Re: [PHP] Do you use a public framework or roll your own?
I usually roll my own, unless there's a free lib / cms that does the trick near-perfectly, and is well-written (so extensible) About 80-90% of my tasks require me to use one of my own frameworks (i have 2, one "simple" and one with many graphical gimmicks), and i re-use / improve the mid-level functions & 3rd-party (free) libs. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Do you use a public framework or roll your own?
Shortly ago, moving from programming in Gtk+ / C++ to PHP for the first time in my life, I made a good study of the available rapid application development options out there, studied a few PHP frameworks, read the opinions on the internet about it, then initially decided to use a framework to speed up development. After more thought I then began to feel that such a framework could somehow lock one in into their way of doing it, and if one wants to do something a bit different, there would be a struggle with the framework's way of doing it, and ended up not trusting frameworks for the purpose on hand, so at the end of all, it was decided to start from scratch, gather object oriented and procedural code from the internet to use as examples, then design based on that.

I amended Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex::addComplexType().
Changing the (sic) ...
throw new Zend_Soap_Wsdl_Exception("Infinite recursion, cannot nest
'".$type."' into itsself.");
to ...
return "tns:$type";
and all is working just fine.
Obviously, I may be breaking something here, but I've not come across
it yet. Early days !

What I would do is use PHP to do any of the server-side operations, like connect to MySQL and arrange the data, and then have PHP output the XML.

[PHP] Multiple Class Inheritance
Hi All, I know that a class can only inherit from one other single class in PHP, but how would I go about simulating a multiple class inheritance? For example, if I had several small classes that dealt with things like form generation, navbar generation, etc, how could I create a class in which these all existed? Or am I thinking about this the wrong way? Should I have keep the smaller classes, and have one larger object containing instances of each as and how are necessary? I've used classes before, but I'm fairly new to class inheritance, and more particularly, the complex inheritance like I describe here. Thanks, Ash http://www.ashleysheridan.co.uk

Sorry, this is out of date and wrong. [] is the currently recommended way to do
string indexing, and {} is deprecated. See the Note at
http://php.net/manual/en/language.types.string.php#language.types.string.substr.

I doubt that the generated page depends on a petabyte of data but a subset of that and thus you don't need to transform petabytes. Even if you got the hardware for it any other coworker with a clue would kick your ass, drag you out to the parking lot and change locks.

Re: [PHP] Multiple Class Inheritance
If you want m-inheritance, you can "include" (encapsulate is the word i think) your smaller classes in "midware" and "big top-level" classes that expose (part of) their interfaces. It's easy. But guard against creating too many dependencies between different smaller classes to and "bigger" classes. Logic extending the features of more than 1 smaller class for a special use-case should be in a "bigger" class that loads instances of the smaller classes. Do consider building 3 to 5 layers of encapsulation, when 2 seems not enough. A class that includes & extends features for 2 to 4 "small classes" is better than a class that includes 50 "small classes" for widely varying features. Logic extending the features of just 1 smaller class, even for a special use case used only once, should be placed inside the smaller class (possibly activated by an $options=array(), or maybe by adding "_descriptionOfUseCase" to the function-name. That may seem to lead to bloat, but zend will take care of that. Ultimately, classes should provide abstractions of top-, mid- and lower-level areas of business-logic. They "govern" a "problem-area". Case in point; adodb.sf.net; it does database abstraction, for many different server types, and nothing more than that. It's "finished", because all the "use-cases" you'll ever encounter in the "problem-area" have been coded into adodb.

Re: [PHP] Multiple Class Inheritance
Oh, and i'd allow 1 (or _maybe_ 2) "very big" super-class(es) at the top level of a framework / cms, that do include 50-100 smaller classes. "midware" classes can evolve (be extracted) from the superclass, as your app evolves. Try to keep groups of functions relating to as few smaller/lower classes as possible, to allow that to happen naturally. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This is certainly correct, but it should also be noted that my original code used it once (thus, it was in fine form) and it was only to demonstrate a small field of results. Still, though a different discussion, it's worth reminding folks to audit their own code to see how many places they have unnecessary calls to count() when cycling through the same array in multiple places. Someone should start a "Pointers For Newbies, Reminders For Oldies" thread on the list and let everyone participate with what should be obvious - but are often overlooked - points within coding practice that can cause the programmer to develop bad habits and bad code.

