What are some best practices for efficiently processing a large number of files in PHP?

When processing a large number of files in PHP, it is important to use efficient methods to avoid memory and performance issues. One way to do this is by using iterators, which allow you to process files one at a time without loading them all into memory at once. Additionally, consider using functions like `glob()` or `scandir()` to efficiently retrieve a list of files to process. 

// Example of efficiently processing a large number of files using iterators
$files = new FilesystemIterator('/path/to/directory');

foreach ($files as $file) {
    // Process each file here
    echo $file->getFilename() . "\n";
}
