What potential issues should be considered when saving SQL data as a text file using PHP?

One potential issue when saving SQL data as a text file using PHP is the risk of SQL injection attacks if the data is not properly sanitized. To prevent this, it is important to use prepared statements or parameterized queries to safely insert data into the text file. 

// Example of using prepared statements to save SQL data as a text file
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

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

// Save the data to a text file
$file = fopen("data.txt", "a");
fwrite($file, $value1 . "\t" . $value2 . "\n");
fclose($file);
