What are some recommended tools or libraries for handling file and database backups in PHP?

Handling file and database backups in PHP is essential for ensuring data integrity and disaster recovery. One way to achieve this is by using tools or libraries that automate the backup process, making it easier to schedule and manage backups efficiently. One recommended tool for handling file backups in PHP is the "ZipArchive" class, which allows you to create zip archives of files and directories. For database backups, you can use libraries like "PDO" or "mysqli" to connect to the database and export the data to a file. 

// Example of using ZipArchive to create a file backup
$zip = new ZipArchive();
$zip->open('backup.zip', ZipArchive::CREATE);
$files = ['file1.txt', 'file2.txt', 'directory1'];
foreach ($files as $file) {
    if (is_file($file)) {
        $zip->addFile($file);
    } elseif (is_dir($file)) {
        $zip->addEmptyDir($file);
    }
}
$zip->close();

// Example of using PDO to create a database backup
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM mytable');
$stmt->execute();
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
file_put_contents('backup.sql', var_export($data, true));
