Pretty damn cool.

HipHop has been available for a very long time. However, it's for people who actually have speed problems with PHP, and are under constant load. Not for the common man. Cool though.

Hmmn, maybe i can use it later on. . . .on my 127.0.0.1
Re: Facebook Releases A Php Just-in-time Compiler by ektbear: 10:11am On Dec 13, 2011
This is a different technology from the previous release, right? The old hip-hop was PHP to C++, if I understand it correctly.

This otoh is a JIT compiler.

Yup!!
Re: Facebook Releases A Php Just-in-time Compiler by Nobody: 11:57am On Dec 18, 2011
sometimes the way i look at it the more you touch PHP the more you notice at a certain point to go advanced you need to know c++,
Re: Facebook Releases A Php Just-in-time Compiler by Nobody: 1:36pm On Dec 18, 2011
^^^Yeap that is very true. Luckily i know some basic C/C++ before i came to web programming, so i am managing to cope. . .
Re: Facebook Releases A Php Just-in-time Compiler by Nobody: 1:41pm On Dec 18, 2011
cuz i saw an article about extending people to create your own functions i know a bit of c++ till pointers the rest am still confused but little by little am getting it, cuz mehn PHP does a lot that wasn't even sure it could it can connect MSWord ,call .NET classes and Java, execute command line application from the system and return the result. i just dey trip but its no rush afterall we're in this for a long while. dhtml how we dey do christmas.
Re: Facebook Releases A Php Just-in-time Compiler by Nobody: 2:04pm On Dec 18, 2011
^^^Not sure yet. There was one small app i did with php/c++ that allows any mail you send on my localhost go into mysql database, so i have like an offline mail system for testing mail stuffs. I made it a bit like fakesendmail except that some of those apps will send mail to your mailbox and will need internet.
This one is very fast, just a few lines of c++ code.
Re: Facebook Releases A Php Just-in-time Compiler by Nobody: 2:15pm On Dec 18, 2011
^^^ thats awesome that way one can test mailing functions mehn gots to read the c++ to the levl that it will help me.
Re: Facebook Releases A Php Just-in-time Compiler by Nobody: 2:28pm On Dec 18, 2011
I will blog it. I wont even mind showing omo_to_dun the code maybe he can help improve it. I just did some patch 'em up very lousy c++ coding, but it solved the problem. But i still feel that speed should increase by a few more seconds if a professional c++ coder touch it.
I used some msdos batch file in some areas where i did not know the c++ functions to use. Then i used php to do some cover up where c++ could have done the work. I used vb6 earlier, but the performance was too poor for a commandline app, i was tempted to use vb.net but gave up - too much dependencies, i wanted something easy and straightforward.

I think i will clean up the code first before blogging it so that the setup instructions will not be too much. That way we keep it professional.

Or maybe we should sell it
Re: Facebook Releases A Php Just-in-time Compiler by ektbear: 7:21am On Dec 19, 2011
How difficult was it write an extension in C++? And how much did it improve your performance by?

What i was trying to say was that there was much hardcoding in what i did. Fine it worked, but the code is rather too rough and complicated.

Take a look at this line:

[Inside c++] - i wanted to execute the dos command below
system("/wamp/sendmail/save.bat"wink;

[save.bat] - i had some issues, so i had to put that is a batch file because i had issues running that command in c++
\wamp\bin\php\php5.2.9-2\php.exe -f \wamp\sendmail\save.php

HipHop parses PHP into C++. It is not a just in time compiler and it will never be.

HipHop for PHP is a source code transformer for PHP script code. HipHop programmatically transforms PHP source code into highly optimized C++ and then uses g++ to compile it to machine code. HipHop includes a code transformer, a reimplementation of PHP's runtime system, and a rewrite of many common PHP Extensions to take advantage of these performance optimizations.[1]

HipHop for PHP can substantially increase the speed of PHP applications. Improvements of web page generation throughput by factors of 2 to 6 have been observed.[2][3]

HipHop was created by Facebook to save resources on its servers. It is being distributed with its over 300,000 lines of source code written in C++ and C as free software under the terms of version 3.01 of the PHP License.

If you click the link in the OP, you'll see that there are two products named "HipHop." This older one, and something newer (a JIT compiler.)
