What are the potential performance implications of using fwrite to log data in a CSV file as the file size grows in PHP?

Using fwrite to log data in a CSV file in PHP can lead to performance issues as the file size grows because fwrite writes data to the file sequentially. As the file size increases, writing to the file becomes slower, especially if the file needs to be read and written to frequently. To improve performance, consider using a database to store and retrieve data instead of writing directly to a CSV file. 

// Example code snippet using a database to log data instead of writing to a CSV file
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Insert data into database
$data = "Data to log";
$sql = "INSERT INTO logs (data) VALUES ('$data')";

if ($conn->query($sql) === TRUE) {
    echo "Data logged successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// Close connection
$conn->close();