Re: [PHP] Multiple Class Inheritance
1, you can implement multiple interfaces
2, you may want to return object instead of extending classes,
eg.
class Small_Class_Abstract
{
public function getFormGeneration()
{
return new Form_Generation();
}
}
class Small_Class_A extends Small_Class_Abstract
{
}
$A = new Small_Class_A();
$form = $A->getFormGeneration()->newForm();

"... should be obvious - but are often overlooked - points within coding practice that can cause the programmer to develop bad habits and bad code." - Dan Brown Tip #1: Don't use count() in loops unless there are very few items to count and performance doesn't matter, or the number will vary over the loop. That is, don't do this: for ($i = 0; $i < count($items); $i++) Instead, do this: $number = count($items); for ($i = 0; $i < $number; $i++) Reason: when you use the count() call at the top of the loop, it will re-evaluate the number of items each time it's called, which usually isn't necessary and adds time.

What about using the right type of quotation marks for output:
I use double quotes(") if I expect to output variables within the
string, and single quotes when it's just a simple string.
It's only a general rule of thumb and shouldn't be adhered to
absolutely, but I remember a thread a while back that showed the speed
differences between the two because of the extra parsing PHP does on
double quoted strings.

That should be on the stackoverflow.com
It compare the string parsing with or without variables embeded
and the important of comma operator when ` echo ` data
use
echo 'something', 'other'
but not
echo 'something' . 'other'

There is a big difference between using a comma and a period. A period
(.) actually concatenates the strings, whereas a comma only adds it to
the echo stream. So, if you were trying to assign the joining of the two
strings to a variable, you would have to use a period, as the comma
would throw a syntax error.

}
is a very common way to handle that.
Of course...
foreach(range(0, count($a)) as $i) {
}
is an alternative.
You can see the effect of the counting if you replace ...
count($a)
with ...
mycount($a)
and have ...
function mycount($a) {
echo 'Counting : ', count($a), PHP_EOL;
return count($a);
}

And for the most part, you'd be right but it still isn't good practice to *not* teach something strictly because it's not entirely significant. For example, polio has been all-but eradicated, but it doesn't mean that we should stop vaccinating against it. By ignoring a problem because it seems insignificant, you allow it to once again become a problem by not properly guarding against it. So even if it's just a bare mention, it's still worth that mention. Now, would I be all for a chapter on it? Probably not. ;-P -- daniel.br...@parasane.net || danbr...@php.net http://www.parasane.net/ || http://www.pilotpig.net/ Looking for hosting or dedicated servers?

I'd imagine that to something like Facebook, every split-second of optimisation is worth it, as even a 100th of a second becomes minutes of wasted time over the course of a few hours when you consider their volume of users, even with caching. One would expect that Facebook uses a bytecode cache... possibly one with an optimizer... the issue is very moot at that point since the difference will be optimized away at parse time.

Right. That, and the translation factors are the two most important things to mention. Further, translatable quotes take longer to process because they're first evaluated for things to translate. This only equals out to a few FLOPS, but when increasing by magnitude, the FLOPS are increased exponentially as well. And add on a few more FLOPS for each translation, such as escaped quotes and dollar signs. -- daniel.br...@parasane.net || danbr...@php.net http://www.parasane.net/ || http://www.pilotpig.net/ Looking for hosting or dedicated servers?

