[PHP] Using DOM object, how?
I was looking at the PHP DOM documentation here http://www.php.net/
manual/en/ref.dom.php (which is rather sparse in the way of
examples) and can't even get to square one.
Here's an example from the php site:
?php
$doc = DOMDocument::loadXML('rootnode//root');
echo $doc-saveXML();
$doc = new DOMDocument();
$doc-loadXML('rootnode//root');
echo $doc-saveXML();
?
Problem is, it chokes on the first line with the error:
Fatal error: Undefined class name 'domdocument' in /folder/

Anyone know how to use this thing?

Re: [PHP] Re: Javscript embedding problem
It might be a timing problem. It might take longer to load the file containing the code so that when the inline code is found and executed, the called function is not present. Notice that all the downloads of the bits and pieces of an HTML page proceed asynchronously and not sequentially. You should not assume that the call to a function will be done after the file is downloadad because it shows up later. The browser queues the download of all the external elements in the page, code, pictures, etc while it keeps downloading and processing the main download. They can easily get out of synch. The proper way to include and call javascript code is to include all code in the head and then make the call in the onLoad event of the body tag. This onLoad event is called when every part of the page is already loaded and, thus, the downloaded javascript file is assured to be available.

You should put the full URI, including http:// and your domain. Not
doing so violates the HTTP spec.
If you want to signal that the resource has permanently moved, put this

The first line of that page - The DOM extension is the replacement for the
DOM XML extension from PHP 4. makes me suspect that it may be a PHP 5
feature, and sure enough, a look in the changelog confirms this.

So if you are using php 5.0, that would explain your error.

I would be extremely careful with this.. because sadly PHP's XML generator
uses the short form whenever possible.
script / will *NOT* work in most browsers such as FireFox.
script/script Will work.
I personally would love to see a function where I could set it to use the long
form. and when importing if it's in long form.. set that long from flag on
automatically .. this would have saved me _hours_ of debugging work.
are you trying to just generate the entire html page using only the XML
DOM? .. or are you doing this in conjunction with another language such as
XSL?

You can probably add an empty text node to the script tag, or a text
node consisting of a single space, or something like that, to make it
use the long form.

I am running Linux on my home computer. The specific distribution is

I know that the current latest versions of these applications are as
follows:
PHP 4.4.0
do you 'abuse' references? if not then you should have no problem.
... you may have code that breaks on 4.4 due to fixes made to the core engine
of php...
e.g:
$var = array_pop( explode('-', '1-2-3-4-5') );
.. is bad code (read the manual page for array_pop very carefully) and would
work
in older versions but the engine has been tightened up to disallow such fauxpas.
MySQL 4.1.14
unless you are using very new features of mySQL I doubt you will have
compatibility problems (although be ware of the difference between the mysql
extension and it's replacement mysqli)
phpMyAdmin 2.6.4
wouldn't worry about this at all.one version will have a few more/nicer
features.
not a big deal :-)
I've already spoken to my web host and they intend to upgrade to the new
versions as soon as they build a compatible interface for them with
their administrator control panel interface.
don't hold your breath for that :-)
The Questions:
If I install the latest versions locally, will they be backwards
compatible enough with the versions on my host server?
mostly yes, some stuff will break. it depends on what your code actually does.
Would it be easy enough to install the versions that my host has, and
then upgrade later?
the release archive has what you need:

Any advice would be much appreciated.

Jochem,
Whoa... what do you mean by this, exactly? I am running PHP 5.0.4 and
$var is correctly set with the code you give above. I could not find
anything like you describe in the array_pop manual (see below).
Please elaborate on why this is bad code.

array_pop
(PHP 4, PHP 5)
array_pop -- Pop the element off the end of array
Description
mixed array_pop ( array array )
array_pop() pops and returns the last value of the array, shortening
the array by one element. If array is empty (or is not an array),
NULL will be returned.
Note: This function will reset() the array pointer after use.
Example 1. array_pop() example
?php
$stack = array(orange, banana, apple, raspberry);
$fruit = array_pop($stack);
print_r($stack);
?
After this, $stack will have only 3 elements:
Array
(
[0] = orange
[1] = banana
[2] = apple
)
and raspberry will be assigned to $fruit.

