mongoexport with php

[dab]

Hello Guys,

I am trying to export mongodb collection via Php code but looks like
it doesn't work,
Here is the code i am using.

exec("mongoexport -d test -c foo -o /web/www/cloud1/MongoDump/
foo.json") or die('Export Failed');

But as I run same command on linux cli, it does work.

Any example will be helpful.

Thanks!

Can you run:

$output = array();
$ret = null;

exec("mongoexport -d test -c foo -o /web/www/cloud1/MongoDump/

foo.json", $output, $ret);
var_dump($output, $ret);

and paste the result?

Thanks for your reply, but luckily script worked and data was also
saved in .json file but somehow I was not getting right output.


here the out put of your shared code:

array(0) { } int(0)

but data saved in foo.json file:
{ "_id" : { "$oid" : "4f687deca3bcdf691b668bfe" }, "name" : "sara" }


Thanks for your reply.

Glad it worked out.

Mongoexport wont output to terminal in this case hence you get no response from the terminal command.

Glad it worked out.

Hi Kristina ,

Your code is working and a file foo.json is also being created... but the thing is the file is emply and has no data in it.. in the terminal I get array(0) { } int(0) ..

Is there something I am missing here... thanks a lot in advance

Are you running this script on the same server as the mongod is running on?

Could you try running the command normally on the command line, rather then through PHP to see what is going on?

Also, did you make any changes to the script, or your mongod setup?
