What are the potential security risks associated with using PHP scripts to export data from MySQL databases?

Potential security risks associated with using PHP scripts to export data from MySQL databases include SQL injection attacks, data leakage, and unauthorized access to sensitive information. To mitigate these risks, it is essential to properly sanitize user input, use parameterized queries, and restrict access to the database credentials. 

// Example of using parameterized queries to export data from MySQL database securely

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

// Prepare a statement with a parameterized query
$stmt = $pdo->prepare("SELECT * FROM mytable WHERE id = :id");

// Bind the parameter value
$stmt->bindParam(':id', $id);

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

// Fetch the results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Export the data as needed
foreach ($results as $row) {
    // Export data here
}
