Question

How can PHP be used to create a secure web application to prevent SQL injection

Answer 1

SQL injection is one of the most common vulnerabilities, but it’s super easy to prevent in PHP by using prepared statements. 

Here’s how:

How it works:

• prepare(): Prepares an SQL statement with placeholders (?) where user input goes.
• bind_param(): Binds the actual user input to the placeholders, ensuring the input can’t mess with the query.

By using prepared statements like this, you’re preventing malicious input from affecting your SQL query, which stops SQL injections.
