php-vfs

You write your php to a file in the vfs, then you `require` it back out. There's an example of it in the documentation[1] but a simple example could be: ``` <?php FileSystem::factory('vfs://'); file_put_contents('vfs://foo.php', '<?php echo "Hello, World!";'); require 'vfs://foo.php'; // Hello, World! ``` [1]: https://github.com/adlawson/vfs.php#documentation

On the surface of it, there is no real difference. You can use them both with your usual `fopen` and `file_get_contents` builtins. I believe that the implementation is truer to the behaviour of how these builtin functions behave with a unix FS. Amongst some other subtleties, here's some examples: - vfsStream simply ignores handle modifiers (except for +)[1] - some effort has gone into showing where errors were triggered in userland code[2] - node types are represented as `fstat` would see them[3] rather than using simple types[4] vfsStream works perfectly fine, but if you want to use it more with testing file system operations; the closer you are to a true environment the better. Obviously this project isn't quite there yet, but it should be once a few issues have been ironed out. [1]: https://github.com/mikey179/vfsStream/blob/master/src
