Take only file name from input and use it.
// Use basename() to extract only the filename, preventing directory traversal. and use it in the next lines
$safeFileName = basename(logFileName);

// Construct the full path.

$fullPath = realpath($baseDir . $safeFileName);
// Validate: Ensure the path is within the intended directory.