[PHP] Problem with mysql_connect(...)
Hello. I'm trying to connect to my MySQL server with mysql_connect(...). The server is up and running, and I'm running Apache with PHP properly installed. The code: $hleServer = mysql_connect($host, $user, $password) or die(Error: Database. Error code: 1. Contact the web master!); $host, $user, and $password are set to correct values (checked and double checked). The funny thing is that not only does the function call fail, but I'm not even getting the text defined by die(...). It seems that the function call is more or less a black hole. Of course the rest of the script doesn't execute either, I'm just left with a blank page. I didn't use to have this problem before (using PHP 5 now instead of 4). Thanks for any input on this problem... Arthur

You could always do this, unless you are set on using a regular expression:
if($num=0 $num=1.01){
echo number_format($num,2);

[PHP] RSS creator class

array_pop
(PHP 4, PHP 5)
array_pop -- Pop the element off the end of array
Description
mixed array_pop ( array array )
array_pop() pops and returns the last value of the array, shortening
the array by one element. If array is empty (or is not an array), NULL
will be returned.
Note: This function will reset() the array pointer after use.
Example 1. array_pop() example
?php
$stack = array(orange, banana, apple, raspberry);
$fruit = array_pop($stack);
print_r($stack);
?
After this, $stack will have only 3 elements:
Array
(
[0] = orange
[1] = banana
[2] = apple
)
and raspberry will be assigned to $fruit.

Re: [PHP] Re: Using DOM object, how?
I would be extremely careful with this.. because sadly PHP's XML
generator
uses the short form whenever possible.
script / will *NOT* work in most browsers such as FireFox.
script/script Will work.
Thanks for the heads up. Looks like if you define the tag like
$script= $dom-createElement('script',''); -- empty string
It tacks on an end tag.
I personally would love to see a function where I could set it to
use the long
form. and when importing if it's in long form.. set that long from
flag on
automatically .. this would have saved me _hours_ of debugging work.
are you trying to just generate the entire html page using only the
XML
DOM? .. or are you doing this in conjunction with another language
such as
XSL?
So far, just playing. But ultimately I'd like to generate the whole
page using dom calls. It seems much cleaner for what I'm doing than
creating a whole bunch of large functions that do nothing more than
echo prestyled html.

[PHP] Suggestions for class design
Hello,
Every time I write some classes I always come across the same
fundamental problem that I haven't figured out how to solve/approach
yet. I'm not exactly sure how to put it into words simply but here
goes...
Let's take for example a class called 'Customer' that (obviously)
manipulates customers in the database. Here is a very basic Customer
class. (Data validation and the like are left out for brevity.)
class Customer
{
var $id;
var $name;
function add_customer()
{
// create sql statement
$sql = INSERT INTO ...;
// create db connection
$db = DB::singleton();
// execute SQL
$db-execute($sql);
}
function delete_customer()
{
// create sql statement
$sql = DELETE FROM ...;
// create db connection
$db = DB::singleton();
// execute SQL
$db-execute($sql);
}
function get_customer()
{
// create sql statement
$sql = SELECT ... FROM ...;
// create db connection
$db = DB::singleton();
// execute SQL
$customer = $db-execute($sql);
// populate object variables
$this-id = $customer['id'];
$this-name = $customer['name'];
}
}
(Unless I've already got some major design flaws I think we should be
good to go.)
Where I get tripped up is when I realize I'll need to at some point get
more than one customer at a time and thus I want to add a method called
'get_customers()'.
Since an object should be a single instance of something (e.g. ONE
customer) how do I justify adding the method 'get_customers()'? Or
better yer, how do I properly add a method like that? (A method where
instead of using a SQL statement to return ONE customer's data I instead
return a record set with more than one customer.)
The class in its current state can't handle data like that so I have to
then rethink the design and a new object variable called $customers
where I store the record set that is in return accessed directly by the
calling page itself.
With the way I'm working with these objects now they seem less like
objects and more like an organized collection of functions.
I'd appreciate some actual code recommendations as I have a hard time
understanding the abstract descriptions of how objects should work and
be designed.
Thanks,
Chris.
Thanks!
Chris.

