  1. Make 3v4l source code Free and Open Source

    I'm sure the community would absolutely love to help out. I know I would.

    • compare performance of 2 snippets (across php/hhvm versions)

      like possible with performance profiles on blackfire.io it would be great to have a comparison view between 2 snippets

      e.g.
      http://3v4l.org/SEW7E/perf#tabs
      vs
      http://3v4l.org/2hdIf/perf#tabs

      • Python equivalent of 3v4l

        Probably a crazy idea that PHP developpers won't care much about but I'd love to be able to run and compare snippets of Python on all the versions/with various interpreters so a 3v4l equivalent for Python would be awesome!

        Among the main implementations : CPython, PyPy, IronPython, Jython.

        As a side-note, if you find this using google, tox is useful to run code on various versions of Python but you obviously need to have them installed.

        • HHVM in php 5 mode

          For HHVM please don't only enable php 7 mode. It's important to test against both php5mode and php7 mode since php 7 mode is still really new and less tested than the default php 5 mode. There are type annotations on internal functions issues with php7 mode currently https://github.com/facebook/hhvm/issues/7198.

          In my testing on travis CI I use latest HHVM and the most recent LTS to get 4 builds
          So currently I have 2 LTS versions (until 3.16 is released)
          - 3.15LTS (php 5 mode)
          - 3.15LTS (php 7 mode)
          - 3.12LTS (php 5 mode)
          - 3.12LTS (php 7 mode)

            • Run HHVM both with and without the JIT on

              HHVM's JIT can be enabled or disabled with -vEval.Jit=true or -vEval.Jit=false, respectively. Could you run each hhvm version twice, once with and once without the JIT on? Any behavioral differences between the two modes are bugs and this would make them more obvious.

              • Add the same versions for different OSs

                Different PHP versions may have different output, but it would be very interesting to know the different outputs for the same (and different) PHP version on different operating systems.

                This code, for example, behaves very differently on some earlier PHP versions on Windows, but it's been the same since the NAN constant was intruduced on Linux:

                <?php

                print "is_numeric(NAN) ? " . (is_numeric(NAN) ? "true\n" : "false\n");
                print "NAN == 0 ? " . (NAN == 0 ? "true\n" : "false\n");
                print "NAN == 1 ? " . (NAN == 1 ? "true\n" : "false\n");
                print "NAN === 0 ?…

                  Would be great to have a compare option where we can have two different scripts for same job to compare all the details, versions, eft, etc.

                  • Explicitely list which php modules are available

                    It seems php-ldap is not available, some other topic suggests that curl is unavailable as well.
                    It would be clearer if you had a list of available php module in the about page.
                    Maybe just show a link to the phpinfo() result for each build?

                    • Run HHVM as a server

                      If you spin up HHVM as a fastcgi server and issue requests to it by doing HTTP GETS for the files in /in/ you would see huge perf wins hopefully. It'll save all the command line warmup.

                      Your server will probably grow unbounded in memory and have to be killed but as long as you have a good restarter it should work. This is how we do unit testing and it sped us up from 10 mins to 1 min.

                      • Add PHP/FI 2.0 as an optional version

                        It's the very first version of PHP you could really call PHP. It wouldn't be terribly useful, mind, but it would certainly be interesting for historical reasons.

                          • Stop trimming ending whitespace

                            This fails because the empty line after EOT heredoc delimiter is trimmed.

                                      • Add HTTP request support

                                        It would be useful for many to be able to fake an incoming HTTP request to said script.

                                        I can't honestly say how easy it would be to implement, sorry.

                                        • Possibly different PHP configurations

                                          Would be nice to apply our own configuration to a specific PHP version and see what does it change with that specific configuration Vs the one that you have here (I.E.: enable/disable OPCache)
