在PHP中计数mongodb [英] count mongodb in php

问题描述

我有一个集合用户，该用户具有2个参数(用户名，已付费)，用户名也是一个字符串，而付费也是一个字符串，我应该计算有多少个用户使用了参数paid ="true"

I have a collection user which has 2 parameters (Username,paid), username is a string and paid is a string too, i should count how many users with the parameter paid="true"

这是我的尝试

<?php

$connection = new MongoClient();
$collection = $connection->Ahmed->user;

$cursor = $collection->find();
var_dump($collection->count());
var_dump($collection->count($cursor->paid=>"true")));
?>

如果mongo的专家可以提供帮助，谢谢:)

if there is an expert in mongo could help, thanks :)

推荐答案

新驱动程序未实现$cursor->count()，而使用$collection->count()代替

The new driver does not implement $cursor->count() use $collection->count() instead

$collection->count($filter)

以您的情况为例:$filter = array('paid' => 'true')
