将对象附加到php中的另一个对象
我有这个对象：
foreach(range(1,$oc->num_users) as $num) {
$user = 'user' . $num;
$$user = mysql_fetch_object(mysql_query("SELECT user".$num.", user".$num."_ready, FROM oc_db WHERE leader='".$_SESSION['username']."' "));
这给出了名为 user1..X 的对象
，稍后我有一个类似的函数，其中我使用代表连接到数据库的用户名的 $$user->$user以获得更多信息。
$$user = mysql_fetch_object(mysql_query("SELECT x, y, z FROM user_db WHERE username='".$$user->$user."' "));
这也会生成名为 user1..X 的对象，但我不想替换之前创建的对象，而是想将此值附加到我在第一个函数中创建的对象中。 $$user 是对象的名称。我想在最后一个函数中做类似 $$user .= fetch_object 的事情，但当然事情没那么简单。
I have this object:
foreach(range(1,$oc->num_users) as $num) {
$user = 'user' . $num;
$user = mysql_fetch_object(mysql_query("SELECT user".$num.", user".$num."_ready, FROM oc_db WHERE leader='".$_SESSION['username']."' "));
This gives objects named user1..X
later I have a simular function like this, where I use the $$user->$user that represent a username to connect to the db to get additional information.
$user = mysql_fetch_object(mysql_query("SELECT x, y, z FROM user_db WHERE username='".$user->$user."' "));
This also makes objects named user1..X, but instead of replacing the object created earlier I want to append this values to the object I created in the first function. $$user is the name of the objects. I would like to do something like $$user .= fetch_object in the last function, but off course it's not that simple.

为了将一个对象附加到另一个对象，您只需迭代第一个对象，然后将找到的每个属性分配给第二个对象：
In order to append one object to another you simply need to iterate through the first object and then assign each property you find to the second one:
顺便说一句，如果您尝试访问对象的
user属性，那么您应该使用$$user->user，如$ $user->$user将尝试访问编号属性（例如，对于对象$user12，您正在尝试访问$user12->user12代码>）。我还会考虑使用数组，正如 fredley 建议的那样（即使用$user[$num]而不是$user = 'user'.$num）。要解决您最初的问题，您可以尝试向
user类添加一个方法，例如append.=连接赋值运算符>，然后使用它将获取的对象附加到当前对象，例如$user->append( fetch_object(...));。在append方法中，您可以定义自己的规则，了解如何将获取的对象添加到当前用户对象。As a couple of asides, if you are trying to access the
userproperty of the object, then you should use$$user->user, as$$user->$userwill be trying to access a numbered property (e.g. for object$user12, you're trying to access$user12->user12). I would also consider using an array, as fredley suggested (i.e. use$user[$num]instead of$user = 'user'.$num).To approach your original question, instead of using the
.=concatenation assignment operator, you could try adding a method to youruserclass, such asappend, then using it to append the fetched object to your current object like$user->append( fetch_object(...));. In theappendmethod, you can define your own rules for how a fetched object is added to your current user object.
