How can developers test their PHP scripts for vulnerabilities to SQL Injections?
Developers can test their PHP scripts for vulnerabilities to SQL Injections by using prepared statements with parameterized queries. This method helps prevent malicious SQL Injection attacks by separating SQL code from user input. By binding parameters to SQL queries, developers can ensure that input data is treated as data and not executable code.
// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
// Bind parameters to the query
$stmt->bindParam(':username', $_POST['username']);
$stmt->execute();
// Fetch results
$results = $stmt->fetchAll();
