I'm honestly having a difficult time thinking of any way *other* than
having an array of User objects. In previous projects I've tried the
route of (like Richard mentioned early on):
class Customers {
var $ids = array();
var $names = array();
}
But found it very cumbersome and unintuitive when dealing with a
single Customer. Moreso I got lost when I didn't know if I were
dealing with one or many customers...
As soon as I went to a Customer and CustomerCollection approach, I was
able to make sense of it all. Even though CustomerCollection usually
didn't actually exist, except conceptually as an array of Customer
objects within my application code. Like Stut suggested, I too have
static fetch functions derived from the base ActiveRecord class that
return arrays of objects.
Maybe all of my applications have been simple enough in that I
tended to work on single objects 95% of the time, and therefore
creating interfaces for those single objects made sense. I think
that's what Ed means by situational?
It is occuring to me that perhaps all of my bias is centered around
the fact that I always create my models as children of an ActiveRecord
class, which is by nature based on *one record* of a table.
Is there an ActiveTable class that, if implemented, might completely
change everything???
Until then, I'm not convinced: constructing a basic building block
such as a Customer, and then an aggregate block such as a collection
of Customers, and so on, seems the most stable and scalable approach
almost without exception...and perhaps, with that, I'm revealing the
extent of my OOP naivety...

Hi Deckard,
You've said that the file that is trying to perform the include is

*that* file is probably included from another file, likely located
elsewhere...
Rather than including via a relative '../' path, try an absolute path.
You can hard-code it at first
(include_once('/var/www/html/config.inc.php');), but then if it works
switch to a method like so:
[code]
// Consider *where* you create this
// Define it as a constant if you'd like...
define('BASE_PATH', dirname(__FILE__));
// Now build the path, like (assuming it was created

Re: [PHP] Re: OOP Hello World
Are you sure you're not on a Spanish *Java* mailing list?
:)
On 10/5/06, Martin Alterisio [EMAIL PROTECTED] wrote:
Me... again, still boring you to death with meaningless OOP rantings.
First I would like to point out that there was a design mistake in what I
proposed in the last mail (following afterwards): the Saluter shouldn't be
an abstract class, it isn't correct to base your class hierarchy on the
ability to greet (or in the ability to do something generally speaking). If
it's done that way we'll have classes coexisting in the same branch of the
class tree, but possibly having completely different nature. Saluter should
be an interface:
interface class Saluter {
public function greet(Salutable $receiver);
}
class FormalSaluter implements Saluter {
public function greet(Salutable $receiver) {
echo Hello . $receiver-getSalutationName() . \n;
}
}
Then, I'll try to translate what has been said in the spanish list.
It has been proposed that World should be a singleton, since there is only
one world... but this arguable, at metaphysic level perhaps...
Also an observer pattern could be used so anyone can hear the greetings. But
I think this should be done on the design of the greeting enviroment
abstraction (to provide other places than standard output where the greeting
can be said).
The saluters factory should use a factory method pattern or an abstract
factory pattern? I think an abstract factory is not appropiate in this case,
the creation process is not that complex to require this kind of design
pattern.
Also I proposed that decorators could be used to add styles to the greeting
for outputs that allow styling (e.g.:html). In this case maybe an abstract
factory would be appropiate, so that decorated saluters are created for the
appropiate type of output, combined with a builder pattern to create the
decorated saluters (this last part I thought it just now, I'll post it later
on the spanish list)
Well, I think that sums it all up.
2006/9/29, Martin Alterisio [EMAIL PROTECTED]:
What's up folks?
I just wanted to tell you about a thread that's going on in the spanish
php mailing list. A fellow software developer which had just started with
OOP was asking for Hello World examples using OOP. The examples of code he
had been doing was not that different from the usual Hello World example we
all know and love(?), so I thought he was missing the point of what was the
purpose of using OOP. This was my reply (I'll try to keep the translation as
accurate as possible):
I believe you have misunderstood what is the purpose of OOP, your objects
are not proper abstractions.
First and most important, you should define what is the problem to solve:
greet the world.
We build an abstraction of the problem and its main components: somebody
who greets and something to greet.
Here we're working with generalizations, since our main objective is to
build reusable objects. For that purpose is useful that our saluter could
be used to greet more than just the world.
Therefore we'll first define what kind of interaction we expect the
salutation receivers to have, in the following interface:
interface Salutable {
public function getSalutationName();
}
In this interface we have all we need to properly greet any entity: the
name we should use when doing the salutation.
Then we create the object which represents the world:
class World implements Salutable {
public function getSalutationName() {
return World;
}
}
Now we're missing a saluter, but we're not sure which way of greeting
would be appropiate, so we prefer to create an abstract saluter and leave
the child implementation to decide the appropiate greeting:
abstract class Saluter {
abstract public function greet(Salutable $receiver);
}
In our case we need a formal saluter as we should not disrespect the world
(saying hey! wazzup world? could be offensive), then:
class FormalSaluter extends Saluter {
public function greet(Salutable $receiver) {
echo Hello . $receiver-getSalutationName() . \n;
}
}
Finally we make our saluter greet the world:
$saluter = new FormalSaluter();
$world = new World();
$saluter-greet($world);
Other things you should keep in mind:
* PHP's type hinting is preety limited, in this case we would like to
indicate that the name should be provided as a string but we can't. Maybe it
would be useful to use an object as a wrapper for native strings. EDIT: I
remembered while translating this that type hinting can only be used in
function parameters, therefore this point is useless.
* En this model it seems more appropiate that the saluter is an abstract
class, since salutation works one way, but, in the event salutations became
a two way trip, an interface would be more appropiate for the saluters.
* Here we're sending the salutation to the standard output, which is
acceptable in this