Here's an attempt:

$results = $db-execute($sql);

// populate it with data
$tmp-id = $v['id'];
$tmp-name = $v['name'];
// store it in array
$this-customers[] = $tmp;
}
}
function delete_customers()
{
// loop through array of customer objects ...
foreach($this-customers as $customer_obj)
{
// ... deleting each customer one at a time
$customer_obj-delete_customer();
}
}

Re: [PHP] Re: Using DOM object, how?
Rats. Looks like you can't encapsulate DOM objects in your own
classes. I tried this and the browser 'view source' shows a
completely empty document.
?php
$x = new MyDom();
$x-createScriptElement('howdy.js');
class MyDom
{
function MyDom()
{
$dom = new DOMDocument('1.0', 'iso-8859-1');
return $this;
}
function createScriptElement($inScriptPath)
{
$script= $this-dom-createElement('script','');
$script-setAttribute('language', 'javascript');
$script-setAttribute('src', 'howdy.js');
$this-dom-appendChild($script);
echo $this-dom-saveXML();
}
}
?
If the element adding code is in the same function as the dom create,
it works
?php
$x = new MyDom();
class MyDom
{
function MyDom()
{
$dom = new DOMDocument('1.0', 'iso-8859-1');
$script= $dom-createElement('script','');
$script-setAttribute('language', 'javascript');
$script-setAttribute('src', 'howdy.js');
$dom-appendChild($script);
echo $dom-saveXML();
return $this;
}
}
?
Also if the DOM object is declared outside the class, and class
functions access it as a global it works
?php
$dom = new DOMDocument('1.0', 'iso-8859-1');
$x= new MyDom();
$x-createScriptElement('howdy.js');
class MyDom
{
function MyDom()
{
return $this;
}
function createScriptElement($inScriptPath)
{
global $dom;
$script= $dom-createElement('script','');
$script-setAttribute('language', 'javascript');
$script-setAttribute('src', $inScriptPath);
$dom-appendChild($script);
echo $dom-saveXML();
}
}
?
Would be nice if you could encapsulate it though...
You can probably add an empty text node to the script tag, or a
text node consisting of a single space, or something like that, to
make it use the long form.

Hi Chris
Assuming that you have some procedural code, could you not create an
array of Customer objects?
I am not sure what argument would be passed to the get_customer function
as you do not have an argument in the function definition, but if it was
perhaps the customer name, you coud have something like :

[PHP] Installing under IIS6.0
Hello, all - This is a subject that I've seen pop up on the list a few times, but not in great detail about setting up PHP under IIS 6.0. What I'm trying to achieve here is to install PHP to process PHP code embedded inside of HTML pages. Under Apache, I'd just add .html to my AddType directive and call it good. I know I'd sacrafice some speed for a bit of functionality (and bad code), but that's a sacrafice that I need to make here. I've got PHP set up to the point where it will process files ending in .php, but I want to blanket the processing of PHP code under IIS in the same manner in which I blanket PHP code with Apache. If anyone has any suggestions, other than reading PHP's manual which I've read several times which does not cover this, I would greatly appreciate it.

There are lots of different approaches for implementing DAO's, but personally I prefer to use a DAO class that represents one entity in my database (in your example, the Customer), and then have another separate class which is responsible for data operations on my DAO (the peer class). (This is the approach that many existing ORM tools use, both in the PHP and Java worlds.) In other words, Customer is only used to access the data that has been retrieved, but Customer itself doesn't have any methods for retrieving, updating, deleting, or saving. The CustomerPeer class handles all the data operations on Customer. If you want a particular Customer instance, you ask the peer to retrieve it for you, and it returns the appropriate object. If you want to save changes to a Customer, you retrieve the right instance, set its attributes, then give it back to the peer class which handles the database interaction. So, the Customer class is completely ignorant of the database, and is only concerned with giving you access to the data that is related to that Customer (and any other app specific methods that it makes since for the Customer class to handle). The advantage to using this approach is that you can easily have your peer class return an array of Customer objects, each one representing only one customer. Chris W. Parker wrote: Well, yes I think it does, but what I'm missing is how this new object interacts with the original one if it does at all. And what would I call it? 'Multiple_Customers'?

Just use a normal PHP array of Customer objects. In your spare time, take a look at Propel (http://propel.phpdb.org/), an ORM for PHP5. I wouldn't suggest trying to introduce something like this in the middle of an existing project, but consider toying around with it for a future project. I used this for my last application with great success. It used 20 DAO's, similar to your Customer object, and Propel saved me a lot of tedious work in implementing all of the data-related methods+getters/setters for these 20 objects. If you have any questions about it feel free to drop me a line or check out the Propel mailing list which is very helpful.

