FWIW Yahoo! runs on PHP (including properties such as flickr and del.icio.us). To be precise, PHP 5 using the Symfony framework.

So PHP, used effectively, is capable of handling around 3.5 billion page views per day from around the world, with appropriate horizontal scaling.

Relational databases at Y! are either mySQL or Oracle.

Of course they have some requirements for scaling capacity and responsiveness that no relational database now extant could ever cope with, which are met by custom distributed file systems - a bit like the way Google uses the proprietary BigTable architecture for its various indices. I believe the low-level drivers for such things are written in C. But you only need to worry about that kind of stuff when you have hundreds of millions of users

Good injection of facts there, me old bonobo.

It amuses me that things like .NET are used for comparatively small applications (web-wise) whereas 'noddy' technologies like PHP and MySQL drive some of the biggest applications ever seen.

newbie-rookie,

are you a cat too ?

Milan.

I have no idea what cat is sorry.

I have to admit folks, part of the reason I made the move from developer to administrator was I never understood object orientation, especially this kind of stuff...

$salary->Paycut

and then the like..

this->paycut


funny eh

Thankfully I didn't understand cos if I had I'd probably still be stuck there as a developer taking all the cripe

one of the worst things about being a developer is when during unit testing the business realises they got the spec wrong and expect the new spec to be delivered in the old time scale to the original deadline

those were the days

Milan.

You would use $this->Paycut() from within the class.

When using an instance of the class, you would use $instance->Paycut();

Not terribly hard to grasp, really.

I'm not a developer now, either. But I like to keep in touch rather than sneering at those who do.

i did some hacking with php3 and it was funny then that there is no distinction between, ints, chars, date etc

is it still the case today ?

Milan.

Yes it's loosly-typed but you can cast types:

$mySalary = (float) $notEnough;

Also you can 'hint' types for arguments:

public function MilansSalary(AbsurdlyOverPaidClass $salary)
{
return $salary->Paycut(100);
}

You can use type hints in method parameters and variable assignments now.

I found the tool support to be pretty poor, that was the biggest draw back for me. Stuff like auto complete was not there when I was working on it. Might have changed though. I could knock stuff up pretty quickly but I always though i was just coding hacks and nothing was stopping me.

Oh, it has. Now you can use phpdoc (something like javadoc) and you can use autocomplete in your ide (I use Zend Studio and PHPed). Also I find Browser toolbars which allows you to debug your code line by line very helpful.

You can use Visual Studio for PHP: http://www.jcxsoftware.com/vs.php

I'd agree if we were talking about PHP before OO. Now, you can build serious applications with PHP using MVC, OO, ActiveRecord etc. Especially with frameworks like Zend, Symphony, I feel like PHP becoming more like a programming language than scripting language. That's my humble opinion of course.

LOL

you sure he wasn't over qualified ?

Milan.

He has rather large paws and often hits two or three keys at once while coding.

His concepts are pretty sound, however.

Will someone please get the PHP developer role in the Midlands please. I am fed up with the dam role poping up when I am searching Jobserve. It's been there daily for about 2 weeks now.

I sent my cat for it. He got the job.