Well I'm not going to argue with you that there is plenty of crap code
out there. PHP or not. OOP or not.
And I'm all for taking OOP in PHP seriously, but I also think it's
worth keeping in mind that the real power in PHP is not it's object
oriented capabilities, but rather its simplicity and flexibility.
And, well, I don't know if your Hello, World example keeps that in
mind.
I know that plenty of people on this list want to have a serious
conversation about OOP for PHP (should we just start using OOPHP as
the new acronym? or maybe POOPH? Or... PHOOP?!? Wait, that's not
taking thing seriously...), but I don't think a complex Hello, World
made of Saluters, Salutables, factories and abstractions is taking it
serious. I think it's exhausting the theory and using various design
patterns for the sake of using design patterns...
But really all of this comes down to the imutable truth about
programming in PHP: there are a *million* ways to skin a cat. When
you heard OOP + Hello, World, you thought about people/things
greeting each other. When I heard it, I thought about an application
outputing a string. The guy who started that particular thread
probably thought of something totally different. Who's to say who is
right?
Hey, take my words as mine alone though. Maybe I was the only one

if($myField == 'on') $myField = 1;
if(is_null($myField) $myField = 0;

The problem I am having is that the code is now on a more secure
server with register_globals off (and I don't want to turn that on).
I am not sure how to get the POST data sorted out using this method.
Hope it is clear what I mean.
Then if you need to explicitly reference the variable name within
POST, just change that line:
for ($j = 0; $j count($fields); $j++) {
$myField = $_POST[$fields[$j]];
if($myField == 'on') $myField = 1;
if(is_null($myField) $myField = 0;
$data[$fields[$j]] = $myField;

Untested. Does that work for you?

Hi Everybody, Despite all of my Googling and noodling, I can't seem to figure this out, and am hoping someone might be able to point me in the right direction. Scenario: - Running Apache 1.3 on OSX 10.4, PHP 5.1.4, MySQL 5.0.19 - Greek text is stored in a MySQL database, encoding set to UTF-8 - From within a db admin like CocoaMySQL, the greek text looks normal - PHP queries the db table for the greek text - no matter how I echo the text to screen (see below), it only produces '?' marks What I've tried: - force utf-8 headers to be sent --- header(Content-type: text/html; charset=UTF-8); - indicate utf-8 in the meta tag -- meta http-equiv=Content-Type content=text/html; charset=utf-8 / - simpley echo the string as is -- echo $greek_string; - wrap output in htmlentities() -- echo htmlentities($greek_string, ENT_NOQUOTES, 'UTF-8'); - wrap output in utf8_decode() -- echo utf8_decode($greek_string); - If I copy and paste greek characters from the db table into a string in my PHP script, and output that, it works just FINE, without any htmlentities() or other functions.

based on your checks, it will work:
[php]
$first_array = array(
'first',
'second',
'third',
'',
'',
'');
foreach ($first_array as $value)
{
if (!empty($value))$second_array[] = $value;
}
var_dump($second_array);
foreach ($first_array as $value)
{

[PHP] Re: different value in array
Nice tip Paul.
Weetat, I'm a bit concerned about your data as I look at it, and think
the approach I mentioned before needs a rewrite:
Do you have a a primary key in your arrays/rows? Meaning, how can
you tell if the two arrays you're comparing are just plain
_different_, or simply out of synch? Is it your card_serial_no? or
card_model? Or another column (like 'id') that you're not passing?
The point is, you need to know which is your primary key column and
do your testing based on these.
Then I think your whole update/new/delete/skip process might require
two passes: One to handle the update/skip assignments, and another for
the new/delete assignments. Use a combo of array_intersect() and
array_diff() to help you figure out what needs what...

