Are there specific PHP functions or methods that can automate the process of loading and querying data from multiple backup files?

To automate the process of loading and querying data from multiple backup files in PHP, you can use functions like `glob()` to retrieve a list of backup files, loop through them, and extract the data using methods like `file_get_contents()` or `fopen()`. You can then process the data accordingly using SQL queries or other data manipulation functions.

$backupFiles = glob('path/to/backup/*.sql');

foreach ($backupFiles as $file) {
    $data = file_get_contents($file);
    
    // Process the data (e.g. execute SQL queries)
    // Example: $result = mysqli_query($connection, $data);
}
