_ce, &doc) == FAILURE) {
RETURN_FALSE;
}
intern = (xydelta_object *)zend_object_store_get_object(id TSRMLS_CC);
if (intern != NULL) {
// Error checking removed for brevity...
// ...
// This pointer cannot be accessed once the object that was used as
the first parameter goes out of scope
intern->libxml_start_doc = (php_libxml_node_object *)
zend_object_store_get_object(doc TSRMLS_CC);
}
}
