PHP CRUD Operations

PHP CRUD with MySQLi or PDO

PHP CRUD operations use prepared statements for MySQL.

Introduction to CRUD Operations

CRUD stands for Create, Read, Update, and Delete. These are the four basic operations for managing data in a database. In this guide, we'll explore how to implement these operations in PHP using MySQL prepared statements, which help prevent SQL injection and improve performance.

Setting Up the Database and Connection

Before implementing CRUD operations, you need a MySQL database and a table. Below is an example SQL statement to create a simple 'users' table:

Next, establish a connection to your MySQL database using PHP's mysqli extension:

Create Operation

The Create operation involves inserting a new record into the database. Here's how you can do this using a prepared statement:

Read Operation

The Read operation retrieves records from the database. Below is an example of how to fetch all users:

Update Operation

The Update operation modifies existing records. Here's how to update a user's email:

Delete Operation

The Delete operation removes records from the database. Here's an example of deleting a user:

Closing the Database Connection

After performing the CRUD operations, it's important to close the database connection to free resources:

Conclusion

In this tutorial, we covered the basics of PHP CRUD operations using prepared statements with MySQL. These operations are fundamental for any data-driven application. Remember to always use prepared statements to ensure your application is secure against SQL injection attacks.
