What are common pitfalls when passing multiple values to a MySQL database using PHP?

One common pitfall when passing multiple values to a MySQL database using PHP is not properly sanitizing the input data, which can lead to SQL injection attacks. To solve this issue, it is important to use prepared statements with parameterized queries to securely pass values to the database. 

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

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

// Bind the values to the placeholders
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

// Set the values
$value1 = "example1";
$value2 = "example2";

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