I have spent quite a few hours searching with google, but I am still not
sure how to resolve my problem described below:
I am parsing an XML file with SimpleXML (PHP 5.0.3/FreeBSD STABLE-4/i386).
It appears that my internal entity references do not get expanded. I see the
same behaviour with SAX and PHP5.0.3, while it was not a problem with SAX
and PHP4.1.2.
See below, the 'title' gets added to the array, but not the 'price' and
'weight'.
I assume that libxml will expand the entity references? I see the value of
'price' and 'weight' of I look at the data returned by the parser with
'print_r'.
Anybody got an idea where I have gone wrong?
########## XML file ##########
<?xml version='1.0' encoding='iso-8859-1' standalone='yes'?>
<!DOCTYPE prod_desc
[
<!ENTITY dvd '
<price>14.95</price>
<weight>6</weight>
'>
]>
<prod_desc version='1.0'>
<prod item='C107D'>
&dvd;
<title><![CDATA[No more Diapers - DVD]]></title>
</prod>
</prod_desc>
########## PHP code ##########
foreach ($xml->children() as $item)
{
$item_attr = $item->attributes();
foreach ($item->children() as $element => $cdata)
{
// This will not work, bug in PHP
// $prod_array[$item_attr][$element] = $cdata;
// Workaround
$prod_array[eval("return $item_attr;")][eval("return $element;")] =
$cdata;
}
}

Hello,
I am interested on Artificial Intelligence for PHP, pattern maching, etc.
More specifically: data mining, statistics and pattern maching.
Couple of years ago there was a presentation on the MELL Extension - AI
for PHP.
I've tried to google it but I've found no code or examples.
Does anyone have any knowledge on using PHP for AI systems or know of
any resource, a book
or on the internet that might help me out?
Thanks in advance,
C.F.

I would like to be able to alter the lining-up of several sections on a php
generated webpage. What would be the best/optimal approach in achieving
that?
As an example "sections" referred to are mostly tables generated via code on
data obtained from a DB. Should I name them (somehow), shall I use a
seperate table to store the lining-up information or shall I add a
"precedence" integer column to each relevant table in the database, ...?
sorry, driveby answer.
you want to make your output (source) HTML look pretty?
2 options spring to mind:
1. the Tidy extension (there are probably other similar tools)
2. don't bother - as long as its syntax is correct indentation
is irrelevant really.
or do you mean something else by 'line-up'?
Thanks in advance for your guidance.

Hi Jochem,
Intention is to give a user the option of assigning "position" of a
"section" on the page, i.e:
First: sectA, then sectC, then sectE, then sectB and sectD.... or any other
order that is indicated by the user. So it is somewhat like top-of-page,
mid-of-page etc but with a numbering/precedence/sorting (can be named any)
system that populates the page according to the choice.
Roughly:
<--first section-->
<--second section-->
<--third section-->
<--fourth section-->
<--fifth section-->
etc... Clearer now?

Alp:
You can implement a weights system, similar to Drupal. In such a
system, each item is given a weight -- the lighter the item floats to
the top, and the heavier items sink to the bottom. Weights can range
from anything (lets take -10 to 10 -- 0 being the default). 1 is
"heavier" than 0, so any item with a weight of 1 sinks below any item
with a weight < 1. -1 is lighter than 0, so it will float above both 0
and 1.
This type of system is good if you are not concerned with strict
placing of items, since two items in the same weight category are simply
stacked on top of each other.
Regards,
Burhan

Hiya -
I want to create a class that inherits from a database object.
eg I have my own "user" Class, with general methods that do calculations etc.
However, it also reflects a table of the database, eg "age, location".
I want some methods called on the object to be handled by my class, but other
so at constructor time, something like
$this->parent = mysql_fetch_object($res); // returns a mysql obj with
age, loc etc records
then ...
$age = $userObj->age; // this actually comes straight from the dbase obj
$rating = $userObj->rating; // a public var calculated at construction
$life = $userObj->getSpend(); // this is a method to do a calc.
I could use a component (is the right OOP pattern word?)
$age = $userObj->dbObj->age
but I wanted to hide where the items are coming from. Also i want to
be able to just keep adding to the database without having to create
gettter/settter functions for everything...
I think python had some nice means of doing get/set functions
transparently, does PHP5 have anything like this?
thanks!

I believe the correct term for this is an object.
but I wanted to hide where the items are coming from. Also i want to

PHP5 does have get and set functions (
http://www.php.net/manual/en/language.oop5.overloading.php ) however,
your problem might be extrapolating all the properties of the object,
because if you change your database structure, then you wil have new
properties in $dbObj.

If you can connect with mysql_connect(), its using the old password switch.
