Displaying database content - php

Question

I'm trying to display the database 'hospitaldb', collection 'doctor' content using php. I've fields email, password, fname, lname in the collection. When I try to display these fields then I get error messages as :
Notice: Undefined index: email in C:\xampp\htdocs\phpmongodb\viewdoctor.php on line 40
Notice: Undefined index: password in C:\xampp\htdocs\phpmongodb\viewdoctor.php on line 41
Notice: Undefined index: fname in C:\xampp\htdocs\phpmongodb\viewdoctor.php on line 42
Notice: Undefined index: lname in C:\xampp\htdocs\phpmongodb\viewdoctor.php on line 43
$server = "mongodb://localhost:27017/hospitaldb";
try{
$connection = new MongoDB\Client($server);
/*$hospitaldb = $connection->test;*/
$hospitaldb = $connection->hospitaldb;
}catch (MongoConnectionException $ConErrMsg)
{
echo "$ConErrMsg";
}
$data = "<table style='border:1px solid red;";
$data .= "border-collapse:collapse' border='1px'>";
$data .= "<thead>";
$data .= "<tr>";
$data .= "<th>First Name</th>";
$data .= "<th>Last Name</th>";
$data .= "<th>Email</th>";
$data .= "<th>Password</th>";
$data .= "</tr>";
$data .= "</thead>";
$data .= "<tbody>";
try{
$db = $connection->hospitaldb;
$collection = $db->doctors;
$cursor = $collection->find();
foreach ($cursor as $document)
{
$data .= "<tr>";
$data .= "<td>" . $document["email"] . "</td>";
$data .= "<td>" . $document["password"]."</td>";
$data .= "<td>" . $document["fname"]."</td>";
$data .= "<td>" . $document["lname"]."</td>";
$data .= "</tr>";
}
}catch (MongoException $mongoException)
{
echo "$mongoException";
}
Output :

The question you posted is working for me :
My setup :
php 7.2 thread safe
Downloaded DLL for windows from here https://pecl.php.net/package/mongodb/1.5.3/windows. I put it in ext folder.
Composer.json
"require": {
"mongodb/mongodb": "^1.4"
}
}
Executed php code from your post
<?php
require_once __DIR__ . "/vendor/autoload.php";
$server = "mongodb://localhost:27017/hospitaldb";
try{
$connection = new MongoDB\Client($server);
/*$hospitaldb = $connection->test;*/
$hospitaldb = $connection->hospitaldb;
}catch (MongoConnectionException $ConErrMsg)
{
echo "$ConErrMsg";
}
$data = "<table style='border:1px solid red;";
$data .= "border-collapse:collapse' border='1px'>";
$data .= "<thead>";
$data .= "<tr>";
$data .= "<th>First Name</th>";
$data .= "<th>Last Name</th>";
$data .= "<th>Email</th>";
$data .= "<th>Password</th>";
$data .= "</tr>";
$data .= "</thead>";
$data .= "<tbody>";
try{
$db = $connection->hospitaldb;
$collection = $db->doctors;
$cursor = $collection->find();
foreach ($cursor as $document)
{
$data .= "<tr>";
$data .= "<td>" . $document["first_name"] . "</td>";
$data .= "<td>" . $document["last_name"]."</td>";
$data .= "</tr>";
}
}catch (MongoException $mongoException)
{
echo "$mongoException";
}
var_dump($data);