Hi Angelo,
So the first question the list will ask is if the array of data is

sorting from within your database query.
Barring that, you can use the usort() function to create custom
sorting. What I've done below should do what you want, and I've tried
to generalize the functions a bit, so that you can mix descending and
ascending as you wish:
[code]
// Basic function for comparing arrays based on a particular column
function compareColumn($x, $y, $idx, $lessThan, $greaterThan)
{
if ( $x[$idx] == $y[$idx] )
return 0;
else if ( $x[$idx] $y[$idx] )
return $lessThan;
else
return $greaterThan;
}
// Calls compareColumn so that it sorts in descending order
function compareColumnDesc($x, $y, $idx)
{
return compareColumn($x, $y, $idx, 1, -1);
}
// Calls compareColumn so that it sorts in ascending order
function compareColumnAsc($x, $y, $idx)
{
return compareColumn($x, $y, $idx, -1, 1);
}
// Your customer comparison function. The order in which you call each
// compareColumn*() is the ultimate order in which your multi-dim
array is sorted.
function compare($x, $y)
{
// total is index 2 of the array
$total = compareColumnDesc($x, $y, 2);
if($total != 0) return $total;
// totalPaid is index 3 of the array
$totalPaid = compareColumnDesc($x, $y, 3);
if($totalPaid != 0) return $totalPaid;
// totalUnpaid is index 4 of the array
$totalUnpaid = compareColumnDesc($x, $y, 4);
if($totalUnpaid != 0) return $totalUnpaid;
// arrays were equal
return 0;
}
$record = array(
array(1, 'marc', 12, 5, 7),
array(5, 'berty', 30, 12, 18),
array(7, 'sarah', 19, 12, 7)

// sort your array

Re: [PHP] design?
On 6/30/06, Sjef [EMAIL PROTECTED] wrote: Thanks, John, I'm not sure I completely get the idea of a pair class. As an question and answer are in the same database tabel I now created a questionDepot class that gets the array from the db, does save and update operations, and for example, sets a flag in the db tabel when a question is accepted for the list. Hi Sjef, It sounds as if you've got the idea, even if I didn't explain myself well. My point was to *not* create a Question class that maintained an array of questions, which was only _implicitly_ related to a similarly-structured but disparate Answers class. An array of questions sitting beside an array of answers is, in my opinion, not a proper abstraction of the objects you're dealing with. Perhaps it is out of experience that I'm harping on this point, because I've been burned by a similar design before. One of my first OO projects was a weblog, and I had built a Post class, and then for posts with galleries, a separate Gallery class that contained *only* image information for it's parent Post. On it's own, this wasn't all bad, but the big mistake I made was how I handled multiple posts and multiple galleries (like for building out the homepage where I showed 5 recent posts and a thumbnail from each, if they were galleries). Within each Post and Gallery class, I turned the properties into _arrays_. So what originally was a string for the post's title, now became an array of strings for many posts. Likewise for the Gallery class. Arrays of thumbnails became arrays of arrays of thumbnails. I'm sure The List will shudder at this design, but hey, I've learned my lesson. Be-lieve-me. Anyway, the point is, your initial approach was the same (if I read it correctly). You suggested an array of questions, and an array of answers, which would only be implicitly related. Your design started with the concept of many questions, and many answers, but my argument is that, abstractly, you should begin with one question, and one answer. Then think in terms of a question-answer pair that *belong to each other*. And then think of many question-answer pairs. Anyway, I'm sure that by the time you've finished reading this hair-splitting rambling, you've already finished your app and moved on to something else entirely. :) -John W -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you're looking to do this quick and easy, it might not be worth your time fussing with OO. Unless you'd like to just for the exercise, which I wholly support, so go for it! I want to create a class Question for dealing wiht the questions and a class answer for the answers. Each could contain an array with the their part of the content of the database table. As far as how to design it OO-style, I'd first urge you *not* to have separate classes managing lists of questions and answers. Say for example you query your db for questions, build up your array inside your questions class, and then while doing the same for your answers class, you inadvertently introduce a looping bug that drops one of the answers from the array, or possibly changes the order that you create your array, or any other number of possible mistakes (human or otherwise). Point is, in the end you'd have two out-of-synch classes that really should've been built separately to begin with. A single question and it's answer(s) are tied together, so keep it that way in your class abstraction. That said, I'd suggest building a question-answer *pair* as a class, and then you'd have an array of these question-answer pairs representing your entire list (which could be encapsulated into a container class if you wished). You could, to be even more abstract, create base question and answer classes to represent the most basic type of question or answer, and then hold individual, **related** instances of these within your question-answer pair class. Do you see the difference? You could even take it a step further and build derivatives of your base answer class to represent different types (string, multiple choice with one answer, multiple choice with many answers, etc)...But I'm sure I'm already getting far ahead of your original design.

