PHP Development Team Announces PHP 7.0.0 Alpha 2

from the almost-ready dept.

DarkMorph writes:

Although the first alpha build of PHP7 was released just two weeks ago, the second build is already being rolled out. A variety of issues from 5.6 have been fixed as part of version 7's alpha build, and a rather comprehensive overview of new features and other language changes have been posted on PHP's official GitHub repository. Some of the most notable improvements are the boasted performance enhancement over PHP5.6, claimed to be up to twice as fast on 64-bit systems, and the well-debated inclusion of scalar type hints.

Additional history of the drafted and implemented changes for version 7 can be seen at the PHP Request for Comments Wiki.

    A client asked me to figure out why his server kept crashing. Youre running out of swap spave because of memory leaks in your java app. But thats not possible java has garbage collection. That because suns marketing people lied to you.

    I set up a cron to reboot every night.

    Bjarne intended for c++ to solve many problems but for that to happen you have to write c++ the way it is meant to be written.

    mike whats that there in your source. its an initialization list. whats that? it enables transactional commit rollback object initialization.

    100 programmer years in a single executable and they had never even heard of initialization lists.

    Mentor Graphics adopted c++ because object oriented code is reusable. what they got was a clusterfuck. good assembly is reusable but bad c++ is not.

    Did anyone from Sun ever actually claim that memory leaks are "impossible" in Java (as opposed to "much less likely")? Or did you just make that up?

      I dont know about sun specifically but java fans iften make that claim.

      optimize-it was a java leak detector that borland sold for thousands of dollars per license.

      i dont regard java as being less likely than C++ to leak. it's easy to write leak free c++.

          not that one cannot write leak free java but that java is harder to get right.

            funny. so which bit of that would cover "it's easy to write leak free c++"? operative word being "easy". because "easy" does not mean "this really is a complicated and detailed topic, and I worry that I will scare away beginners." which is from your own intro.

          It actually is much easier to write leak-free C++ with C++14 than it used to be. Basically, never keep bare pointers around and, if you're allocating objects on the heap, always use std::make_unique or std::make_shared. Avoid cyclic data structures (this is probably the hardest. When you have to have cycles, explicitly break them with std::weak_ptr).

            interesting, i havent been keeping up with c++ (all my experience is pre c++11) so i hadnt come across those make_ functions before. thanks.

              If you haven't looked at C++ since before C++11, then I'd suggest taking another detailed look. The language now doesn't completely suck. It's now possible to write quite nice code in C++ (the problems with ABI fragility are still there, sadly). With shared_ptr and unique_ptr, lambdas, the threading and atomics libraries, it has many of the features that you actually want from a modern language. I've gone from hating C++ to tolerating it and using it as my default language for new projects as a result. There's absolutely no way that I'd contribute to a pre-C++11 codebase now though.