Re: [PHP] Pointers For Newbies, Reminders For Oldies
I'd like to add that when dealing with large memory structures,
usually arrays, combining them is fastest when done like this:
$array1 += $array2;
This will not always produce correct results when dealing with arrays
that contain identical keys, but for non-overlapping arrays it is far
faster than array_merge()
And if your script needs to pass large (> 5Mb) arrays around to
functions, be sure to use passing-by-reference; failing to do so can
double your memory requirements,
possibly hitting the ini_set('memory_lmit', ??)
$arr = array ( /* much data */ );
function workerFunc (&$data) {
//work on $data, as you would normally.
}
workerFunc (&$arr);

This would probably be the simplest solution for your original question -- much simpler than modifying the source code, or redirecting the output. It is also an excellent (in my opinion almost essential) method of doing a sanity check on any new page design, especially if it is at all complicated. On a number of occasions I have discovered PHP diagnostics hidden in the HTML which don't appear on the screen at all, and it is amazing how badly the HTML can be off without disrupting the screen appearance.

I'm not sure why your emphasis on the static .html page -- it doesn't seem necessary -- but what you are describing is somewhat like my new engine, which is used in the page www.corybas.com. This effectively incorporates a database, although all the data is stored in simple text files. It only has one page, but this can be modified to do wildly different things by specifying different parameters. The Engine has an address book/mail merge facility which is far more useful (and far quicker) than Microsoft's monstrosities, but this is not on show because I would have to generate a large list of bogus people to demonstrate it. It also has good facilities for editing the data files, but these again are difficult to demonstrate publicly. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Don't forget that changing some characters can actually change the words
and meanings of words. While an ë might look like and e, it's actually a
completely different character, with a different pronunciation to go
with it.
Is there some particular web service you're using that doesn't support
utf8 character sets?

"is a" and "has a" normally solves these composition vs inheritance questions in a second or two. perhaps a bit of studying on composition vs inheritance and common OO design patterns would be suited; also consideration for separation of cross cutting concerns | in fact a bit of reading up on java design patterns would be recommended; it'll stand you in good stead. the core J2EE Patterns catalog is well worth a look: http://java.sun.com/blueprints/corej2eepatterns/index.html Also Martin Fowler's pattern catalogue and indeed articles are worth going over: http://martinfowler.com/eaaCatalog/ and for a general overview: http://en.wikipedia.org/wiki/Category:Object-oriented_programming finally, from the very limited details it sounds like implementing an 3-tier architecture where you stick application code in one tier and presentation code in another would help abstract things a bit for you; the classes you've mentioned sound very much like Utility or Helper classes which would normally be called by methods which couple all the functionality together. Each class and method needs to be considered on a case by case basis; many will be able to be called statically and thus no composition is needed; on occasions where you need to call several methods from one instance within a single method then instantiation within that method will suit; and when you need to access instance based functionality across multiple methods in a class then composition (or perhaps inheritance : see is-a has-a) will suit. regards! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Don't use count() in loops unless there are very few items to count and

hate to point this out but the Ultra-modern version is counting from
0-10 rather than 0-9 or 1-10; thus it's got an extra item from somewhere :p

