MongoDB PHP 驱动程序:对存储的 JS 使用执行 [英] MongoDB PHP Driver: Using Execute for Stored JS

问题描述

我创建了一个 Stored JS 函数，据说它可以更快、更高效地完成一项非常乏味的工作.现在经过长时间的投入工作，我想出了完成这个功能.

I created a Stored JS function which supposedly completes a very tedious job, faster and efficiently. Now after a investing long working hours I came up with completing this functionality.

所以我的函数是假设 myFunc();

So my function is suppose myFunc();

db.system.js.save(
{
 _id : "myFunc" ,
 value : function (param1,param2,param3....){ ... }});

一旦我完成了这个功能，并使用 Mongo Shell 进行测试

Once I was through with completing this function, and testing it with Mongo Shell as

db.eval("myFunc('a','b'...)");

和

db.loadServerScripts();
myFunc('a','b',..);

我很满意它会起作用，现在问题开始了，如何用PHP来实现这一点?

I was satisfied it will work, Now the problem begins, How to achieve this with PHP?

$cmd = 'db.eval("myFunc(\'a\',\'b\'...);");';
$data = $mongo_db->execute($cmd);
var_dump($data);

$data 一无所获..!!

$data comes up with nothing..!!

array(2) { ["retval"]=> NULL ["ok"]=> float(1) } 

请有人告诉我我到底做错了什么..！！

Somebody tell me please what the heck am I doing wrong..!!

推荐答案

我发现的简单解决方法:

The Simple workaround I found:

var out = db.eval("abc(param1,param2..)"); return(JSON.stringify(out));

我知道它根本不是实现这一目标的可取方法，但直到我找到更好的解决方法(因为存储 JS 不是一种可取的方法)它是我唯一的方法.如有任何失败，将发布.

I know its not at all advisable way to achieve this, but till the time I find a better workaround( as Stored JS is not an advisable method ) its the only way I have. Will post in case of any failure.
