Using a file clearTestData.php to remove data from a collection in my database. It includes a query that seems to be showing the collection is empty at the end. When I check with list.php however which has the same query, nothing is deleted. Complete mongo noob here, server provided by unviersity. Testing both by accessing through browser "server..../clearTestData.php".
ClearTestData.php:
<?php
// connect to mongodb
$user = "muntean";
require '/var/composer/vendor/autoload.php';
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
echo "Connection to database successfully. ";
$collection = new MongoDB\Collection($manager, $user, 'testData');
echo "deleting contents of collection user.testData. ";
// now remove the document
$collection->remove(array("node"=>"xyzWXX"),false);
// db.testData.deleteMany({});
echo "Documents deleted successfully.";
$filter = [];
$options = [];
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery("$user.testData", $query);
print("The contents of the collection $user.testData are: ");
print_r($cursor->toArray());
?>
list.php:
<html><body>
<?php
$user = "muntean";
require '/var/composer/vendor/autoload.php';
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$collection = new MongoDB\Collection($manager, $user, 'testData');
$filter = [];
$options = [];
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery("$user.testData", $query);
print("The contents of the collection $user.testData are:");
print_r($cursor->toArray());
?>
Output list in browser:
