What are common pitfalls when using PHP to read and store emails in a MySQL database?

One common pitfall when using PHP to read and store emails in a MySQL database is not properly sanitizing input data, which can lead to SQL injection attacks. To prevent this, always use prepared statements when interacting with the database to ensure that user input is properly escaped. 

// Connect to the database
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

// Prepare a statement to insert email data into the database
$stmt = $mysqli->prepare("INSERT INTO emails (subject, body) VALUES (?, ?)");

// Bind parameters and execute the statement
$stmt->bind_param("ss", $subject, $body);
$subject = $_POST['subject'];
$body = $_POST['body'];
$stmt->execute();

// Close the statement and database connection
$stmt->close();
$mysqli->close();
