What are some recommended PHP functions for scanning and deleting files in a specific directory?

When working with files in a specific directory in PHP, it is important to be able to scan the directory for files and then delete them if needed. Two recommended PHP functions for this task are `scandir()` to scan the directory and `unlink()` to delete files. 

// Scan a specific directory for files
$directory = '/path/to/directory';
$files = scandir($directory);

// Loop through the files and delete them
foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        unlink($directory . '/' . $file);
    }
}
