What are the potential pitfalls of storing mysql query results in a text file in PHP?

Storing MySQL query results in a text file in PHP can lead to security vulnerabilities if the text file is not properly secured. It may also result in data inconsistency if the text file is not updated in sync with the database. To mitigate these risks, it is recommended to properly sanitize the data before storing it in the text file and ensure that the text file is securely stored and accessed. 

// Example of securely storing MySQL query results in a text file in PHP

// Perform MySQL query
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);

// Open a file for writing
$filename = 'query_results.txt';
$file = fopen($filename, 'w');

// Write query results to the text file
while ($row = mysqli_fetch_assoc($result)) {
    fwrite($file, implode(',', $row) . PHP_EOL);
}

// Close the file
fclose($file);
