Let imagine that we have a site that gets a 1000 requests per second. That seems to be a good candidate for threading so as to be able to handle the 1000 requests per second. The site runs PHP and Apache. Well, what happens? Each request coming in is handed of to a separate instance of Apache. Thus the site would be able to process many requests simultaneously. It looks as if parallel computing is taking place here, which looks much like threading. Even though PHP itself does not know about threads, and does not need to, I think, the whole process of handling the 1000 requests per second uses parallel computing. There are no performance bottle-necks here. Teus. # of requests / second can be solved by load balancers/clusters. What about the multiple answers for a simple request per user as in my example? How you would solve that if not by threading? Amazon has about 30 million products and they have filters similar to what I mentioned. But when clicking on one of the I18n site at the bottom, you're taken to another server, which looks like it uses a different DB back end (I could be wrong) and you don't get instant translation of the category you're looking at. Their response time is about 3 seconds on my 10mbs (not cable) download. As for what programming language they use... Honestly, how WOULD you solve that with threading? You describe a page that needs to be generated that has a half-dozen queries against the database ranging from simple to moderately complex, some of which are site-generic and some are user-specific. How does one solve that with threading? 1) Run the site-generic queries once and cache them in memory and let other threads just use that query result. You can do that without threads. Just render that part of the page and cache that string to disk, to the database, or to memcache. If the memecache server is on the same box then it should be identical to the threading version, performance-wise. (Give or take VM considerations.) 2) Push the user-specific DB queries to separate threads so they can run in parallel. All that does is push the hard work off onto the DB server, which is still running the same number of queries. And PHP can't respond until all of the queries finish anyway, and the DB server will respond no faster, so you're really gaining nothing. You keep saying how would you solve this without threads? as if they're some magical speed fairy dust. Given the scenario you describe, I don't even see how threads would buy you anything at all. Where threads would be useful is for lots of very small writes on rapidly changing data. I would never want to write, say, the World of Warcraft servers without threading and a persistent runtime, but then I wouldn't want to write them in PHP to begin with. Insert that old saying about hammers and nails here. --Larry Garfield The difference is doing all those queries in serial operations (one after another) versus parallel operations (threads). Instead of waiting, for example, about .05 to .25 sec for each of those queries, the total wait time would be diminishes since each thread would execute a query. Either way, the DB is still doing the required total work. Difference is serial parallel operations as I iterated several times. Being running in parallel, the web browser will be getting the required info faster since PHP is able to get all the info faster. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well, the multiple answers for a simple request per user as in your example, seem to be a lot of information to display all on one page, and present all that information to the user in one request. I would probably resolve it, IMHO, by using pagers. That is, only part of the Pagers are needed when there's a lot of products to display. But using the filters and show them is different. Look at Amazon (not endorsing it). Click any category. You'll see what I mean by the filters (manufacturers, price range, subcategories, etc) and the display requirements (specials, bestsellers) as I mentioned. They also have other things, like shoppers' discussions, on that page too. Think about how many queries they have to run for all that info to show based on a simple request of a 'category'. Then time the response time. information is shown to the user at one time, and the user can page through that information so as to get to other bits of information. If only part is shown, then the database query becomes so much faster (hopefully), and PHP still can do all of it in one thread. A PHP application, by the nature of PHP, consists of small page requests to be done at one time, rather than move a lot of information around per request. Thinking the PHP-way requires some study because, as said, the information is presented or moved about in small chunks. Desktop applications, and probably Java web applications (I have no experience with Java but have read up on it a little) work differently. A successful PHP application is redesigned from the ground up, rather than remorphing a Java or other desktop application in PHP without changing the design principles. The key to makign your eCommerce application snappy, is, I think, not threading, but optimization of database queries. And another key is that less information presented to the user is usually clearer to the user, and thus they feel better at the site, and would return sooner to buy something. The real head-ache here and the difficult part is: How to design a clear and clean interface for the user. It's not threading.

Re: [PHP] PHP to access shell script to print barcodes
The problem you're getting is that your web-server interprets the
request as a request for a normal file and just sends it - in effect,
you're not outputting the postscript file, you're just sending the
.php file. Normally, you'll only get your php executed if the file
requested is a .php or .phtml - unless you've changed your server
config.
Try creating a serveps.php that uses the header(Content-Disposition:
attachment; filename: 'serveps.ps') instead, see if that helps you.