Ok Ryan, so when I first read your needs, I thought to myself web service (along the lines of Jochem's XML feed concept). But with my limited experience with it, I'm hoping others can offer some reaction to the idea. So, if you consider SOAP as your web service solution: a) Using XML eliviates your need to come up with custom serializing that is careful to not use delimiters that might also be found in your data. b) If your client and server machines are running on different languages (PHP on one, Java on the other, for example), then a WSDL file will describe the structure of your data, so your PHP array seamlessly becomes a Java array. No interoperability issues. c) You may find that after you develop this solution once, you can easily reuse it elsewhere. d) SOAP et al also includes a lot of custom error handling, so you could concievably make your solution a lot more robust. e) The standard also includes an authentication mechanism. Ok, so that's what I'm thinking. I know there's more work involved in a SOAP solution than a down-and-dirty serialize-and-stream solution, but down the road it might serve you better.

So then it would make perfect sense as a programmer to want the ability to call an object constant or static property without having to say hey, look for in the same place that I am right now. Because there's nowhere else you'd be, anyway. But with PHP, every script starts out procedurally, and hence at the global level. Then we instantiate a class, step into that object, and do our thing.

No, and the answer is actually in your example. Copy-and-paste all of
your example code into one file, and just change the second class A to
B so that there isn't a class conflict. Then create an instance of A,
and B, and call both test() methods. You'll get the following result:
111
Why? The reason is SCOPE.
A::test() echos twice, the first for the class constant MY_CONSTANT,
and the second echo's the *global* MY_CONSTANT. Then B::test() echos
the *global* MY_CONSTANT again.
As wonderful as PHP is, it can't read your mind. So if you're looking
for a constant or variable, PHP needs to know where to look. If you
don't specify self::', PHP will look in the global scope, as it did
in your code example. If you want it to look within your classes, you
need to *tell* it so.
And is self:: really a lot of boiler-plate? Really??
John W
class A {
const MY_CONSTANT = true;
public function test() {
echo self :: MY_CONSTANT; // works
echo MY_CONSTANT; // doesn't work
}
}
I don't think it is possible, but why not? Can zend/php make it work?
Seems it could since this works:
define('MY_CONSTANT', true);
class A {
public function test() {
echo MY_CONSTANT; // works
}
}
It's just annoying my how much boiler-plate I have to write all the time.

I'm willing to say that those two techniques will make you sleep much sounder at night then just stuffing thousands of lines of code through some regex checker. Oh, plus some solid QA testing.

Re: [PHP] Echo a value from an arrays position
On 5/4/06, Brad Bonkoski [EMAIL PROTECTED] wrote:
Will this also work with an associative array? If this is what he is
talking about, I tried it and it does not work
I think you're correct. This is because PHP arrays are a mash-up
(as Jochem put it) of numerical indexes/hashtables/assoc.
arrays/etc
Example:
[php]
$jonas = array('color' = 'blue', 'number' = 'three');
echo $jonas[1]; // prints nothing
$jonas = array('color' = 'blue', 'number' = 'three', 1 = 'readme');
echo $jonas[1]; // prints 'readme', even though it's technically
the third element
[/php]
So, your solution might be to first pull all of the array values out
into a new array, like this:
[php]
$jonas = array('color' = 'blue', 'number' = 'three', 1 = 'readme');
$jonas_new = array_values($jonas);
echo $jonas_new[1]; // prints 'three', as you'd hoped
[/php]
p.s. Bonus: If you wanted to get the keys out, use array_keys()
And yes, as Jay said, RTFM. It's very very helpful.

Personally, I get tired (and confused) when having to escape all of
those quotes like in the string you're trying to echo above. Perhaps
you'd consider HEREDOC as an alternative approach:
[php]
echoHEREDOC
TD WIDTH=25% ALIGN=CENTER A

Ah, Lasso! I coded that in my previous job. Left it to commit to the
world of PHP, but I saw lots of potential in Lasso 8 (we were in
3/4/5). Sort of miss it sometimes...*sniff*
Anyway, all of the comments are in the right direction. A couple
things to fill in the gaps:
PHP Arrays are indeed a mash-up like Jochem said. If you want to
get at an array element using a numerical key, then simply use the
number without any quotes, like so:
echo $array[2];
However if you want to get at an array element using a string key,
then it must be surrounded in quotes (single or double, but see below
for more):
echo $array['my_key'];
Now, single quotes and double quotes are slightly (and also very)
different in PHP. Read the manual for the details
(http://uk.php.net/manual/en/language.types.string.php), but one thing
to know is that the $ sign is a literal $ sign when it is in a string
surrounded by single quotes; but surround it with double quotes, and
it will help you create a variable (assuming you follow it with legal
variable naming characters).
So if you have a variable:
$lang = 'Lasso';
And try to print it in a string with single quotes, it won't work:
echo 'I used to program in $lang'; // this prints 'I used to program in $lang'
But around double quotes, all is well:
echo I used to program in $lang; // this prints 'I used to program in Lasso'
And if you have a complex variable within a string and you want to
help PHP figure out what's a variable and what's not, use { } to
frame the variable name:
echo Look at my class {$my_class-get('name')} and my array
{$my_array['key']} !;
Make sense? The manual explains a lot more, so be sure to read up.
Also, unless Lasso changed in 8+, there's one other thing to remember
about arrays. In PHP, arrays will keep their order of elements as you
have created it. IIRC, Lasso never guaranteed this, so you always had
to take extra measure to build your arrays such that you could iterate
through them in a reliable fashion. No worries in PHP, the order
sticks (and you can of course re-order it).
HTH, Good luck,
John W

Re: [PHP] how should MS Access DATETIME be handled in PHP?

