We didn't find it - ended up using either;



<?php

$m = new Mongo();



$adminDB = $m->admin; //require admin priviledge



$mongodb_info = $adminDB->command(array('buildinfo'=>true));

$mongodb_version = $mongodb_info['version'];



print_r($mongodb_info);

?>



or



<?php

$v = `mongo --version`;

print_r($v);

?>

I tried to write MapReduce. Unfortunately, out => array('replace' => 'collName') did not work for me. Instead, the below code works





<?php


$mongo->command(array(


     'mapreduce' => 'events',


     'map' => $map,


     'reduce' => $reduce,


     'out' => 'mapReduceEventStats'


));


?>

rename a collection: 





<?php


$m = new Mongo();


$adminDB = $m->admin; //require admin priviledge





//rename collection 'colA' in db 'yourdbA' to collection 'colB' in another db 'yourdbB'





$res = $adminDB->command(array(


    "renameCollection" => "yourdbA.colA",


    "to" => "yourdbB.colB"


));





var_dump($res);


?>
