What potential issue is the user facing when trying to write content to a file using PHP?

The potential issue the user may face when trying to write content to a file using PHP is file permissions. If the file does not have the correct permissions set, PHP may not be able to write to it. To solve this issue, the user should ensure that the file has write permissions enabled for the PHP process. 

$file = 'example.txt';
$content = "Hello, World!";
if (is_writable($file)) {
    file_put_contents($file, $content);
    echo "Content written to file successfully.";
} else {
    echo "File is not writable. Please check file permissions.";
}
