Our second #ossart entry is dedicated to Stack PHP, a PHP middleware reference implementation by Igor Wiedler, Beau Simensen, and Christoph Hochstrasser.
We sent a few teaser images out on Twitter (you're following #ossart, right?) and we got a few guesses! The first person to correctly guess the project this time around was @mwop! Nicely done!
Now that PSR-7 under review, Stack PHP may soon be undergoing a transformation into something... different. Follow @stackphp to learn more!
Prints include white border and are titled under the image. They are printed on Somerset Enhanced Velvet Fine Art Paper, which is an acid-free, 100% cotton paper with natural white finish and a soft-textured matte surface.
