How can logging be implemented to store and display previous update messages in PHP?

To implement logging to store and display previous update messages in PHP, you can use the built-in `error_log()` function to write messages to a log file. You can then read and display these messages by reading the log file and outputting its contents. 

// Log the update message
$message = "User updated profile information";
error_log($message . PHP_EOL, 3, "update_log.txt");

// Display previous update messages
$logFile = "update_log.txt";
if (file_exists($logFile)) {
    $logContent = file_get_contents($logFile);
    echo nl2br($logContent);
} else {
    echo "No update messages found.";
}
