Re: Using an existing extension in a custom extension

Hello all, here's what I'm trying to do: I'm writing a PHP extension in C and I'd like to create a DOMDocument object in my C code that I could send back to my PHP code. I have been trying many things, like: #include "ext/dom/php_dom.h" .... zval *doc; MAKE_STD_ZVAL(doc); object_init_ex(doc, dom_document_class_entry); zval c_ret, constructor; INIT_ZVAL(c_ret); INIT_ZVAL(constructor); ZVAL_STRING(&constructor, ZEND_CONSTRUCTOR_FUNC_NAME, 1); call_user_function(NULL, &doc, &constructor, &c_ret, 0, NULL TSRMLS_CC); It compiles, but when I call my function, it fails on object_init_ex (and when I say it fails, it stops apache...). I've also tried things like: zend_call_method(NULL, dom_document_class_entry, dom_document_class_entry->constructor, ZEND_CONSTRUCTOR_FUNC_NAME, strlen(ZEND_CONSTRUCTOR_FUNC_NAME), &doc, 2, "1.0", "UTF-8" TSRMLS_CC); but it stills kill apache each time. Does anyone know how to do this? Is this even feasible? Include dom/xml_common.h and use the DOM_RET_OBJ macro.

That will make sure everything is created properly. You should be able to find an example of this in the xsl extension. Rob