It looks like you're building your array just fine. Here though, your

[code]
foreach ($arr as $project)
{
echo $projectbr;

Your temprorary $arr variable contains only your array of titles, not

Re: [PHP] Is it a bug of CakePHP?

Error message: Undefined index: start_date in c:\Inetpub\wwwroot\Cake\app\controllers\dsptrainings_controller.php on line 33 PHP is telling you that what you are trying to access doesn't exist. This is is a matter of you trying to access something that doesn't exist. So the question is, what does $data look like? My suggestion is to print_r($data) to see. Perhaps findBySql() doesn't return the results as an associative array? Or since you're sending a query for only one record, it doesn't send a 2-dimensional array back? Maybe your start date can be accessed simply by $data['start_date']? I don't know, I don't use CakePHP. Again, print your $data variable to the screen to find out what it contains. Consider this to be a powerful tool in your bag of debugging tricks. I print variables to the screen all the time to find out what's wrong. In fact, I'll do it in a two step process: print_r($my_variable); die(hrfilename.php:line_num); The first line prints the variable I'm after to the screen. The second line kills the script, but outputs the text I send it first. So it draws a horizontal rule across the page, and then prints out the file name and line number that the script was killed at. So if I'm tracing a particularly elusive bug, I can place these two lines in various places across my app, and walk through it step by step.

use curly brackets to help PHP understand what you're after:

[PHP] Failing to write to a file when a class is being implicitly destroyed
I hope I can explain my problem/questions clearly. Thanks in advance:
Scenario:
I'm working on a Log class that my app will use to write
debug/error/etc messages to a file. I've created it so that as the
application logs messages, these messages are queued within a property
of the Log class, and only written to the file when the Log object is
being destroyed.
I wanted to place all of the file writing to within __destruct() to
avoid holding a connection to the log file throughout the life of the
app's state.
Problem:
Everything works fine, UNLESS I move the fopen('log-file-name') call
to within the __destruct() method. If I open a handle to the log file
within the __construct() method, or any other class method, it works
fine. But I receive a permissions error if it's called within
__destruct().
Error reads: Warning: fopen(20060331.txt) [function.fopen]: failed to
open stream: Permission denied in ...
Caveat:
I have found that if I explicitly destroy an instance of Log with
unset(), then fopen() will work even when it is within the
__destruct() method. However I don't like that solution...and
besides, I'm planning on creating an instance of the Log class from
within the __construct() of my Controller class, and trying to
explicitly destroy Log with an implicit __destruct() of my Controller
doesn't work either. :P
Question(s):
1. Could anyone explain a bit more as to why fopen() won't work within
an implicit call to __destruct()? What permissions has my app lost at
this point?
2. Am I at least correct in my intention to limit the duration that
the handle to the log file is open?
3. Is there workaround to this little conundrum that anyone can think of?
Code:
Here's a simplified version of the code (it's complete, feel free to
copy-and-paste-and-play). I've commented the fopen code block in
question.
[code]
// Create an instance of Log
$log = new Log();
// Attempt to log a message
Log::debug(Here is a debug message.);
class Log
{
protected static $handle;
protected static $location;
protected static $message;
public function __construct()
{
self::$location = date(Ymd)..txt;
/* Begin fopen() */
/* When placed here, it works */
if (!self::$handle = fopen(self::$location,a))
{
echo Error. Please check permissions.;
die;
}
/* End fopen() */
}
public static function debug($message)
{
$timestamp = date(Y-m-d H:i:s T);
self::$message .= $timestamp.\tdebug\t.$message.\n;
}
public function __destruct()
{
if(self::$message)
{
/* Begin fopen() */
/* If it's here, it won't work!
if (!self::$handle = fopen(self::$location,a))
{
echo There was an error attempting to
open the log file. Please
check permissions.;
die;
}
/* End fopen() */
if (fwrite(self::$handle, self::$message) ===
FALSE)
{
echo Cannot write to file
({$this-location});
exit;
}
@fclose(self::$handle);

