Are there any specific PHP functions that can help prevent SQL injections when working with form data?

SQL injections can be prevented by using prepared statements with parameterized queries when interacting with a database in PHP. This helps sanitize user input and prevents malicious SQL queries from being executed. The `mysqli` or `PDO` extensions in PHP provide functions for prepared statements that can help mitigate the risk of SQL injection attacks. 

// Using prepared statements with mysqli
$conn = new mysqli($servername, $username, $password, $dbname);
$stmt = $conn->prepare("INSERT INTO users (username, password) VALUES (?, ?)");
$stmt->bind_param("ss", $username, $password);

// Sanitize user input before binding parameters
$username = mysqli_real_escape_string($conn, $_POST['username']);
$password = password_hash($_POST['password'], PASSWORD_DEFAULT);

$stmt->execute();
$stmt->close();
$conn->close();
