Hello 每个人都使用MongoDB的这种方法:

$cursor = $collection->find();
foreach($cursor as $doc) {
   // do something....
}

当我使用超过$doc[_id]的代码表示反对,但我需要加以扼杀时,它就会自动消化我的自称财产。

How can I convert it to string automatically. Not like this:

foreach($cursor as $doc) {      
    $doc[ _id ] = (string)$doc[ _id ];
}
最佳回答

通过<代码>json_encode妥善处理mongo 用于a bug in the php。 应自1.0.11起确定。

问题回答

自动转换目标,从MongoDB-driver产生的任何结果中加以扼杀。

function convertMongoIds(array &$array){
    foreach ($array as &$element){
        if (is_array($element)){
            convertMongoIds($element);
        }else if (is_object($element) && get_class($element) == "MongoId"){
            $element = (string) $element;
        }
    }
}
`$result = $collection->findOne([
      _id  => new MongoDBBSONObjectId("5a59b11b3ffd3aec4a23cd2c")
]);


var_dump((string)$result->_id, $result->_id->__toString());`

这两份文件都是第3.6版。