If it's not wrong for me to push the back button, why are you

I was a bit short in my explanation -- I tend to use the redirect
method so that users *can* use the back button (or refresh). I'm
trying to *not* break it. :)
That said, the unique token method is very interesting, I'll
definitely check it out. But I'm curious, if you check for an
existing token and do find one (so the user has possibly refreshed the
browser), don't you have to program a particular way to handle it? And
might that handling method be different for each type of action being
taken? Does this run the risk of overcomplicating the code as well?
Then again, being forced to consider and handle *exceptions* is a very
good thing when developing a stable application...

in some ways, this is a method to prevent those duplicate entries
in the db when someone refreshes the browser and reposts the data.
The only difference with richards code with what I have is that he stores it
differently than I generally do. The concept is as follows:
form.php:
?php
// generate a token
$my_token = md5(uniqid('thisformid', true));
// store the token in a place that can be retrieved
// on the next place, richard uses a db, i usually just use the
// _SESSION where it is stored isn't relevent
$_SESSION['tokens'][$my_token] = time(); // use time() so we can expire
// put the token in the form to be passed to the next page
?
form
input type=hidden name=form_token value=?php echo $my_token?
/form
action.php:
?php
// grab the token in the form:
$token = $_POST['form_token'];
// test it against what we stored in the previous page.
if (isset($_SESSION['tokens'][$token]) ) {
// forget the token
unset($_SESSION['tokens'][$token]); // very important
// do stuff..
} else {
// form submitted twice or they tried to access this page
// directly.. a no no.
}

Re: [PHP] Clear POST variables
I'm curious to hear what others say, but I tend to build into my
application flow a header(Location: someurl) redirect after a form
submission. It's just as if you were to include(somefile) the
resulting page, but by using header() you are moving the user away
from the action so that this sort of thing won't happen. In my
experience it also helps with a user's tendency to use the back
button--which is not wrong, it can just get in the way of rich
applications.
Cheers,
John

Re: [PHP] PHP Devel Environments???
Henrik, Why not use Smarty and create your own functions for your designers to use? That's one of it's purposes, after all. John Henrik Hudson said: Hey List- Any one have some input on some good GUI WYSIWYG devel enviroments for creating PHP scriptlets. The boss wants to lose the dependancy on the 2 programmers (myself and another person) for every little piece of PHP code. Of course, the graphic designers have no desire to learn source code, so we have to see if there are any WYSIWYG's out there that will allow them to create code chunks to either do webforms or handle simple variable passing between pages? My argument is that it is to wide open and there are too many variables that need to be taken into account for this to happen. We did look at Dreamweaver MX, but it's PHP support is limited to syntax highlighting and being able to insert if and else clauses. I'd tell'em to use gvim, but I don't think that would fly :) The boss says there are some Dreamweaver extensions for doing some of this stuff, but I still question their quality for open ended stuff like writing PHP.

[PHP] PHP Style Conventions
Looking for info on recommended PHP style conventions. I've seen the Pear style conventions, and they seem fairly good, but I'm interested in something that covers more ground, like what's the best way to name included files (*.inc?) class files, etc., what's the recommended dir structure for large projects (i.e., does efficiency decrease with greater numbers of include directories)?

Re: [PHP] Object In a class
Justin Mazzi said:
Can anyone tell me how to use an object within an object. Example
class blah {

then you want to use that class in a new one.
class blah2 {
var $test;
var $test2;
function do() {
$blah = new blah();
}
}
Well, you could use the blah object you created exclusively in function
do(), or you could create it as a attribute of your class and use it in
your instantiated objects, as:
class blah2 {
var $test;
var $test2;
var $myBlah;
function blah2()
{
$this-myBlah = new blah();
}
function do() {
$this-myBlah-test();

Because Crystal Reports is an overpriced rip-off. To get full web report functionality, you have to pay anywhere from $1-$10 for their enterprise edition.

Re: [PHP] Java call on object causes segfault.

where the backtrace captured in my email came from. If you'd like to veiw
the bug report, it can be found at: http://bugs.php.net/bug.php?id=21881
I'll try 4.3.0 and see what happens. I was holding back because I use the

soo, so might as well.
Thanks!

If the segfault exists here, write a bug report

[PHP] Java problem...need advice.
Trying to get java working so I can make native calls.
I've got php.ini setup and it seems to work (i.e., I can use the online
(php.net) example and create a java.lang.System object, and access
properties from it).
However, created my own class in a directory I specified in my
java.class.path directive and it doesn't seem to work. I get Document
contains no data. I can comment out the method call on $obj and it
prints my message, so I can only assume it's creating the object.
However, if I call a method on the object, I get the message. By watching
the task bar, I see the Connecting to localhost.../Sending request to
localhost sequence being repeated every 5 secs or so.
Can anyone help me out? I'd really appreciate it. See code below:

Re: [PHP] A Licensing Question
However - if you want to sell software under a closed licence you will need to be carefull to avoid 'linking' with gpl'd code. The problem is that 'linking' as used in the gpl seems to refer to C programming - and is an unclear term when refering to php. Yeah...that's really what I'm wondering. If I have my own code, but make function calls and the like to script libraries licensed under the GPL, does it mean my code will have to be GPL'd as well? It's not dynamically linking binary code in. I've read the GPL faq and it's very vague here. It considers interpreted programs data, but doesn't consider cases the that data is licensed under the GPL. Say, for instance, that I use a GPL'd library that provides a class called myGPLClass. If I create instances of myGPLClass in my own scripts, does that make my code in violation of the GPL? Damn, I need a law degree ;-).

