How can PHP developers improve the security and reliability of their scripts when dealing with file extraction processes like unrar?

To improve the security and reliability of file extraction processes like unrar in PHP, developers should validate user input to prevent directory traversal attacks, sanitize file names to avoid potential vulnerabilities, and use secure libraries or functions for file extraction operations. 

// Example code snippet for secure file extraction using PHP's ZipArchive class

$zipFile = 'example.zip';
$extractPath = 'extracted_files/';

$zip = new ZipArchive;
if ($zip->open($zipFile) === TRUE) {
    $zip->extractTo($extractPath);
    $zip->close();
    echo 'Files extracted successfully.';
} else {
    echo 'Failed to extract files.';
}
