What are the potential pitfalls of using INSERT INTO in PHP when inserting data into a database?

Potential pitfalls of using INSERT INTO in PHP when inserting data into a database include SQL injection attacks if user input is not properly sanitized. To prevent this, it is important to use prepared statements with parameterized queries to safely insert data into the database. 

// Using prepared statements to insert data safely into a database

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

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

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

// Execute the statement with the actual values
$value1 = "some value";
$value2 = "another value";
$stmt->execute();
