将PHP对象插入MONGO DB [英] Inserting a PHP Object Into a MONGO DB

问题描述

我有一个要存储在Mongo数据库中的php对象.在数据库中存储对象的最佳方法是什么?我当时正在考虑遍历对象并创建一个数组，但这是一个复杂的对象，它也具有子对象.谢谢

I have a php object that I would like to store in my Mongo database. What is the best way to store the object in the database? I was thinking of looping over the object and creating an array but this is a complex object that has sub objects as well. Thanks

推荐答案

最简单的方法可能是使对象可广播"到数组.

The easiest way is probably to make your object "castable" to an array.

如果要存储的属性是public，则可以执行以下操作:

If the properties you want to store are public, you can just do:

$array = (array)$foo;

否则，toArray方法或使其实现Iterator接口将起作用:

Otherwise, a toArray method, or making it implement an Iterator interface will work:

class Foo implements IteratorAggregate {

   protected $bar = 'hello';

   protected $baz = 'world';

   public function getIterator() {
       return new ArrayIterator(array(
           'bar' => $this->bar,
           'baz' => $this->baz,
       ));
   }

}

很明显，您也可以使用get_object_vars，Reflection等代替在getIterator方法中对属性列表进行硬编码.

Obviously, you can also use get_object_vars, Reflection and such instead of hardcoding the property list in the getIterator method.

然后，只是:

$foo = new Foo;
$array = iterator_to_array($foo);
$mongodb->selectCollection('Foo')->insert($array);

根据要存储对象的方式，您可能希望使用DBRef而不是一次存储所有嵌套对象，因此以后可以轻松地分别find将它们分开.如果不是，则使您的toArray方法递归.

Depending on how you want to store your objects, you may want to use DBRefs instead of storing nested objects all at once, so you can easily find them separately afterwards. If not, just make your toArray method recursive.
