How can one troubleshoot issues with writing data to a file using PHP?

To troubleshoot issues with writing data to a file using PHP, you can check for proper file permissions, ensure the file path is correct, and handle any errors that may occur during the writing process. Additionally, you can use functions like fopen(), fwrite(), and fclose() to properly write data to a file. 

<?php
$file = 'data.txt';
$data = 'Hello, World!';

$handle = fopen($file, 'w');
if ($handle === false) {
    die('Cannot open file for writing');
}

if (fwrite($handle, $data) === false) {
    die('Cannot write to file');
}

fclose($handle);
echo 'Data written to file successfully';
?>
