A small change to the earlier example will result in a more user-friendly output that will be easier on the eye:

<?php
$dbname
= 'members';    // Previously created database
$conn = new MongoClient("localhost");

$list = $conn->selectDB($dbname)->getCollectionNames();

foreach (
$list as $coltion) {
       
$colName = $coltion;
        echo
'<p>Collection name is: <em>';
        echo
$colName;
        echo
'.</em></p>';
    }
?>

This will produce an output similar to the following;

Collection name is: addresses.