Peter Hutnick said: Yeah...that's really what I'm wondering. If I have my own code, but make function calls and the like to script libraries licensed under the GPL, does it mean my code will have to be GPL'd as well? In a word, yes. Even if the script libraries are themselves just PHP scripts...not any binary code being linked into the interpreter? I'm still unclear here. Say, for instance, that I use a GPL'd library that provides a class called myGPLClass. If I create instances of myGPLClass in my own scripts, does that make my code in violation of the GPL? No. Use is not restricted in any way by the GPL. In fact, you needn't even /agree/ to the GPL in order to use GPLed software in any way you'd like, only to (re)distribute it. Hmmmnow I think I understand what you mean, but if I consider it in the context of my question and with your above statement, it seems contradictory. I don't think it's that you're misunderstanding me...I think it's me misunderstanding you ;-). Let me lay it out: Say you create a set of class libraries, called PeterLib, and release it under the GPL. I download these libraries...like what you've done...and decide to use them in my development. Your library makes available a class called FooBar that I really like, and I decide to make use of it in a number of my own files. So, one of the core files in my application contains: ? require_once(/PeterLib/FooBar.inc); $myObj = new FooBar(); $myObj-getFoo(); $myObj-printBar(); ? Now, futher assume that I want to sell my application under my own company's license and I label all my files as such, but still retain your GPL license it the PeterLib files. I rush to market and have an overwhelming amount of customers in the first month. Four issues: 1. Have I violated the GPL by distributing your code with my propietary, non-open source app? I'm still distributing source, but my specific files (including a few that call PeterLib classes) are not GPL'd. 2. If I decided to only distribute my own source for money under my own propietary license, but told my customers that in order for my application to function correctly, they'd need to download PeterLib. Is this a violation? 3. If the above are considered violations, I assume only using libraries licensed under licenses like the LGPL or PHP would make it safe for me to redistribute with my proprietary app? 4. How do the above change if/when I decide to encode my self-written files with Zend Encoder? Thanks very much for all your input. Very helpful. I really appreciate it.

Re: [PHP] A Licensing Question
Chris, Sheesh. I'd read it about 5 times but revisited just now. Somehow I missed the key phrase which are themselves interpreted.. Here's the full relevant excerpt: Another similar and very common case is to provide libraries with the interpreter which are themselves interpreted. For instance, Perl comes with many Perl modules, and a Java implementation comes with many Java classes. These libraries and the programs that call them are always dynamically linked together. A consequence is that if you choose to use GPL'd Perl modules or Java classes in your program, you must release the program in a GPL-compatible way, regardless of the license used in the Perl or Java interpreter that the combined Perl or Java program will run on. That answers my question. If following the scenario I described previously, my code would have to be GPL'd as well. Thanks!

I *think* I could integrate Jasper into my app fairly well with PHP's ability to call Java classes, but wanted to hear from anyone else with experience in this area.

[PHP] Speed concerns with OOP and PHP4
I'm working on a large VB/Sql Server to Php/Postgresql conversion (approx. 60k lines of code). I'd like to design this thing as OO as possible, because I think ultimately it leads to better, more extendable and readable software. However, since php does the whole copy thing with objects, I'm a little concerned. Is this deficiency on the part of PHP 4 something I should be concerned about? If I have a 60k loc fully object-oriented php app with a large amount (approx. 500 or so) queries to a db, am I making a mistake by going OO? Will it really slow down the app *that* much, or consume memory like a pack of hungry piranhas? Thanks for the input, guys.

[PHP] Gotchas with Php and Postgresql?
I'm preparing for a large project in which I'm the sole designer/developer. I've just about made the decision to go with Postgresql, as part of the project is converting a MS Sql Server db to a open source db and I think Postgresql provides some features that will make this port easier. However, just wondering if there're any gotchas I need to consider here. I'm definitely using PHP to write the app, and I can attest to PHP's great support for mysql (used it many, many times), but I have no experience using it with Postgresql. While I suspect that it's just as easy to work with via PHP as is MySql, I'm looking for any hardened, trenches-earned wisdom anyone would like to bestow. Thanks very much.

Re: [PHP] Zend IDE vs. PhpEd
I've tried phpEdit, but unfortunately it's a Windows-only IDE and has quite a few reproduceable bugs (I get an access violation almost everytime I use the latest version.

