Question

当我向一个从mongo中删除文档的函数调用2次或更多次时，我遇到了问题。

这是功能：

function deleteUser($userId){
    $rangeQuery = array('metadata.userId' => intval($userId));
    $cursor = $this->collection->remove($rangeQuery);
}

如果我只调用一次，函数可以正常工作。问题是当我多次调用该函数时。例如：

deleteUser(2);
deleteUser(3);
deleteUser(4);

此代码仅删除第一个用户（UserId = 2）。用户3或4未被删除。我需要重新加载页面以删除3，另一个重新加载以删除4.在mongo中删除文档有任何限制吗？

这是使用php mongolog类的日志：

谢谢你！

Answer 1

function deleteUser($userId){
    $rangeQuery = array('metadata.userId' => userId);
    $cursor = $this->collection->remove($rangeQuery);
}

您在userId变量之前缺少$符号。

它应该是：

$rangeQuery = array('metadata.userId' => $userId);

我建议您打开PHP错误日志以捕获此类错误：）

调用2次删除mongo文档的php函数
