Laravel - Collections - Creating Lazy Collections

To create a lazy collection instance, you should pass a PHP generator function to the collection's make method:

    
    use Illuminate\Support\LazyCollection;
    
    LazyCollection::make(function () {
        $handle = fopen('log.txt', 'r');
    
        while (($line = fgets($handle)) !== false) {
            yield $line;
        }
    });