I run real time systems for offices that count serving time in seconds. I know currently where the bottlenecks are, and adding 'threading' to PHP is not a solution. I fact adding much of the dross that has been added to PHP5 is ACTUALLY slowing down performance. I have PHP5.3 and PHP5.2 running on similarly loaded sites, and PHP5.2 is faster! I am just pointing out that on *MY* REAL applications, the SQL element is a major part of the processing time, and yes moving some of the table lookups to be hard coded arrays in PHP would make a difference, but then complicates configurability, so keeping them in the database makes life easier. The proper design is the one that meets the customers requirements and gets the bills paid. Processing the raw statistics required for my own sites is best done away from PHP, so using the right tools for the job is the important thing? -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

exactly. the knock-on problems you mentioned are well solved and well documented. realtime programmers using threads have to get their heads around it on their first realtime project. i don't like doing my code in c(++), or worse; having to interface between c(++) and php. i chose php because my code can stay close to simple english that way. what you're suggesting is highly intrusive in my work-style, one that you're not affected by at all. in fact if you make things more difficult for me, i have less time to release opensource code of my own.

You wouldn't want to be responsible for sending the newbies down that path would you?! :p Thanks, Ash http://www.ashleysheridan.co.uk == That's not a good argument against implementing threading, regardless of the technical issues involved in making it work. There are plenty of more advanced areas of php that beginners stay clear of. Just because threading is available doesn't mean it will automatically be used or even considered in most projects. I wrote C code for years in a large fairly complex banking front-office system and only found a very few occasions where threading was required to get the job done. In the majority of C and C++ code you find very few examples of threading, either because it's not required (99.9% of the time) or the coder didn't feel comfortable using it and found another way to achieve the result. In the few occasions where I did use threading I would say that most the time there was no other way of achieving the required result. But the issues you need to solve with C are very different to the issues you need to solve with php. I've spent more than 8 years coding php and I haven't ever hit a brick wall because of the lack of threading, but of course every project is different and I'm sure there are situations out there where trying to work around the lack of threading can cause major hassles. But as others have pointed out you use the right tools for the job, and if php doesn't have what is required then use something else.

This thread has almost now turned into a platform for insulting each other. Why do those few feel it necessary to do this on what could otherwise be an intelligent discussion? There are clearly two sides for this, although it does seem that the majority of this list (or at least those that have participated in the thread) are in favour of not including threading support in PHP. Rene, clearly you feel strongly about this. Why don't you ask on the internals list, as that is where you'll get the best response about whether or not it is something that is feasible (although feasibility is no indicator of whether it will be included or not) Thanks, Ash http://www.ashleysheridan.co.uk

And if we can't then you may actually convince us that threading would be a valuable feature to have available. You mentioned Facebook as an example of a popular application. Are you aware that they only recently started using their compiler in production, and that prior to that they were happily running PHP to serve their front end without ever complaining that it didn't support threading? Even now, with hip-hop, individual requests are served in a single thread, so the language itself still doesn't support threading, and I don't hear them complaining that it's costing them a fortune. Why? Because it's not. And if it was they would have added it by now. One final thing... if threading is this important to you, then I'm sure there are a number of developers who would happily add it in a fork of the core for suitable compensation. Once implemented it's possible the internals team would accept it for addition to the official version. If you really believe it has the potential to save you a butt-load of cash, the economics of paying for it should stack up. Oh, and feel free to escalate this to anyone you please. Nobody cares.

STOP TRYING TO DETERMINE MY HABITS AND CHOICE OF TOOLS. You mentioned Facebook as an example of a popular application. Are you aware that they only recently started using their compiler in production, and that prior to that they were happily running PHP to serve their front end without ever complaining that it didn't support threading? Even now, with hip-hop, individual requests are served in a single thread, so the language itself still doesn't support threading, and I don't hear them complaining that it's costing them a fortune. Why? Because it's not. And if it was they would have added it by now. yea, they didn't complain, they had the cash income to build the hip-hop compiler. i thank 'm for it. One final thing... if threading is this important to you, then I'm sure there are a number of developers who would happily add it in a fork of the core for suitable compensation. Once implemented it's possible the internals team would accept it for addition to the official version. If you really believe it has the potential to save you a butt-load of cash, the economics of paying for it should stack up. I dont feel i need to pay for a programming language keeping up with the times. Then i'll indeed find another language to use.