Where I get tripped up is when I realize I'll need to at some point get more than one customer at a time and thus I want to add a method called 'get_customers()'. Yes, there is a problem. You are trying to retrieve objects into memory before they exist. It makes more sense that you retrieve objects using a factory class. That is the approach of Metastorage. You may want to take a looka at Metastorage before you reinvent the wheel. Metastorage is an persistent object class generator tool that lets you design your persistent object classes using a simple XML format that describes the classes, variables, validation rules, relationships and any functions that you may need to manipulate your objects. Besides the persistent object classes, it also generates a factory class that takes care creating new objects from scratch or retrieve them from the database. The factory class makes sure that each object does not exist more than once in memory. When you want to retrieve a collection of objects of the same class. You just add a function to the factory class to retrieve such objects, instead of calling the actual class of the objects your are retrieving. You can also retrieve a collection of objects related to an object right from its class, for instance retrieving children objects of given parent object. In that case you would add a function to the parent object class, despite internally Metastorage implements that using calls to the factory class, which is itself a singleton. Anyway, if you want to know more about Metastorage, you may find more information here: http://www.meta-language.net/metastorage.html There is a tutorial here: http://www.meta-language.net/metastorage-tutorial.html Some screenshots of the Web interface: http://www.meta-language.net/screenshots.html -- Regards, Manuel Lemos PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ PHP Reviews - Reviews of PHP books and other products http://www.phpclasses.org/reviews/ Metastorage - Data object relational mapping layer generator http://www.meta-language.net/metastorage.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That didn't work either. tried a few other things as well and it
looks like PHP forces you to define DOM documents in one hideous
monolithic code block without any of the encapsulation benefits
classes provide.
Not sure if this intentional due to security issues or if it's a bug.
Anyone think of a reason why it would be necessary to prohibit DOM
object embedding in a class?

[/snip] Why, at any point, would you need to get more than one customer? Good question. When I need more than one customer is when I'm displaying them all on an administration page. Maybe a better example class would be Products. One individual product is displayed on the product's detail page, but in the search results I'd normally be using the same Product class to display all the results which forces me to create a 'get_products()' method. --- The signs don't seem to show up on this reply, sorry. Anyway, I have often found the need to make an object and a collection of the same kind of objects. A Customers class containing Customer items, Products and Product. Usually, the collections all look quite the same, they have the Add (which gives me a brand new initialized item object) , Find (which returns another instance of the Customers class, this with a subset of the whole collection), Get (returns and individual item based on a key), Delete (you cannot ask an object to delete itself while you are having a reference to it), Update (call the Update method of the modified items), then, if the language allows, a means to iterate over it and posibly some sort alternatives. Beware, though, that this sounds nice and proper except when the collection starts loading and taking up memory. Then you can handle several strategies, the first is 'load as you go' or 'on demand'. If nobody asks for it, don't load it. Then, you can load the properties on demand as well. You might only load the primary keys first, to be able to enumerate them and then load the rest of the properties when the get_() function is called. Actually, from an SQL standpoint, it is better to subdivide your fields into those which are used most often, and have them loaded as a group, then several sets of specific fields, groups that usually go together (like an address record, if the street is accessed, there is a good change that the zip will also be accessed, so, load them both when either one is read. Several internal flags should keep track of which set of fields are loaded for each set. Sounds terrible? Yes, it is. It is much faster to rely on the SQL server to handle most of the job of these collections. If you are just sequentially fetching records to show on a listing, it is easier to let them come from the database, a record at a time, and send it right to the client, using and reusing the memory of the resultset over and over. Much faster than loading them in either an array or a collection and then showing them from there. Specially if using them in an environment like a web server where the connection is not persistent and whatever gets loaded in response to a page request gets lost after that is handled. They are much more usefull in batch processes, where you can hold of to that information for quite a while, and it is worth to have it handy. But we don't do that kind of processes any longer these days. Satyam One answer is that all customers or a group of customers will need to be updated/edited with the same information. Therefore you need a seperate class for multiple customers which could then be extended by group. A group of customers is a seperate object. Make sense? Well, yes I think it does, but what I'm missing is how this new object interacts with the original one if it does at all. And what would I call it? 'Multiple_Customers'? Or.. perhaps just 'Customers'! :) Do I extend the Customer class or is it a stand alone class?

From what I understand is you need a data objects class. Use a generic class such as PEAR's DB_DataObject (http://pear.php.net/package/DB_DataObject).

