Example #1 MongoDB::listCollections example

The following example demonstrates dropping each collection in a database.

<?php

$m = new MongoClient();
$db = $m->selectDB("sample");

$list = $db->listCollections();
foreach ($list as $collection) {
    echo "removing $collection... ";
    $collection->drop();
    echo "gone\n";
}

?>

The above example will output something similar to:

removing sample.blog.posts... gone
removing sample.critical.docs... gone
removing sample.taxes... gone
...
