How can you troubleshoot the "stat failed" error when using filesize() in PHP?

The "stat failed" error in PHP occurs when the filesize() function is unable to retrieve the file size due to permission issues or the file not existing. To troubleshoot this error, you can check if the file exists and if the PHP script has the necessary permissions to access the file. 

$file = 'example.txt';

if (file_exists($file) && is_readable($file)) {
    $fileSize = filesize($file);
    echo "File size: $fileSize bytes";
} else {
    echo "Error: Unable to retrieve file size. Check file permissions or if the file exists.";
}
