Example #1 MongoDB::listCollections() example
The following example demonstrates running count on each collection in a database.
<?php
$m = new MongoClient();
$db = $m->selectDB("demo");
$list = $db->listCollections();
foreach ($list as $collection) {
echo "amount of documents in $collection: ";
echo $collection->count(), "\n";
}
?>
Il precedente esempio visualizzerà qualcosa simile a:
... amount of documents in demo.pubs: 4 amount of documents in demo.elephpants: 3 amount of documents in demo.cities: 22840 ...
