1. Install the requirements

You need:

XAMPP
PHP 8.2
MongoDB Server
MongoDB PHP Extension (mongodb)
Composer
MongoDB PHP Library

You can verify PHP:

php -v

Check whether MongoDB extension is enabled:

php -m | findstr mongodb

If it shows:

mongodb

the extension is installed correctly.

2. Create the project

Inside XAMPP:

C:\xampp\htdocs\

Create:

product_mongodb

Project structure:

product_mongodb/
│
├── vendor/
├── config.php
├── index.php
├── insert.php
├── edit.php
├── update.php
└── delete.php

3. Install MongoDB PHP Library

Open Command Prompt in the project folder:

cd C:\xampp\htdocs\product_mongodb

Run:

composer require mongodb/mongodb

Composer will create the vendor folder.

if error than

Step 1 — Open the correct `php.ini`

Open:

C:\xampp\php\php.ini

Search for:

;extension=zip

Change it to:

extension=zip

Also make sure MongoDB is enabled. Search for:

extension=mongodb

If it exists and is commented:

;extension=mongodb

4. Create MongoDB database

Start MongoDB server.

Then open MongoDB Shell (mongosh):

mongosh

Create/use database:

use productdb

You don’t actually need to manually create the database or collection. MongoDB will create them when the first product is inserted.

5. Create `config.php`

This file connects PHP to MongoDB.

<?php

require 'vendor/autoload.php';

try {

    $client = new MongoDB\Client("mongodb://localhost:27017");

    $database = $client->productdb;

    $collection = $database->products;

    echo "MongoDB Connected Successfully";

} catch (Exception $e) {

    echo "Connection Failed: " . $e->getMessage();

}

?>

Test it:

http://localhost/product_mongodb/config.php

You should see:

MongoDB Connected Successfully

6. Insert Product

Create insert.php:

<?php

require 'vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");

$db = $client->productdb;

$products = $db->products;

if ($_SERVER["REQUEST_METHOD"] == "POST") {

    $name = $_POST['name'];
    $price = (float)$_POST['price'];
    $quantity = (int)$_POST['quantity'];

    $result = $products->insertOne([
        "name" => $name,
        "price" => $price,
        "quantity" => $quantity
    ]);

    echo "Product inserted successfully!";

}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Add Product</title>
</head>

<body>

<h2>Add Product</h2>

<form method="post">

    Product Name:
    <input type="text" name="name" required>
    <br><br>

    Price:
    <input type="number" name="price" required>
    <br><br>

    Quantity:
    <input type="number" name="quantity" required>
    <br><br>

    <input type="submit" value="Add Product">

</form>

<br>

<a href="index.php">View Products</a>

</body>
</html>

Open:

http://localhost/product_mongodb/insert.php

Example:

Product Name: Laptop
Price: 55000
Quantity: 10

MongoDB document:

{
    name: "Laptop",
    price: 55000,
    quantity: 10
}

7. Display Products

Create index.php:

<?php

require 'vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");

$db = $client->productdb;

$products = $db->products;

$result = $products->find();

?>

<!DOCTYPE html>
<html>

<head>

<title>Product List</title>

</head>

<body>

<h2>Product List</h2>

<a href="insert.php">Add Product</a>

<br><br>

<table border="1" cellpadding="10">

<tr>

    <th>ID</th>
    <th>Name</th>
    <th>Price</th>
    <th>Quantity</th>
    <th>Action</th>

</tr>

<?php

foreach ($result as $product) {

?>

<tr>

<td>
<?php echo $product['_id']; ?>
</td>

<td>
<?php echo $product['name']; ?>
</td>

<td>
<?php echo $product['price']; ?>
</td>

<td>
<?php echo $product['quantity']; ?>
</td>

<td>

<a href="edit.php?id=<?php echo $product['_id']; ?>">
Edit
</a>

&nbsp;

<a href="delete.php?id=<?php echo $product['_id']; ?>"
onclick="return confirm('Are you sure?')">
Delete
</a>

</td>

</tr>

<?php

}

?>

</table>

</body>

</html>

Now visit:

http://localhost/product_mongodb/index.php

You should see your products.

