Why shouldn"t I use mysql_* functions in PHP?

😱 Why shouldn't I use mysql_* functions in PHP?

So you've stumbled upon the question of why you shouldn't use those mysql_* functions in PHP. Good for you because it's important to understand the reasons behind it! 🙌

🧐 Understanding the problem

The technical reasons for avoiding mysql_* functions, such as mysql_query(), mysql_connect(), or mysql_real_escape_string(), stem from a shift in PHP's database extension.

Before PHP 5.5.0, the standard extension used for interacting with MySQL databases was the MySQL extension, which offered these mysql_* functions. However, this extension has been deprecated since PHP 5.5.0 and is no longer actively maintained. Deprecated means it's no longer recommended and could be removed in future versions of PHP.

❌ Why you should avoid mysql_* functions

Using mysql_* functions poses several issues that you should definitely know about:

1. Security vulnerabilities: The mysql_* functions don't support prepared statements or parameterized queries, making it harder to prevent SQL injection attacks. SQL injection occurs when malicious inputs are inserted into database queries, potentially causing unauthorized access to or modification of your database.

2. Outdated technology: As mentioned earlier, the mysql_* functions are part of a deprecated extension. Deprecated things are like old cassettes—soon, you won't find players for them anymore. It's best to keep up with current technologies and use the improved alternatives.

3. No support or bug fixes: Deprecated things are not maintained or updated regularly. If you encounter any bugs or issues with mysql_* functions, there won't be any official support available to help you out.

4. Compatibility concerns: As versions of PHP progress, it's likely that mysql_* functions will be completely removed. Upgrading your PHP version might cause your code to break, leaving you with more problems to solve.

🛠️ The better alternatives

To future-proof your code and ensure a more secure and reliable application, here are a couple of awesome alternatives to mysql_* functions:

1. MySQLi: This extension stands for MySQL Improved and offers an object-oriented interface, prepared statements, and enhanced security features. It's the recommended replacement for mysql_* functions.

   Example code snippet using MySQLi:

   $mysqli = new mysqli("localhost", "username", "password", "database"); $result = $mysqli->query("SELECT * FROM users");

2. PDO: PDO stands for PHP Data Objects and provides a consistent interface for accessing different databases, including MySQL. It also supports prepared statements and offers superior error handling.

   Example code snippet using PDO:

   $pdo = new PDO("mysql:host=localhost;dbname=database", "username", "password"); $stmt = $pdo->prepare("SELECT * FROM users"); $stmt->execute();

💪 Take action now!

Now that you understand why using mysql_* functions is a bad idea, it's time to take action! Here's what you can do:

1. Check your codebase: Search for any occurrences of mysql_* functions in your project. Update them to either MySQLi or PDO equivalents.

2. Learn the alternatives: Familiarize yourself with how to use MySQLi or PDO for database interactions. Dive into their documentation, find tutorials, and practice using them in small, controlled projects.

3. Share your knowledge: Tell your developer friends about the pitfalls of mysql_* functions and encourage them to switch to the better alternatives. Sharing is caring, and it benefits the entire community!

Remember, using up-to-date and secure technologies not only protects you from potential issues but also improves the performance and maintainability of your codebase. Don't get left behind! 😎