Give us a real example of why you think it should be supported and I guarantee we can come up with a way to get you what you want without requiring massive changes to the core of your chosen tool. And if we can't then you may actually convince us that threading would be a valuable feature to have available. I did give a real life example, ie e-commerce site mentioned earlier. Amazon has the similar features of my example except they have about 30 million products without (i18n). Their I18n is different web server db site layout which is completely different from my example. Setting I18n aside, having the same features as my example with about 30 million products to response in about 3 seconds is very good. Even though my example only have about 750,000 products, the translations for the requested languages makes it into 750,000 * 6 = 4,500,000 rows of product descriptions. This is e-commerce site not a data warehouse/mining. What would happen then if the site has over 20,000,000 product skus with similar language translations for the descriptions? 20,000,000 * 6 = ... big number to me... How exactly will threading in PHP help with the size of the database? That makes no sense to me, please help me understand how you think threading will help in this scenario. Looking at my example, not just the rows There are other features that require queries to a DB for simple request of a category by a shopper, instead of running those queries in series, running them in parallel would yield better response time. Database size issues are tackled with clustering, caching and DB optimisation. Threading in the language accessing the DB has no advantage here. Yes, it does. As mentioned several times, instead of running the queries in series, run them in parallel. If each of the queries takes about .05 to .15 seconds. How long would it take to run them in serial? How long do you it take to run them in parallel? -Stuart -- http://stut.net/ The database is still a bottleneck. Now instead of processing one query at a time for a PHP script, it's processing 3 because you want them processed in parallel. Now the database is struggling with 3 times the work to complete in the same amount of time. Threading hasn't helped that much here, you've just moved the problem to an area which is already generally considered the bottleneck in most applications. Thanks, Ash http://www.ashleysheridan.co.uk Take your current project. Look at the page where the most queries are executed. Time how long it would take to run each of those queries in your SQL GUI Tool. Add the numbers together. Now think how long it would take to run those same queries under the same conditions in parallel. ... :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I completely agree, but I wouldn't go near PHP for a realtime system in a million years.

I'm not trying to tell you what to use, I'm simply pointing out that you appear to be fixed on PHP for some reason and I don't understand why. It makes no sense to me, but frankly I don't care. You mentioned Facebook as an example of a popular application. Are you aware that they only recently started using their compiler in production, and that prior to that they were happily running PHP to serve their front end without ever complaining that it didn't support threading? Even now, with hip-hop, individual requests are served in a single thread, so the language itself still doesn't support threading, and I don't hear them complaining that it's costing them a fortune. Why? Because it's not. And if it was they would have added it by now. yea, they didn't complain, they had the cash income to build the hip-hop compiler. i thank 'm for it. Way to skip over my point. Facebook is pretty much guaranteed to be a bigger site in terms of data size and concurrent users than anything you or I are ever going to be involved in, and yet they don't think threading in PHP is important. That was my point. One final thing... if threading is this important to you, then I'm sure there are a number of developers who would happily add it in a fork of the core for suitable compensation. Once implemented it's possible the internals team would accept it for addition to the official version. If you really believe it has the potential to save you a butt-load of cash, the economics of paying for it should stack up. I dont feel i need to pay for a programming language keeping up with the times. Then i'll indeed find another language to use. I find it curious and amusing that you think the lack of threading support means PHP is somehow living in the dark ages.

Re: [PHP] Will PHP ever grow up and have threading?
again; i have neither the expertise ready, nor the time nor the money atm, to implement it myself. i'm hoping the php-dev team will agree with me that scalability of php driven apps should be put on the agenda. threading and shared memory are only a part of that discussion.. i'm opening a new thread to discuss this wider issue.

If you believe you have the chance of becoming as big as Facebook and that you would save loads of money by having PHP support multi-threading, what's preventing you from hiring people to add that to PHP? You can complain all you want, but even with the most compelling reasons in the world it will not be done if there is not enough manpower to do it. I'm not even sure why you are complaining about this on the general list. Why don't you write an RFC and send it to internals for discussion? I'm sure someone would be happy to give you write access to the rfc namespace on the wiki if you sign up for an account there. Seeing as it's apparently so crucial to the operation of your business, I don't think it's unreasonable that you commit some resources to it. I don't think anyone is *against* that PHP supports multi-threading. I think people are against having multi-threading if it will stall other development in the PHP core. It's not like you can implement it just like that.

