How to Validate Login from MySQLi Database Using PHP and Allow Access if Passwords Match

Validating Login from MySQLi Database Using PHP

When it comes to implementing a secure login system in web development, validating user credentials against a MySQL database is a common practice. In this article, we will discuss how to securely validate login from a MySQLi database using PHP and only allow access if the passwords match.

Steps to Validate Login and Match Passwords:

1. Establish a connection to the MySQL database using MySQLi in PHP.
2. Query the database to fetch the user's stored password based on the entered username.
3. Compare the hashed password from the database with the hashed password entered by the user during login.
4. If the passwords match, allow the user to access the system; otherwise, deny access.

It's crucial to properly hash passwords before storing them in the database using a secure hashing algorithm like bcrypt. Additionally, always use prepared statements to prevent SQL injection attacks when interacting with the database.