Re: [PHP] this may be a daft question but.....defining indexes
This may be a daft question but I keep getting notices on undefined indexes I'm sorry to tell you, but this implies bad programming-practice. ;) First off: Leveling the error_reporting in the php-ini is NOT a good idea! Have you ever tested osCommerce with error_reporting set to E_ALL? You better don't! So get used to write your applications in error_reporting E_ALL, because this will inform you of every not properly intialized var you are using. Back to the index-problem: The best way to check the indizes is: $p = isset($myArray['this_index_doesnt_even_exist']) ? $myArray['this_index_doesnt_even_exist'] : null; This will check if the index in the given array exists: If, the value will be assigned to the var $p, else null will be returned, thus $p holding null (or any other value you want to assign per default). This will prevend error-output. For more information read the isset()-entry in the official php manual. However, if you are using a third party app and want to get rid of this annoying messages, you can tell php not to output E_NOTICE or E_WARNING levelled messages. You can do this by editing the php.ini-parameter error_reporting. But basically, this is something you should never ever do. Your code should run clean even with error_reporting set to E_ALL.

Re: [PHP] Suggestions for class design
The simplest way to solve this problem is as follows:
- Have your Customer class hold only attributes for a customer. This class
would only have getter and setter methods. In the Java world, this is
referred to as a JavaBean.
- Then, have a DAO class that does your data access functions.
Here is a sample DAO class:
class CustomerDAO {
function getCustomer(..) {
...
//return a customer
}
function getCustomers(..) {
...
// return a collection of customers
}
function saveCustomer(..) {
...
}
}

Since an object should be a single instance of something (e.g. ONE

instead of using a SQL statement to return ONE customer's data I instead

The class in its current state can't handle data like that so I have to
then rethink the design and a new object variable called $customers
where I store the record set that is in return accessed directly by the
calling page itself.
With the way I'm working with these objects now they seem less like
objects and more like an organized collection of functions.
I'd appreciate some actual code recommendations as I have a hard time
understanding the abstract descriptions of how objects should work and
be designed.

Thanks for the heads up. Looks like if you define the tag like
$script= $dom-createElement('script',''); -- empty string
It tacks on an end tag.
The way that I've been doing this thus far is using XSL. If you use the
DOMDocument::loadXML() function and it has anything like that. it will
convert it to short form.
I design the back XML using Dom calls then throw a xsl at it to spit out my
page. very nice clean code that's separated from style.
So far, just playing. But ultimately I'd like to generate the whole
page using dom calls. It seems much cleaner for what I'm doing than
creating a whole bunch of large functions that do nothing more than
echo prestyled html.
Is this clean enough? :)
minimum for one of my pages that uses SQL:
?php
include(Document.php);
// a DOM Object is auto generated along with an XPath object to go with
it.
// $Document-gDom() and $Document-gXPath() to gain access to them.
$Document = new Document(rootNode);
try {
$Document-gDb()-connect(Database::SQLITE,../database.db);
} catch (DBConnectFailed $dbCF) {
die(Failed to connect to the Database.);
}
$Document-setTitle(This is the title);
// Use $Document-setStylesheet(); to set a stylesheet,
// defaults to index.xsl.
// Here is where you put the page specific code.
// XML data nodes used in the XSL template.
// This outputs the header(); and the DocType.
$Document-outputHeader();
echo $Document; // This will load the XSL document, apply it, and
return
// The page to be echo'd

[PHP] User error handler must not modify error context
Error Message:
Fatal error: User error handler must not modify error context in
[FILENAME] on line 58
This error seems to occur only when I use:
$old_error_handler = set_error_handler ('userErrorHandler');
The error number is pointing to this code:
LINE 57: global $mywebsite;
LINE 58: if ($_POST['title']) $title = $_POST['title'];
LINE 59: elseif ($_GET['title']) $title = $_GET['title'];
It's surprising how no one seem to have had this problem before. I've
googled it already and all I've come up with are the zend source
codes. I've also search the PHP mailing lists, several message
boards, etc. Nothing.
One code I've seen gave me a clue that it might have only occurred
since I'm using PHP 4.4.
My site has just been upgraded to this version. In the previous
version (4.3.11), my site works just fine. Could this be a bug? If it
is, how can I solve it at least until they've released a fixed for it?

Hello, and thanks for the reply, Tjoek -
However, this really isn't what I'm looking for. I'm simply
looking for a way to parse PHP code from within existing HTML
pages, so that I can migrate a site from Apache to IIS6.0.
Like I said, if I were using Apache, I would just add .html to my
AddType directive, and call it good. Is it not this simple under IIS?
