Are there specific guidelines or resources available for PHP developers to learn about secure coding practices and prevent common security issues in their scripts?

One common security issue in PHP scripts is SQL injection, where malicious SQL queries are injected into the code. To prevent this, developers should use prepared statements with parameterized queries. This helps sanitize user input and prevents attackers from executing unauthorized SQL commands. Example PHP code snippet using prepared statements to prevent SQL injection: 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');

// Bind the parameter value
$stmt->bindParam(':username', $_POST['username']);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();
