What are the potential risks of not using addslashes() in PHP code?

Not using addslashes() in PHP code can leave your application vulnerable to SQL injection attacks, where malicious users can manipulate database queries. To prevent this, you should always use addslashes() to escape special characters before inserting user input into SQL queries. 

// Using addslashes() to escape special characters before inserting user input into SQL queries
$name = addslashes($_POST['name']);
$email = addslashes($_POST['email']);

$query = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
$result = mysqli_query($connection, $query);

// Remember to use prepared statements or parameterized queries for better security
