What are some potential pitfalls when splitting text data from a file into database records using PHP?

One potential pitfall when splitting text data from a file into database records using PHP is not properly sanitizing the input data, which can lead to SQL injection attacks. To prevent this, it's important to use prepared statements and parameterized queries when interacting with the database. 

// Sample code snippet using prepared statements to insert data into a database

// Assuming $data contains the text data to be split and inserted into the database

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

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

// Loop through the data and insert each record into the database
foreach ($data as $record) {
    // Bind the values to the placeholders and execute the statement
    $stmt->bindParam(':value1', $record['value1']);
    $stmt->bindParam(':value2', $record['value2']);
    $stmt->execute();
}
