zend_parse_method_parameters 和 zend_parse_parameters 区别

zend_parse_method_parameters 必须第一个格式字符串是 O

this_ptr作为返回值 返回（赋值给obj_ptr) 且必须是 mchessian_service_ce_ptr类型实例 

if (FAILURE == zend_parse_method_parameters(ZEND_NUM_ARGS() TSRMLS_CC, p_this, "O|o", &obj_ptr, mcphessian_service_ce_ptr, &obj2_ptr)) {

zend_error(E_WARNING, "parse parameters error.");

//return;

}