Re: [PHP] Reports generator
I actually started on a report class yesterday, and I have a few questions,
but first some details:
- Reports will be on user orders (ticket reservations).
- Need to be able to build a large variety of reports based on existing data
+ Orders by a specific user
+ Orders for a specific product (event)
+ Orders by a user sub-group (organization)
+ Orders by a user super-group (school district)
- Reports need data from a primary table (orders) and several secondary
tables (users, order_lineitems, etc.)
Now, I started to approach this with a class that builds an HTML table with
the data as the end product, based upon the parameters I supply.
There shall be a table_header property which will be an array of column
names, a rows property which will be a bi-dimensional array which will
contain the data for each row.
I want to have methods like the following:
createNew('orders', 35); // STARTS AN ORDER USING `orders` TABLE -
SHOW ID 35
$Report->addColumn('contact'); // USERNAME - `users` TABLE
$Report->addColumn('phone'); // USER'S PHONE NUMBER - `users` TABLE
$Report->addColumn('quantity'); // TICKETS REQUESTED - `order_lineitems`
TABLE
// SAVE OBJECT TO `reports` TABLE
$report = serialize($Report);
$success = mysql_query('INSERT INTO `reports` (`data`) VALUES (\'' . $report
. '\') ;');
if ($success) { $Notify->addtoQ('Report succesfully saved.', 'confirm'); }
else { $Notify->addtoQ('There was en error saving the report.', 'error'); }
?>
I was having a tough time wrapping my head around how to make the report
class less specific and more flexible. For example, I have the user's
user_id already stored in the `orders` table (of course, foreign key), but I
want to display their username (or firstname, lastname pair), which would
require another call to the `users` table, so I had a $queries property,
which would be an array of queries to execute, but then I couldn't figure
out how to handle each one, because each is handled uniquely.
So, I have to be less general, and more specific. Call what I want by
nickname, ie. $Report->addColumn('userRealName'), and have a switch
statement within the addColumn() method to check for nicknames. Whew! That
sounds awful!
And how do I handle each result in the queries array? Should I create an
associate array (ie. 'username' => 'SELECT `username` FROM `users`',
'school' => 'SELECT `name` FROM `organization`... ') and again, have a
switch statement to determine how to handle the database result arrays?
Can anyone point me in the right direction? Should I just get down and dirty
and write a focused class (or even procedural?) for different types of
reports that I anticipate needing?
This is a tough one! Thanks!

You don't have to make a separate query; you can do a join. The problem
is how to handle it in a class/method way.
Honestly, what you're trying to do is very tricky. My suggestion is that
you do iterative development on this (I'm sure there's an erudite
programming student name for this which I don't recall). For example,
rather than doing addColumn() methods, use a rowQuery() method, and feed
that a query which will work for each row. If you like, you can allow
for "place markers" for variables, like '%ordernum%'. When you invoke
the generate() method (or whatever) have it parse the query for those
place markers, and substitute the values you supply. Then feed the query
to MySQL and capture the results in a 2D array.
Now write code which will iterate through your rows and columns and
insert them into HTML tables.
If you like, you can write a child class for each report, which inherits
from a common parent reports class. At this point, I'm not sure how much
use that would be, but you could do it.
Once you've done this and gotten it working for all your reports, you
then will have a better idea of what exact kinds of problems you're
going to run into. Then start on version 2.0, where you use that
information to build a better class with addColumn() methods, etc.
You might also consider snagging a report generation class (or somesuch)
from a place like phpclasses.org and seeing how *they* handle this.
Adapt the ideas to your needs.
I'm sorry if this doesn't help. This is just how I'd do it. The kind of
problems you're trying to solve are too abstract for my comfort, and I'd
want to get something working first which highlights the difficulties
before I tackle a full-on "pretty" OO solution.
(The other reason I'd do it this way is that I used to work for a
company that sold a report-writer coded in C. I never realized the
complexities of reports until I'd worked with that product for a while.
Subtotal levels, grand total levels, headers, footers, column labels,
gathered from a variety of COBOL, C, BASIC and other databases. Ugh.)