8. Update Product

Create edit.php:

<?php

require 'vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");

$db = $client->productdb;

$products = $db->products;

$id = new MongoDB\BSON\ObjectId($_GET['id']);

$product = $products->findOne([
    '_id' => $id
]);

?>

<!DOCTYPE html>

<html>

<head>

<title>Edit Product</title>

</head>

<body>

<h2>Edit Product</h2>

<form action="update.php" method="post">

<input type="hidden"
       name="id"
       value="<?php echo $product['_id']; ?>">

Product Name:

<input type="text"
       name="name"
       value="<?php echo $product['name']; ?>">

<br><br>

Price:

<input type="number"
       name="price"
       value="<?php echo $product['price']; ?>">

<br><br>

Quantity:

<input type="number"
       name="quantity"
       value="<?php echo $product['quantity']; ?>">

<br><br>

<input type="submit" value="Update Product">

</form>

</body>

</html>

9. Create `update.php`

<?php

require 'vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");

$db = $client->productdb;

$products = $db->products;

$id = new MongoDB\BSON\ObjectId($_POST['id']);

$name = $_POST['name'];

$price = (float)$_POST['price'];

$quantity = (int)$_POST['quantity'];

$products->updateOne(

    ['_id' => $id],

    [
        '$set' => [
            'name' => $name,
            'price' => $price,
            'quantity' => $quantity
        ]
    ]

);

header("Location: index.php");

exit;

?>

10. Delete Product

Create delete.php:

<?php

require 'vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");

$db = $client->productdb;

$products = $db->products;

$id = new MongoDB\BSON\ObjectId($_GET['id']);

$products->deleteOne([
    '_id' => $id
]);

header("Location: index.php");

exit;

?>

CRUD operations

Operation	PHP/MongoDB method
Create	`insertOne()`
Read	`find()` / `findOne()`
Update	`updateOne()`
Delete	`deleteOne()`

MongoDB structure

productdb
   |
   └── products
        |
        ├── _id
        ├── name
        ├── price
        └── quantity

If you want the same Product CRUD example using MongoDB\Driver\Manager instead of MongoDB\Client, you can do it using the lower-level MongoDB PHP Driver.

Important: MongoDB\Driver\Manager comes from the PHP MongoDB extension, not from the Composer mongodb/mongodb library. So php --ri mongodb must work first.

1. Check MongoDB extension

Run:

php --ri mongodb

You should see something like:

MongoDB extension version => 1.x.x

Then:

php -m | findstr /i mongodb

Expected:

mongodb

2. Product Database Structure

We’ll use:

Database:  productdb
Collection: products

A product document will look like:

{
    _id: ObjectId("..."),
    name: "Laptop",
    price: 55000,
    quantity: 10
}

3. MongoDB Manager Connection

Create:

config.php

<?php

try {

    $manager = new MongoDB\Driver\Manager(
        "mongodb://localhost:27017"
    );

    echo "MongoDB Connected Successfully";

} catch (MongoDB\Driver\Exception\Exception $e) {

    echo "Connection Failed: " . $e->getMessage();

}

?>

Run:

http://localhost/product_mongodb/config.php

You should get:

MongoDB Connected Successfully

4. Insert Product

Create:

insert.php

<?php

$manager = new MongoDB\Driver\Manager(
    "mongodb://localhost:27017"
);

if ($_SERVER["REQUEST_METHOD"] == "POST") {

    $name = $_POST["name"];
    $price = (float) $_POST["price"];
    $quantity = (int) $_POST["quantity"];

    $bulk = new MongoDB\Driver\BulkWrite();

    $bulk->insert([
        "name" => $name,
        "price" => $price,
        "quantity" => $quantity
    ]);

    try {

        $result = $manager->executeBulkWrite(
            "productdb.products",
            $bulk
        );

        echo "Product inserted successfully!";

    } catch (MongoDB\Driver\Exception\Exception $e) {

        echo "Error: " . $e->getMessage();

    }
}

?>

<!DOCTYPE html>
<html>

<head>
    <title>Add Product</title>
</head>

<body>

<h2>Add Product</h2>

<form method="post">

    Product Name:
    <input type="text" name="name" required>

    <br><br>

    Price:
    <input type="number" name="price" required>

    <br><br>

    Quantity:
    <input type="number" name="quantity" required>

    <br><br>

    <input type="submit" value="Add Product">

</form>

<br>

<a href="index.php">View Products</a>

</body>

</html>

Important Manager concept

The main code is:

$bulk = new MongoDB\Driver\BulkWrite();

$bulk->insert([
    "name" => $name,
    "price" => $price,
    "quantity" => $quantity
]);

$manager->executeBulkWrite(
    "productdb.products",
    $bulk
);

5. Display Products

Create:

index.php

<?php

$manager = new MongoDB\Driver\Manager(
    "mongodb://localhost:27017"
);

$query = new MongoDB\Driver\Query([]);

try {

    $rows = $manager->executeQuery(
        "productdb.products",
        $query
    );

} catch (MongoDB\Driver\Exception\Exception $e) {

    die("Error: " . $e->getMessage());

}

?>

<!DOCTYPE html>

<html>

<head>

<title>Product List</title>

</head>

<body>

<h2>Product List</h2>

<a href="insert.php">Add Product</a>

<br><br>

<table border="1" cellpadding="10">

<tr>

    <th>ID</th>
    <th>Name</th>
    <th>Price</th>
    <th>Quantity</th>
    <th>Action</th>

