An Early Look At What's Coming In PHP V6

IndioMan writes "In this article, learn about the new PHP V6 features in detail. Learn how it is easier to use, more secure, and more suitable for internationalization. New PHP V6 features include improved support for Unicode, clean-up of several functions, improved extensions, engine additions, changes to OO functions, and PHP additions." Update — May 7th at 16:47 GMT by SS: IBM seems to have removed the article linked in the summary. Here's a different yet related article about the future of PHP, but it's a year old.

      At my work we host and have build and maintain a little over 200 php websites. We host them all ourselves. ( the CMS that we use is build in PHP )

      We earn money from both the hosting and the developing.

      Many of our customers don't want to pay for the porting of their websites to PHP5, let alone PHP6. usually this requires upgrading the CMS as well, making modifications to custom extentions written by outsourcing partys, etc. All in all quite expensive for the site owner.

      "Threatening" them with PHP4 server shutdowns only makes them go away to other hosting providers that will over PHP4 to them.

      So we ended up virtualising all the PHP4 sites together with a good backup system and making our customers understand that we provide no warrenty anymore. We will help them when things blow up on an paid per hour basis.

      Another problem is that we cannot reuse a lot of our code anymore now. Many of our new plugins require php5 so we have to modify them to make them php4 compatible again.

      when php6 comes out we will have to support three different php versions... the horrors of that vision already scare me today..

      2. customer complains that he paid for his site and that he expects it to just work.

      3. we explain that our knowledge of what will happen to future versions of the product is rather limited and that we therefore in principle can only make the best dessisions at a given time, that we regret the problems, but cannot help it. we then usually evaluate the components that are used in the website, CMS version, modules, tweaks, how much was done by outsourcing, etc and send it of to the customer.

      4. customers views the estimate and nearly dies from a heart attack when he sees what it will cost to port his website to a new php version without any increase in function.

      5. if we were lucky in fase 3 / 4 we have been able to get him addicted to some additional services as well that "only work with php5" making the upgrade path somewhat worth it. If that fails the customer in 90% of the cases won't think the upgrade path is worth it and will arange with us that we will keep hosting the site but without warrenty.

      You're not far off track. A lot of PHP's problems stems from the fact that the language itself was more or less kind of thrown together rather than planned out (from the early simple Personal Home Page scripting stuff to PHP3 that just kept extending things and adding more functionality bolted on). They only just began to start to stabalize some of that in PHP4 and really only started to fix a lot of issues in PHP5 and now PHP6. They are making good strides but there's a lot of work to do (and a lot of backwards compatible considerations, I'm sure).

Stuff that is going away has been deprecated for many versions now so none of this should be a surprise.

    Given that PHP 6 was "rumored" to be out at least a year ago. I can't decide if the title "An Early Look" is meant to be ironic, or is just a sad indicator of progress.

    Despite that, I would say that three things have recently happened demonstrating the improvement in quality of PHP:
    1. End of Life of PHP 4
    2. Many important improvments in PHP 5.3
    3. Unicode in PHP 6

  24. Re:Finally by dgatwood · · Score: 3, Informative

    PHP is much, much closer to C than C++ with truckloads of STL piled on top. Ask a C programmer to comprehend that mess and you'll likely have a suicide on your hands. It is very un-C-like. The point is that the PHP syntax for arrays is very nearly identical in behavior and syntax to C, just with lots of extra functionality (variable length associative array). I never said that C++ couldn't do those things, but as far as I've seen, when you do it in C++, you're generally way off the deep end as far as being syntactically familiar to C programmers.

    I guess what it comes down to is this: if you think templates are elegant, then we will never agree about what makes a good language design. From my perspective, templates are what happens when somebody forgets that we have a perfectly good C preprocessor and decides to reinvent the wheel with a clumsy syntax that doesn't provide anything more than what C preprocessing could already provide, wedging the concept into the language itself for no apparent reason. It is anathema. It is absolutely the antithesis of good language design.

    As for OO in PHP, I don't see why you think dynamic typing decreases the value of object-oriented programming. If you really are mostly using the same code with different underlying types, then there's little point in doing OO, but in my experience, that's the exception rather than the rule. Most of the situations where I've used OO with polymorphism, I've had polymorphism, but the underlying implementation has differed substantially, and the only thing similar was the method name (and the general concept for what the function does).

    Also, it is nice to use classes even when you don't need polymorphism. This reduces pollution of the global function namespace. It also makes it easy to create complex data structures that make life easier. (PHP doesn't have the notion of a struct, so you have to either use a class or an associative array.)

    Finally PHP is still very much a typed language. It's not like there is no notion of types and everything is polymorphic with everything. The type of a variable is determined when the variable is assigned, and some types can be coerced into other types in certain use cases, but it isn't universal. I can't do if ($arrayA < $scalarB), for example. PHP even has the notion of casting to force type conversion just like you do in C. For example:

    function myfunc($mynumber) {
    $mynumber = (int)$mynumber;
    ...
    }

    Dynamic typing doesn't mean the types aren't there. If you call a method on an object that doesn't exist on that object, it is still an error. And so on. Dynamic typing just makes it a little easier to shoot yourself in the foot by not throwing up an error when you make the assignment or function call in the first place. :-)