Re: [PHP] Reports generator
Allen, i think your primary design consideration is this;
> - Need to be able to build a large variety of reports based on existing data
This would lead me to jump at a 'plugin' solution.
I'd make:
- 1 superclass as interface to the rest of your webapp(s)
- 1 "top-class" that has the logic applicable to all reports.
(or just 1 top-level class, if you want)
- 1 to many plugin classes, that all use the same simple interfaces.
By using arrays as options/return-results, the whole thing becomes
extensible without breaking compatibility.
I'm working on a newsscraper (same problem basically, doing both input
to db and output from it) and for that i'm not even using classes. I'm
using plain-old functions with a specific naming convention in files,
also named according to a convention.
Some examples of plugin functions exposed in 'plugin.news.digg.php':
function plugin__news__digg__pages($mp)
function plugin__news__digg__isValidPage ($page, $pageContent)
function plugin__news__digg__parser__siteHTML ($page, $pageContent)
$mp = user-level parameters (from the superclass)
__pages returns a simple array that tells the top-class which pages to
curl (and with which parser-function (like __parser__siteHTML)),
before passing $pageContent along with $page (a conventionized
meta-data array, mostly built up by __pages) to the parser function
__parser__siteHTML.
All parser functions return an array that the top-level class can use
to insert their "hits" into the db.
Plugin functions can be called by $func =
'plugin__news__digg__parser__siteHTML'; $func ($page, $pageContent);
In your case, Allen, i'd start with plugins that accept user-level
parameters (both generic and specific in the same $options array, and
to prevent confusion through feature-creep, use more than 1 level in
the array) and then output HTML. Try to use CSS effectively.
Using the smarty library in plugins' HTML generation functions is
probably overkill, but some people like such midware.
Your top-level class can take care of any caching of finished reports.
Your superclass is responsible for building up the "frame" of the
webpage that holds the reports.
If two or more plugins need (almost) the same data, consider building
a datastore class, that sits "below" all the plugins (and the
top-class).
And i highly recommend adodb.sf.net as the db-abstraction layer, to be
used exclusively for all db access by all other classes.

Re: [PHP] POLL: To add the final ?> or not...
I'd give short-but-descriptive variable- and function-naming a much higher priority than something that not really affects code-reliability. And i'd insist on doing all names and comments in english, even if it's broken english. It makes code much easier to be taken over by someone of another nationality. If i'm paying for code, it would be on the top of my list of demands. After that, i'd insist on the (beginner) programmer properly commenting his code; "explain the code you're about to execute as you would do in a brief manner to a layman/child, but let proper function & parameter naming take care of as much of the "explanation" as possible". Cryptic code = BAD code, imo. My comments (per loop of about 50 lines) are almost never longer than 3 lines of 80 chars. Mostly just 1 line. So if i had to work with a beginner programmer, i would not give them hassle over not closing their PHP tags. On the other hand, i wouldn't really trust a mid- to advanced-level programmer if he/she wasn't able to close their tags and make sure there's no whitespace behind it. That kind of laziness/clumsiness will lead to time-consuming mistakes elsewhere while building even moderately complicated code. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Curious PHP cli output in context of bash completion ?
The problem has nothing to do with "myscript.php" output. The problem is in bash completion process wich involves only "echoscrip.[php|sh]". These scripts only have (to my comprehension) to output a single string, without newline and it is what they do. The fact is, and I do not understand why because the output is exactly the same : - using echoscript.sh to provide bash COMPREPLY variable value, bash completion works, - using echoscript.php to do the same, bash completion does not work. I tried to took for a runtime option (php.ini) but didn't found anything relevant. PS : just because I had to do it, I tried to add newline and cariage return to all the scripts. The result is the same, unfortunately.

Re: [PHP] Curious PHP cli output in context of bash completion ?

In this context (to my mind), it is quiet normal and simpler to get bash completion variables value from the PHP itself.We could probably continue to discuss this design issue but the problem is that, in the context of bash completion process, echoscript.php and echoscript.sh that simply echo "a b c d" (exactly the same output), give different results and I can not understand why ... I searched for runtime options (php.ini) but didn't found anything relevant. I also searched about the "shebang" but with no result.I just attached a modified version of completion.sh, the script to source in the current bash process to complete "myscript.php" (see http://ubuntuforums.org/showthread.php?p=8734334 for a complete description).If you uncomment the lines that call echoscript.php and echoscript.sh, you can compare php.out and sh.out files and see they are identical (using "diff -b php.out sh.out" for instance). When echoscript.php is not called, the bash completion process works. When it is called the completion goes wrong, even if you do not use the output in the completion process (the modified version of completion.sh uses a "static" bash string "a b c d").Can anyone understand what could happened ?Thank you, completion.sh Description: Binary data -- Alex
