我想知道我是否可以准备一个执行多个查询的mysqli语句：

mysqli->prepare(query1 ...1,2,3 param...; query2...4,5 param...);
or 
mysqli->prepare(insert into ...1,2,3 param...; insert into...4,5 param...);
and after all
mysqli->bind_param("sssss", 1, 2, 3, 4, 5);

这样就会出错：在…中的非对象上调用成员函数bind_param（）

$stmt = $sql->getQueryPrepare("INSERT INTO user (id_user, username, pw, email) VALUES (?,?,?,?); INSERT INTO process (id_user, idp) VALUES (?,?);");

$stmt->bind_param("ssssss",$id, $username, $pw, $email, $id, $idp);

$stmt->execute();
$stmt->close();
