我可以将mongodb查询作为字符串传递给php吗 [英] can i pass mongodb query as a string in php

问题描述

我正计划从php平台文本区域运行mongodb查询，如下图所示，我想在其中编写查询

I am planning to run mongodb query from php platform text area as picture below where I want to write query like

 array('Chat_time' => array('$gt' => $start, '$lte' => $end))

并像

$m = new MongoClient();
$db = $m->Forensic;
$coll= $db->mobile_
$user_code = $coll->find($_POST['txt_area']));

但是不能执行，因为我认为当我将查询转换为字符串时，它不能将=>理解为命令.

but cannot execute becuause I think when I convert query to string it cannot understand => as a command.

什么是传递此命令的最佳方式，因为字符串和php会理解.

what would be the best way pass this command as a string and php will understand.

推荐答案

，您应该将json写入文本区域.像:

you should write json to your text area. like:

{
    "Chat_time": {
        "$gt" => "xxx",
        "$lte" => "yyy"
    }
}

在php

// json string to array using json_decode
$query = json_decode($_POST['txt_area'], true);
$user_code = $coll->find($query);
