Re: hook cast_object handler in userspace

I made a patch to the latest PHP5-CVS wich implements this hook. I think it's useful to make a meaningful object stringfied value. Can anyone verify it and maybe commit it to CVS ? --- zend.c 2003-07-30 14:07:36.000000000 -0300 +++ zend.c.new 2003-08-03 00:27:43.000000000 -0300 @@ -227,10 +227,24 @@ if (expr->value.obj.handlers->cast_object) { TSRMLS_FETCH(); expr->value.obj.handlers->cast_object(expr, expr_copy, IS_STRING, 0 TSRMLS_CC); } else { - expr_copy->value.str.val = (char *) emalloc(sizeof("Object id #")-1 + MAX_LENGTH_OF_LONG); - expr_copy->value.str.len = sprintf(expr_copy->value.str.val, "Object id #%ld", (long)expr->value.obj.handle); + //call to_string method + zval *fname, *retval; + MAKE_STD_ZVAL(fname); + ZVAL_STRING(fname, "to_string", 1); + TSRMLS_FETCH(); + if (call_user_function_ex(NULL, &expr, fname, &retval, 0, NULL, 0, NULL TSRMLS_CC) == SUCCESS) { + if (Z_TYPE_P(retval) != IS_STRING) { + convert_to_string(retval); + } + ZVAL_STRINGL(expr_copy, Z_STRVAL_P(retval), Z_STRLEN_P(retval), 1); + zval_ptr_dtor(&retval); + } else { + Z_STRVAL_P(expr_copy) = (char *) emalloc(sizeof("Object id #")-1 + MAX_LENGTH_OF_LONG); + Z_STRLEN_P(expr_copy) = sprintf(Z_STRVAL_P(expr_copy), "Object id #%ld", (long)Z_OBJ_HANDLE_P(expr)); + } + zval_ptr_dtor(&fname); } #if 0 /* FIXME: This might break BC for some people */ expr_copy->value.str.len = sizeof("Object")-1; Thanx, Cristiano Duarte.
