Using AJAX With A PHP Front Controller
I have a framework that uses the front controller design pattern for a
single point of entry to the application and the autoload function for
includes. I am trying to incorporate AJAX into the framework, but the

instantiating classes.

Best Xmlrpc Implementation
Can anybody recommend the best xmlrpc library for php? My observations
so far are that:

* the PEAR XML_RPC package is undocumented
* the php xmlrpc extensions are undocumented and require downloading
extra code for the client functions
* the usefulinc (http://xmlrpc.usefulinc.com/) is not supported by the
php team

LRU Cache Implementation
Most of my application's operations (including SQL queries and numerical
computation) can be cached. An LRU (least recently used) cache would fit
the bill perfectly.

This LRU cache should be preserved over multiple requests from the same
session. If possible, it should be seen across multiple sessions so that
all users can benefit from it.

I can't implement either solution. In principle I could preserve the
cache across multiple requests by using $_SESSION, but I don't think
this would be wise. The whole structure would weigh on the order of a
MB, so access would probably be really, really slow.

Also consider that access to the cache must be serialized.

I could in principle write the C code to do the caching. But this would
be extremely ugly since I want to cache PHP objects, not C structures.
There would also be the overhead of converting to and from PHP's
representation.

Has Anyone Done An SMPP 3.4 Implementation Or 3.3 ?
I need some guidance please on SMPP. I am completly new on that.
I wonder if PHP is going to be the right root to take. At the moment I
am having a look on Net_SMPP from PEAR but it doesn't make a lot of
sense Yet.
I succeed int sending a message but I want to have a constant bind and
get replies and reports if the messages sent have been delivered.

Is it much different to develop PHP for comand line execution rather
than the web ?

CMS - Category Page Implementation
I'm programming a basic CMS. Lets say there are three categories:

Headline News
Business News
Local News

I'd like there to be a category page which would display all of the content in that category. For example, on the "local news" page, I'd like it to display all the local news stories.

I know how to implement it so far but the one twist is that I'd like it to display only say 10 stories a page. One could click on the next or previous page to see the next or previous ten stories.

-> PHP4 Singleton Implementation Question <-
I'm trying to implement a singleton in PHP4 but it doesn't seem to
work. The object is recreated each time I call it.

The goal of the class is to keep a variable up to date.
It's used to display a database content, 25 rows at a time.
The singleton keeps track of the current starting row and
increases it or decreases it by 25 depending on the user action
(pressing a Next or Prev button).
Those buttons are submit buttons calling the current form itself.

But each time I re-enter that form, the singleton variable is created
again and therefore the currentRow variable reinitilized.

Here is the code for the class called Welcome:
---------------------------------------------
class Welcome {
var $offsetRows = 25;
var $currentRow ;
// ************************************************** ********
// INSTANCE function to instanciate this class only once
// ************************************************** ********
function &getInstance() {
static $instance ;
if( !$instance ) {
$instance = new Welcome() ;
}
return $instance ;
}
// **************************************************
// CONSTRUCT function called when object is created
// **************************************************
function Welcome() {
$this->currentRow = 0 ;
$this->offsetRows = 25 ;
}
// **************************************************
// SHOWRECORDS
// Displays the actual table with info in rows.
// **************************************************
function showRecords() {
// my table display code here using $this->currentRow
}

// **************************************************
// NEXTRECORDS
// Displays the next nn offset records
// **************************************************
function nextRecords() {
$this->currentRow += $this->offsetRows ;
$this->showRecords() ;
}
// **************************************************
// PREVRECORDS
// Displays the previous nn offset records if not at first
// **************************************************
function prevRecords() {
$this->currentRow -= $this->offsetRows ;
if( $this->currentRows < 0 )
$this->currentRows = 0 ;
$this->showRecords() ;
}
}

Then my form works as follows:
------------------------------
<FORM action="<?=$_SERVER['PHP_SELF']?>" method="post">
<?php
require_once( "class_welcome.php" ) ;
if( !$welcome ) {
$welcome =& Welcome::getInstance() ;
}

if(isset($_POST['next'])) {
$welcome->nextRecords() ;
}
else {
if(isset($_POST['previous'])) {
$welcome->prevRecords() ;
}
else {
$welcome->showRecords() ;
}
}
?>

<P>
<INPUT name="previous" type="submit" value="<<" />
<INPUT name="next" type="submit" value=">>" />
</FORM>

(Zend Engine) Array Implementation.
Does someone know how the array-type is implemented in Zend Engine?
I would say it is a hashmap or a kind of vector, but since numeric AND
string keys are possible I can't figure out how they made it.

