Learn how to connect to MongoDB databases in Sealos DevBox using PHP
This guide will walk you through the process of connecting to a MongoDB database using PHP within your Sealos DevBox project.
Prerequisites
- A Sealos DevBox project with PHP environment
- A MongoDB database created using the Database app in Sealos
Install Required Extensions
In your Cursor terminal, ensure that the MongoDB extension for PHP is installed:
Install the MongoDB PHP Library
To install the MongoDB PHP Library, run the following command in your php-quickstart directory:
Connection Setup
Create a Configuration File
First, let's create a configuration file to store our database connection parameters. Create a file named config.php
in your project directory with the following content:
Replace the placeholders with your actual MongoDB credentials from the Database app in Sealos.
Create a Database Connection Function
Next, let's create a PHP file that will handle the database connection. Create a file named db_connect.php
with the following content:
This function reads the configuration from config.php
and establishes a connection to the MongoDB database.
Create a Test Script
Now, let's create a test script to verify our connection and perform some basic database operations. Create a file named test_mongodb.php
with the following content:
Usage
To run the test script, use the following command in your Cursor terminal:
This will execute the script, demonstrating the connection to the database, document insertion, querying, updating, and deletion.
Best Practices
- Use environment variables or a separate configuration file for database credentials.
- Always handle potential errors using try-catch blocks.
- Use the MongoDB PHP library for better performance and features.
- Close the database connection after operations are complete (in this case, it's handled automatically).
- Use appropriate indexing for frequently queried fields to improve performance.
Troubleshooting
If you encounter connection issues:
- Verify your database credentials in the
config.php
file. - Ensure your MongoDB database is running and accessible.
- Check for any network restrictions in your DevBox environment.
- Confirm that the MongoDB PHP extension is correctly installed.
