What potential pitfalls should be considered when inserting data from an array into a database in PHP?

One potential pitfall to consider when inserting data from an array into a database in PHP is the risk of SQL injection if the data is not properly sanitized. To mitigate this risk, always use prepared statements with parameterized queries to ensure that user input is treated as data and not executable code. 

// Assuming $data is the array containing the data to be inserted
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

foreach ($data as $row) {
    $stmt->execute([
        'value1' => $row['value1'],
        'value2' => $row['value2']
    ]);
}