Does someone know about it or know a place where to get that
information?

Php Configure File Not Present In Current LAMP Configuration - CURL Implementation
I run a few websites, and feel fairly confident about my PHP skills, but not so much with my Linux skills. We are running PHP 4.3.6, and I need to configure it to utilize cURL. I got cURL installed and configured on the server, but now I need to reconfigure PHP with the command:

./configure --with-mysql --with-apache=../apache_1.3.31 --with-curl=/usr/local/lib

The only problem is that my confgure file is not present in the PHP directory. I'm not sure where to go with this. I'm trying to get the site set up to be able to connect to Authorize.net, and I can't get past this cURL problem.

Does anyone have any idea what I need to do to get PHP configured to recognize the cURL functionality?

Getting Name Of New Of View From MySQL 5.0+
We are using MySQL 5.0+ because it now supports views. However it
appears that the PHP's(4.3) mysql_field_table() is returning a
temporary name table name rather than the actual table (view) name.

For instance we have a view defined as "open_meeetings_view", yet when
we do a mysql_field_table() the name retrieved is "#sql_7a3a_1". The
same call correctly retrieves all static tables and even aliases
correctly.

It does not appear that PHP has the ability to dig any deeper (maybe in
PHP 5.0?), but does anyone know how to query MySQL for this information
directly? A "show tables" does show the view names correctly. So we
just need a way to correlate the temporary table "#sql_7a3a_1" back to
the real view name "open_meeetings_view".

Directory-View With PHP
I've programmed an access-control via header()-function. It
checks an username and password in database ... nothing special.

Currently, the control gives access to a download, but I would
like to allow special users to view the complete directory.

AFAIK this is only possibly through ".htaccess" (Apache webserver).
But then, I need to create an entry for each user in the database
in the file :-(

Would it be possible to allow this direclty through PHP?
Of course, I could write dynamically into htaccess, but if
several users would access the file at the same time ... URGHS :-)

SQL VIEW Table

View All Plus Pagination?
i have a online store that has about 2800+ products  - on my productList.php pages I have a few variables to display the number of products per page:

<?php
$productsPerRow = 3;
$productsPerPage = 27;my boss would like a view all button that sets $productsPerPage to the total number of products  - and is active for as long as the SESSION (Perhaps unless the button is clicked again?)

Any Ideas on the best approach to accomplish this??

The Flyweight Pattern In PHP 5
Yesterday I continued my series of design patterns examples using PHP
5 with the Bridge Pattern. Here now is my 18th design pattern
example, the Flyweight Pattern.
In the flyweight pattern we conserve resources by sharing instances of
a class which are identical.

The creating of these instances is controlled by a factory which will
only create one if it does not already exist, and will return the
shared instance to the requestor.

---

Strategy Pattern Php 5
I am reading about the "Strategy" pattern. The concepts they intruduce is :

1. Favor composition over inheritance.

Does this mean? - as opposed to creating big classes that I will inherit from in the future, I should include only the most important things in the super class and use "composites" or classes that inherit to put details into?

2. Program to interfaces and not implementations.

One thing is: when you add a new method to an interface, you break all your clients, whereas with an abstract class you can add a new method and provide full implementation and new clients will inherit it.

The Mediator Pattern In PHP 5
I finally pieced together what I think is a good example of the
Mediator Pattern in PHP 5. See what you think.

I have, per request, tried to simplify my test program structure a
bit. testMediator.php has only one html tag in it - a <BR>. This is
in my new writeln() function, which adds '<'.'BR'.'>' to each line and
echos. If you just add a '<BR>' after each line the program would run
fine, but the source code would not display properly.