Re: [PHP] MySQL vs PostgreSQL
See MySQL 4.x. They also have subselects now (HUGE!). As for an Well, not really. Nested queries are scheduled for 4.1. 4.0 is in gamma, 4.1 isn't even available for download as alpha. You'll have to go with Postgres for now if you need subselects. Regarding row locking and transactions, look at the InnoDB table type, which is fully ACID compliant.

[PHP] Designing in PHP4 with PHP5 in mind...
I'm preparing for a project in which I'll be porting and redesigning a large, ugly Visual Basic/Sql Server app to a PHP/Mysql or Postgresql based web application. I'd like to code in a way that will be at the same time easily ported to PHP5 and that will take advantage of PHP5's new object handling efficiencies. I've read varying reports of whether syntax will be different. Is there anything I should watch for, add, or specifically avoid while coding this application to make the transition as easy as possible? Thanks!

[PHP] Zend IDE vs. PhpEd
Can anyone who's familiar with both give an honest, open evaluation? I'm in a rush project and need something quickly (have to purchase tomorrow), but I'm on the fence when it comes to these two products. Zend costs $100 less than Phped, so I'm leaning that way. But if there's anything you know that could make my decision easier, please forward it on. They seem pretty comparable, with the exception of PhpEd's db browser. Thanks!

Re: [PHP] Zend IDE vs. PhpEd
Sterling, Thanks for the reply. I'm also impressed with Zend's autocompletion...I can't even get PHPEd to autocomplete on objects. I wonder if Zend uses dbg as well. It'd be nice to see a profiler thrown into a future version. Finally, one frustrating thing on the part of both editors is the inability to autocomplete on arrays of object references...but I suppose that's a little difficult with a dynamically typed language.

[PHP] Where the hell did my session vars go?!?
I'm having serious issues with session management in PHP and am trying
to
determine if it's a problem with my hosting company or a problem in my
code.
The flow of my site is:
login_page - session_start_page - form_page - display_results_page
Upon login a POST is made to session_start_page. This page checks that
the user
exists in the database and then creates a session and populates a
session
variable ($session_id) to 123456. session_start_page then calls
header(location) to forward to the form_page. I output the $session_id
for
debugging purposes on every page following the session_start_page
The problem occurs as such:
Upon initial login, when the user reaches the form_page the $session_id
is
populated and prints 123456. However, when a user submits the form
and a GET
is made to display_results_page, the $session_id has been deleted (i.e.,
prints
no value). Since my code relies on the $session_id variable for
security, this
causes the user to be forwarded to an intermediate error page and then
back to
the login_page.
Upon the second login, everything functions as I would expect it
to...the
session_id variable is populated on every screen and no error occurs.
At first I thought the problem might be the version of PHP my hoster was
using.
Up until a week ago, the version was 4.0.4pl1. However, the server was
upgraded
to PHP 4.0.5 last week. Now, the problem seems to be fixed in Netscape
4.07 but
still occurs when using IE 4.
I'm at a loss. I've done quite a bit of research in to this problem and
haven't
found an answer. Any help anyone could provide would be much
appreciated. The
code is as follows:

Re: [PHP] IIS5.0/PHP4.03 killing all sessions. HELP!!!!
I have this problem as well (see Where the hell did my session vars go?). We were using 4.0.4pl1 and it was occuring under both Netscape 4.74 and IE 5.5. We upgraded PHP to version 4.0.5 and everything works nicely under Netscape, but IE 5.5 is still screwing up. Just for info... Thanks, John Diego Fulgueira wrote: Hi!. I have the following problem (we are going crazy about it!!) and i think there's many people out there that have experienced the same thing: A session created in one page is killed on the next one. Check an example: PAGE 1: session_start(); session_register(myvar); $myvar=hello; PAGE 2: session_start();//A new session_id is generated...!! //...Instead of using the already created one...! //...Even when PHPSESSID is passed on as a get-variable!!. echo $myvar; //$myvar does not exist!!!. echo $HTTP_SESSION_VARS[myvar]; //$HTTP_SESSION_VARS[myvar] does not exist either!!!. Here are some configuration parameters I am using: session.use_cookies ON (I tried OFF also without success). session.auto_start OFF (I tried ON also without success). session.use_trans_sid ON (I tried OFF also without success). register_globals ON track_vars ON HERE ARE SOME CLUES: 1.The session files in the server are being written fine, their contents look fine MOST of the time, although sometimes not all session vars or values are being written or files are empty. Read and write permissions in the directory have been double checked. 2.Sometimes sessions last trough one or two pages after the first session_start(), but then they are killed on each and every page. HELP PLEASE!! Any ideas will be greatly appreciated since I've tried almost all that has come to my mind. THANKS A LOT IN ADVANCE.
