Remove foreach loop in demo.php

[BaylorRae]

The glob() function can expand arguments within curly braces. This allows you write the following.

$files = glob('*.{png,jpg,jpeg}', GLOB_BRACE);

The above code will find all files in the current directory that have an image extension without using a foreach loop.

Fair call. I would have used a similar solution had I known about it at the time.
I support this Pull Request.

@lucanos the feature is somewhat hidden. I only found it on accident a few months ago.