So, see if you like the new test structure better. Most of the other
PHP design patterns on www.FluffyCat.com/PHP-Design-Patterns still
have the old test formatting system, but if this proves more readable
I'll redo the others as well.

Pattern Matching
I have a web search form. If I put 'fred' in one field and in the database it has 'fred, bob, dave' in that field, I can bring up the record by using:

SELECT * from details where keywords LIKE '%$keywords%'
This works fine. HOWEVER If I put 'fred, bob, dave' in the search box, and it only has 'fred' in the database field THEN it won't bring up the record. Obviously I can't use:

SELECT * from details where keywords LIKE '%$keywords%'

any more, so what do I do?

---

The Strategy Pattern In PHP 5
I'm almost done my series of design patterns using PHP 5. Today's
pattern is the Strategy Pattern.

In the Stratedy Pattern a "family of algorythms" is used interchangably
by calling clients.

This is the second pattern in as many days as I've used my older work
with patterns in Java, and again I liked the old example when I first
looked at it, but now I wonder about it. In this example the context
is passed a parameter at instantiation, and the context then chooses a
concrete strategy which it hold on to for every time it needs a
strategy. This means that the calling client would need to call the
appropriate context. Not sure if this is the real intent here, might
have to revisit this one...

---

The Singleton Pattern In PHP 5
To add to my growing library of Design Patterns in PHP 5 I have
written what I think is a good example of the Singleton Pattern.

In the classic singleton pattern an object will distribute one and
only one instance of itself. This can be useful for the sharing of
resources such as a single db or network connection.

A variation, sometimes called a multiton, would distribute a limited
number of instances of itself. Useful, say if you had a limited
number of db connections to share.

MVC/OO Pattern Clarification
I had a question about OO implementation in the MVC pattern that is
directed at anyone who feels experienced with it.

My fuzziness comes from trying to learn OOP and MVC at the same time,
coming from a procedural background where I used neither. I promise
I'm not a dummy, and my logic skills are very strong, but this really
is a whole new world for me.

The Interpreter Pattern In PHP 5
Last week I continued my series of design patterns examples using PHP
5 with the Bridge Pattern, Flyweight Pattern, and Proxy Pattern. Here
now is my 20th PHP 5 design pattern example, the Interpreter Pattern.

In the Interpreter Design Pattern you define a language syntax, and
parse requests that use that syntax, and call the correct classes and
methods to handle the request.

An interesting pattern, although I don't think I've used it much in
systems I've worked on. It is probably indespensible if you are
writing a compiler.

---

Factory Pattern In Php
I want to use a factory pattern to create a variety of objects. Which object
gets created depends on a string that is passed to the factory create
method. I would like to avoid using an if or switch construct to accomplish
this but not sure how. For example,

....

if($nextObject == "login")
{
return new Login();
}
else if($nextObject == "validatedata")
{
return new Validate(aString);
}

....
Is there any way to avoid this?

---

The Proxy Pattern In PHP 5
This week I've I continued my series of design patterns examples using
PHP 5 with the Bridge Pattern and the Flyweight Pattern.

Here now is my 19th design pattern example using PHP 5, the Proxy
Pattern.

http://www.fluffycat.com/PHP-Design-Patterns/Proxy/

In the proxy pattern one class stands in for and controll all calls to
another class.

This could be because the real subject class is on another platform,
the real subject is "expensive" to create so we only create it if
necessary, or to controll access to the real subject class.

A proxy can also add access functionality, such as keeping track of
how many times a real subject is called.

Proxy is a nice little pattern, being both fairly simple and widely
used.

Pattern Matching
I have HTML stored in a variable $html Buried in there is a link with the anchor text as New York therefore in the $html variable somewhere is <a href="somelink">New York[/url]

Is there any way using pattern matching that would let me get the link used to link to the text New York?

There is a few links with the text New York but I only want to get the link from the first one.

Been agonising over this for ages so if anyone could help it would really save my life.