</tr>

<?php

foreach ($rows as $product) {

?>

<tr>

<td>
<?php echo $product->_id; ?>
</td>

<td>
<?php echo $product->name; ?>
</td>

<td>
<?php echo $product->price; ?>
</td>

<td>
<?php echo $product->quantity; ?>
</td>

<td>

<a href="edit.php?id=<?php echo $product->_id; ?>">
Edit
</a>

|

<a href="delete.php?id=<?php echo $product->_id; ?>"
   onclick="return confirm('Delete this product?');">
Delete
</a>

</td>

</tr>

<?php

}

?>

</table>

</body>

</html>

Here we use:

new MongoDB\Driver\Query([])

and:

$manager->executeQuery()

to retrieve documents.

6. Edit Product

Create:

edit.php

<?php

$manager = new MongoDB\Driver\Manager(
    "mongodb://localhost:27017"
);

$id = new MongoDB\BSON\ObjectId($_GET["id"]);

$filter = [
    "_id" => $id
];

$query = new MongoDB\Driver\Query($filter);

$rows = $manager->executeQuery(
    "productdb.products",
    $query
);

$product = current($rows);

?>

<!DOCTYPE html>

<html>

<head>

<title>Edit Product</title>

</head>

<body>

<h2>Edit Product</h2>

<form action="update.php" method="post">

<input type="hidden"
       name="id"
       value="<?php echo $product->_id; ?>">

Product Name:

<input type="text"
       name="name"
       value="<?php echo $product->name; ?>"
       required>

<br><br>

Price:

<input type="number"
       name="price"
       value="<?php echo $product->price; ?>"
       required>

<br><br>

Quantity:

<input type="number"
       name="quantity"
       value="<?php echo $product->quantity; ?>"
       required>

<br><br>

<input type="submit"
       value="Update Product">

</form>

</body>

</html>

7. Update Product

Create:

update.php

<?php

$manager = new MongoDB\Driver\Manager(
    "mongodb://localhost:27017"
);

$id = new MongoDB\BSON\ObjectId(
    $_POST["id"]
);

$name = $_POST["name"];

$price = (float) $_POST["price"];

$quantity = (int) $_POST["quantity"];

$bulk = new MongoDB\Driver\BulkWrite();

$bulk->update(

    [
        "_id" => $id
    ],

    [
        '$set' => [
            "name" => $name,
            "price" => $price,
            "quantity" => $quantity
        ]
    ]

);

try {

    $manager->executeBulkWrite(
        "productdb.products",
        $bulk
    );

    header("Location: index.php");

    exit;

} catch (MongoDB\Driver\Exception\Exception $e) {

    echo "Update Error: " . $e->getMessage();

}

?>

8. Delete Product

Create:

delete.php

<?php

$manager = new MongoDB\Driver\Manager(
    "mongodb://localhost:27017"
);

$id = new MongoDB\BSON\ObjectId(
    $_GET["id"]
);

$bulk = new MongoDB\Driver\BulkWrite();

$bulk->delete([
    "_id" => $id
]);

try {

    $manager->executeBulkWrite(
        "productdb.products",
        $bulk
    );

    header("Location: index.php");

    exit;

} catch (MongoDB\Driver\Exception\Exception $e) {

    echo "Delete Error: " . $e->getMessage();

}

?>

9. Complete Project

Your folder will be:

product_mongodb/
│
├── config.php
│
├── index.php
│
├── insert.php
│
├── edit.php
│
├── update.php
│
└── delete.php

No Composer library is required for this version if the MongoDB PHP extension is installed.

10. Manager CRUD Methods

For your students, the important part is this:

Operation	MongoDB Manager class
Connection	`MongoDB\Driver\Manager`
Insert/Update/Delete	`MongoDB\Driver\BulkWrite`
Read	`MongoDB\Driver\Query`
Execute Read	`$manager->executeQuery()`
Execute Write	`$manager->executeBulkWrite()`
ID	`MongoDB\BSON\ObjectId`

Simple flow

PHP
 │
 ▼
MongoDB\Driver\Manager
 │
 ├── executeQuery()
 │       │
 │       └── Read Products
 │
 └── executeBulkWrite()
         │
         ├── insert()
         ├── update()
         └── delete()

Most important connection line

$manager = new MongoDB\Driver\Manager(
    "mongodb://localhost:27017"
);

This is the MongoDB Manager approach, unlike the previous example:

$client = new MongoDB\Client(
    "mongodb://localhost:27017"
);

For your current setup, Manager is a good choice for teaching the MongoDB PHP Driver directly, because students can clearly see Manager, Query, BulkWrite, and ObjectId classes.
