mongodb num_rows等效的php [英] mongodb num_rows equivalent php

问题描述

我如何获得等于mongodb中的num_rows(mysqli)的结果数?

how can i get the number of results, equivalent to num_rows(mysqli) in mongodb?

如果我有

$db->$dbName->find(array("email" => $newemail, "password" => $newpass));

检查符合此条件的结果数量的最佳方法是什么?

在mysqli中，我会做类似的事情

what is the best way to check the number of results that match this criteria?

in mysqli i would do something like

$sql = "SELECT id FROM table WHERE email='%s' AND password='%s'";
$query = sprintf($sql, $newemail, $newpass);
$result = $conn->query($query);
$rows = $result->num_rows;

推荐答案

就像这样，我认为:

$collection = $connection->myDB->myCollection;
$cursor = $collection->find(array("email" => $newemail, "password" => $newpass));
$nResults = $cursor->count();