Database size issues are tackled with clustering, caching and DB optimisation. Threading in the language accessing the DB has no advantage here. Yes, it does.

I just have a huge problem understanding why alternative solutions to problems are thrown out with No! That won't work when they haven't been shown to be problematic. So far, we've seen no examples of situations where PHP would be the best choice of language and would need threads to solve the problem at hand.

All these methods eventually call the real class with the complex

Don't give specify any parameters in the function declaration.
Use helper functions inside the class, and decide at the constructor
which helper to call using func_get_arg() and func_get_args()
You can get the no. of arguments using count(func_get_args())
and then using swtich statement call the relevant helper function using
call_user_func_array with parameters.
A sample:
public function __construct() {
switch(count(func_get_args())) {
case 1:
call_user_func_array(array($this, '_helper1'), func_get_args());
break;
// and so on
}

[PHP] Recommended Books on Object Oriented Programming
Hi, I want to properly learn object oriented programming as I've been coding in procedural style since I started with PHP a few years ago, and want to give OOP a shot. The web isn't really a good resource to learn OOP in PHP to be honest, as a lot is outdated for PHP4's style of OOP. I've looked into OOP quite a bit and understand the concept of it, and want to take it further. Any recommendations appreciated :). Thanks, Ben.

I'm not building different types of pizza. Just the same pizza via
different routes.
Along the lines of ...
Pizza = new Pizza('MyFavouritePizza') // A ham+pineapple+cheese pizza.
Pizza = new Pizza('ham', 'pineapple', 'cheese'); // A generic
ham+pineapple+cheese pizza
Pizza = new Pizza(array('base' = 'thin', 'toppings' = array('ham',
'pineapple'), 'cheese'=true)); // A complex description.
I suppose the interfaces are beginner, intermediate and advanced, but
ultimately all generate identical objects.

Re: [PHP] Properly handling multiple constructors.
And how exactly does that differ from building the same pizza in
different ways? Builder doesn't mean you have to create different
objects, it means taking the complexity in building a given object or
set of objects and storing it in one place.
In your case, it allows you to build your object in different ways
while documenting it properly and avoid the huge switch inside your
constructor that Nilesh proposed.

Each constructor will end up with all the parts being known ($Key,
$Part1, $Part2, $Part3, $Complex).
But, PHP doesn't support multiple constructors.
Initially I thought about this ...
__construct($Key_Part1_Complex, $Part2=Null, $Part3=Null)
But then documenting the first param as being 1 of three different

So I'm looking for a clean and easily understood way to provide this.
I won't be the only user of the code and not everyone has the same

I think I may need a factory with multiple methods (FactoryKey,
FactoryPart1To3, FactoryComplex). Make the factory a static/singleton.
All these methods eventually call the real class with the complex
rule.
Is that obvious enough?

I'm not building different types of pizza. Just the same pizza via
different routes.
Along the lines of ...
Pizza = new Pizza('MyFavouritePizza') // A ham+pineapple+cheese pizza.
Pizza = new Pizza('ham', 'pineapple', 'cheese'); // A generic
ham+pineapple+cheese pizza
Pizza = new Pizza(array('base' = 'thin', 'toppings' = array('ham',
'pineapple'), 'cheese'=true)); // A complex description.
I suppose the interfaces are beginner, intermediate and advanced, but
ultimately all generate identical objects.

