How can one ensure that changes made to text files in PHP are saved and maintained accurately without data loss or corruption?

To ensure changes made to text files in PHP are saved accurately without data loss or corruption, it is important to properly open the file in write mode, make the necessary modifications, and then close the file to save the changes. Additionally, using error handling mechanisms like try-catch blocks can help in detecting and handling any potential issues that may arise during the file writing process. 

<?php
$filename = 'example.txt';

try {
    $file = fopen($filename, 'w');
    if ($file === false) {
        throw new Exception('Error opening file');
    }

    fwrite($file, "New content to be added to the file\n");

    fclose($file);
    echo "Changes saved successfully.";
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
?>
