What are common pitfalls when using INSERT INTO queries in PHP?

One common pitfall when using INSERT INTO queries in PHP is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely insert data into your database. 

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare the INSERT statement
$stmt = $pdo->prepare("INSERT INTO mytable (column1, column2) VALUES (:value1, :value2)");

// Bind parameters
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

// Set parameter values
$value1 = $_POST['input1'];
$value2 = $_POST['input2'];

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