What are some common pitfalls to avoid when transferring array values to a database in PHP?

One common pitfall when transferring array values to a database in PHP is not properly sanitizing the input data, which can lead to SQL injection attacks. To avoid this, always use prepared statements with parameterized queries to securely insert array values into the database. 

// Assuming $array is the array containing values to be inserted into the database

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

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

// Bind parameters and execute the query for each array value
foreach ($array as $value) {
    $stmt->bindParam(':value1', $value['key1']);
    $stmt->bindParam(':value2', $value['key2']);
    $stmt->execute();
}
