I called dirty the .. in my example.

/*

echo !DOCTYPE HTML PUBLIC \-//IETF//DTD HTML 2.0//EN\;

echo pThe requested URL  . $_SERVER['REQUEST_URL'] . was not found

Note, that you must not have any output before sending header(). There

I do not consider it polluting - it is there to be used. If your code

Hm... I do not know your project, but to have many classes just to

class called subscription, which might even extend a class called 
person or user - the subscription class can have methods, for 
instance subscribe and unsubscribe, and because subscription 
extends person or user - it already knows who is the person/user.


And then, for example, to subscribe a person/user, you do -

$subscription-subscribe($list_id);

Other possible actions -

$subscription-un_subscribe($list_id);
$subscription-is_subscriber($list_id);
$subscription-lists();

etc.

This way class subscription packs the methods needed to handle 
subscription related activities, so in your own jargon, this class is 
a package.


Of course, if the subscription process is extremely complicated, you can 
have more classes.

I personally do not trust file system level locks. Even if a software is

use different file systems under the same operating system, and the 
rules might be different. Using file system level locks would require 
all possible file systems to be taken into account. And on top of that, 
the file systems are actively developed, so this is one more point to 
monitor, while maintaining the software. A less trouble free way is to 
create a file with the same name and extension .locked or similar, 
prior to read/write operations. Of course, this works only if the file 
is accessing only by one program, or if all programs accessing the file 
follow the same convention - but you should see that many file system 
level locks are advisory, as well.

[PHP] the class as a namespace

[Iv Ray]

Is there a notion of the class as a namespace?

My understanding is that the namespaces are intended to help organize 
the classes in large projects (and are not perfect).


Is it considered good style to use a class simply to box related functions?

For instance, a class called files, contains functions I need for 
dealing with files - and the instantiated object is _simply_ used to 
access these functions - the instantiated object is not a file in 
itself. Thus what I do is not $INSTANTIATED_OBJECT-save(), but 
$INSTANTIATED_OBJECT-save($file) (though I could do the first if I 
first, say, do $INSTANTIATED_OBJECT-file = $file.


Accessing the functions using the scope resolution operator (::) avoids 
the need to instantiate an object, but does not allow the use of $this, 
and $this can be quite practical in order to group common logic into 
shared methods within the class and thus make the other methods smaller 
in terms of code (of course, one could use file::save, file::delete 
instead of $this-save and $this-delete, but it makes renaming objects 
more difficult).


I would be interested to hear opinions.

Perhaps what you need is this -

Upgrading PHP with the Install

To upgrade, run the installer either graphically or from the command

remove your old installation, and reinstall PHP with the same options as 
before. It is recommended that you use this method of keeping PHP 
updated instead of manually replacing the files in the installation

Re: [PHP] Using SVN w/ Zend Studio for Eclipse

[Iv Ray]

 I do not want to copy the project into a new
 directory as the existing directory is where Apache's DocumentRoot is
 set. And although that's simple to change, I really don't think any
 IDE should mandate where I set my project's directory on the
 filesystem.

I use PDT, and there is no problem to import a project from its current 
location.


It might take you a while to exactly figure out how to do it, Eclipse is 
a bit organic in respect to the organization and working of the menus.


 Also, if I try to create a new project from an SVN
 Repository, it doesn't allow me to select what directory I want the
 code checked out in.

This works very well with PDT and Subclipse.

 Otherwise I'd just cringe and let it overwrite
 what's in my existing document root, since that's all versioned code
 anyhow.

If your current document root is a checked out svn project, 
PDT/Subclipse will see this, no need to overwrite anything.


 If any of you have run into similar frustrations, I'd love to hear it.
 So far I've spent the better part of the evening fiddling with
 extremely rudimentary features which no IDE in any programming
 environment I've ever worked with has imposed on me. Perhaps this
 thing isn't ready for mainstream yet, or perhaps I'm missing something
 obvious.

Again, I work with PDT/Subclipse.

Eclipse is simply too organic compared to what you are used to. Just

 What technique can I use to take an 8-byte double precision value, as

Does it get misinterpreted, or do you just want to be sure?

The documentation says -

Some references to the type double may remain in the manual. Consider 
double the same as float; the two names exist only for historic reasons.


Does this cover your case?

You mean you extract 40 58 FF 5C 28 F5 C2 8F, so to speak, as a 
string, right?


Sorry, for asking, but somehow I do not the case.

Re: [PHP] changing order of items

this one bugs me for a while. how to change order.

I have a list of tasks. by status, task could be 1 (todo) or 0 (done) -
status value stored in mysql. I can list tasks per status or all.
order number is stored in mysql too.
the easiest way to change order is to have form for each task where you
will enter manually number and then submit (one submit button for whole
form). but, if you change order number for any task you have to change
then all order numbers below the task manually

solution with arrows (or up/down buttons) where you click on arrow and
the task switch the place with its neighbor is easy and fancy. Though,
I get in trouble if, e.g. tasks 10, 11, 12, and 13 change status from 1
to 0 and I have to move task 14 to place 6. I have to click first 4
times (to switch places with tasks 13, 12, 11, and 10) - but nothing is
actually happening on screen (of course) before start switching places
with 9, 8, 7, and 6.

how do you avoid this gap?
what solution do you use at all?


You have two different issues - a) how to execute the change, and b) 
what interface to provide.


To execute the change, basically you have to reorder. The best algorithm 
is question of mathematics - you can implement something and improve 
it independently from the interface.


As for the interface, the first is kind of the simplest, but somehow 
primitive. The second is a bit better, but you have noticed, not much 
better. The most elegant, considering the time we live in, would be drag 
 drop AJAX (here - http://tool-man.org/examples/, there are excellent 
examples, perhaps there are more).


It's also a question if tasks really need to be reordered manually. If 
all tasks have a deadline, you might sort them by date. If some don't, 
you can provide them unsorted, until they get one. Sorting tasks by 
moving them up/down works when you have 25 tasks, but it does not work 
when you have 50, 100, 1 000 (if you are a team leader and have 5-7 
people team) - in that case sort by date might be better.


If you get more advanced, and store time needed to complete a task, you 
could automatically shift all tasks (of a person) - when one gets 
delayed or takes longer, than planned.


Hope that helps,
Iv

You have messed up the brackets. This -

strlen(trim($name) == 0 )

should be -

strlen(trim($name)) == 0

Then the script does what you want.

From usability point of view such check will, in many cases, generate 
annoyance, and bring nothing.


If I do not want to enter anything, and you error me to enter 
something, I'll do like this -


asdlöfjasdpoöfja spdfj as fsdaölkjf

And your check is dead. If you want something, you will get something.

It is hard (from usability point of view) to validate textarea to that 
extent, and especially - to get reasonable answers...


I work for a scientific database, where all content providers are very 
intelligent, well educated and very disciplined, and the content editors 
still have hard time thinking how to guide the content provider so that 
they provide reasonable input.


Your problem is not so much php related, but a usability and editorial one.

[PHP] getting iostat -x %b with php

[Iv Ray]

What is the best way to extract just the drive load information (%b 
column) from iostat -x (on  FreeBSD)?


I imagine to exec() the iostat -x and then process the result with 
regex, but I am not sure if this is the best way - for instance, is %b 
is aways the Nth column in the returned value?