Re: [PHP] how to do cloud computing with php
On 24 Mar 2010, at 11:55, Rene Veerman wrote: As a way to take a few steps back from the kinda heated when will php grow up and support threading thread, i'm requesting you people list how you scale from 1 server to many servers; what's called cloud computing. In particular, i'm interested in how to set up an application that deals with great amounts of input from many 3rd-party servers, and say a million concurrent viewers who need html calculated from those input streams. So this goes beyond 1 mysql server, and beyond 1 php server. Let's hear it, coz quite frankly i have my doubts about php's ability to scale to cloud computing. The way you're using the term cloud computing differs from the generally accepted definition, which is delivering hosted services over the Internet. What you're talking about is scaling an application beyond a single server which is a different, albeit usually related, beast. There is no single or right way to implement a scalable web application but there are some key principles. The main principle that enables maintainable scalable systems is layers. If you build your application in a layered fashion, such that no layer knows how the other layers work, you can modify any of the layers in any way you need to when scalability issues arise. Your hardware setup will depend on the application and usage patterns, but some combination of load balancers, application servers and database servers is pretty normal. You may also find servers dedicated to caching and offline processing useful to achieve your goals. Architecture-wise you'll want to make extensive use of caching to lighten the load on the database, and you'll want to make sure that you perform no processing during a request that could wait to be processed offline. The main site I maintain has two load balancers at the front running nginx, three application servers running FastCGI PHP processes, two database servers in a master/slave arrangement, a separate static server and two offline processing servers. The application servers all have memcached instances for caching purposes and each runs its own instance of Sphinx to localise the search load. That setup, combined with a shared-nothing approach to the application design means I have a highly scalable system. To add capacity I simple need to add servers in whichever group is having issues. Due to the nature of the application I'm yet to come close to having issues with the number of concurrent writes to the database, but when I do I already plan to add another master server such that I have a master/master/slave setup. Unless you do start getting the sort of traffic that Facebook are blessed with you will be able to get a long way with this type of arrangement. And with a modular, layered approach to the application design I don't see any reason why I can't handle any scalability issue that's likely to come along with a minimum of fuss and cost. The key think to remember is that scalability is not the same as performance. They're barely even related. What, specifically, makes you doubt PHP's ability to scale? -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

And how exactly does that differ from building the same pizza in
different ways? Builder doesn't mean you have to create different
objects, it means taking the complexity in building a given object or
set of objects and storing it in one place.
In your case, it allows you to build your object in different ways
while documenting it properly and avoid the huge switch inside your
constructor that Nilesh proposed.

Hi.
I have a scenario where I would _like_ to have multiple constructors

Each constructor has a greater number of parameters than the previous one.
e.g.
?php
class myClass {
__construct(string $Key) // use key to get the complex details.
__construct(string $Part1, string $Part2, string $Part3) //
Alternative route to the complex details.
__construct(array $Complex) // All the details

Per Jessen wrote: Rene Veerman wrote: stop bashing the people who DO have a use for threading and other advanced concepts eh. I'm not bashing anyone. just because you don't have a use for it, it shouldn't be included?! kinda arrogant. Feel free to think so - I never said I don't have a use for it (threading), I just said thread-support doesn't belong in PHP. This is a more interesting statement since this thread started with douche-bag. I disagree with your assertion that it doesn't belong in PHP, I think threading has its merits, but the kinds of problems thrown at this thread so far don't seem particularly solved by threading. 500 requests each with 10 threads hitting the database is 5000 queries. Threading isn't going to make a whole hell of a lot of difference versus 10 serial queries sent by the same 500 web server requests-- multi core system or otherwise. Facebook and other popular sites get along well with PHP. Note that Facebook created a compiler for PHP, they didn't add support for threading. This suggests that threading is not the golden hammer being sought in this thread. However, threading certainly would be great for doing more desktoppy stuff :) Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] constants STDOUT, STDERR, STDIN not working in 5.2.x?
Hello, dan...@daniel-laptop:~$ php test.php /dev/null Error 1 Error 2 dan...@daniel-laptop:~$ ./src/php-5.2.12/sapi/cli/php test.php /dev/null Error 1 Error 2 well, using php-cli instead of php-cgi, this finally worked: ? fwrite(STDERR, test\n); fclose(STDERR); ? But why doesn't it work with php-cgi? That's a binary that is called with the php-file is parameter the same way as php-cli. So both come with STDIN/STDOUT/STDERR contrary to scripts running through mod_php. What is the real difference between php-cli and php-cgi? This fclose(STDERR); is really important for one customer, because this is seems to be the only way to suppress later output to STDERR in the same script by external commands and functions that are too hard to change. But I don't want to break things for all other customers just to make one happier. Can the STDERR constands be enable somehow at compile-time for php-cgi?

Scaling PHP I quote As PHP has gained more acceptance as a serious language, there's still been a significant camp of people claiming that it can't scale. Clearly, this isn't the case. page 212.
