PHP4 -> PHP5 issue

[Mathieu Maes]

Hi there

I'm quite experienced in programming in PHP4, but I would like to make
a step to PHP5.
I created following class which works perfectly in PHP4 :

Class Nessi
{
// ident part
var $user = ""; //the username
var $password = ""; //the password
 
// invoice records
var $invoices = array(); //list of invoice records
var $i = -1; //invoice counter
 
// client records
var $clients = array(); //list of client records
var $j = -1; //client counter
 
var $XML = ""; // The XML file content
function OpenFile($filename)
{
// leest de inhoud van een bestand naar een string
$handle = fopen ($filename, "r");
$contents = fread ($handle, filesize ($filename));
fclose ($handle);
$this->XML = $contents;
$this->ParseXML();
}
 
function ParseXML()
{
$doc = xmldoc($this->XML);
$root = $doc->root();
$children = $root->children();
 
foreach($children as $child)
{
if ($child->type == "1")
{
switch ($child->tagname)
{
case "ident":
$this->Ident($child);
break;
case "invoice":
$this->Invoice($child);
break;
case "client":
$this->Client($child);
break;
default: ;
} // switch
}
}
unset($this->XML);
}
 
function Ident($child)
{
$record = $child->children();
 
foreach($record as $item)
{
if ($item->type == "1")
{
if ($item->tagname == "user")
{
$content = $item->children();
$this->user = $content[0]->content;
}
if ($item->tagname == "pass")
{
$content = $item->children();
$this->password = $content[0]->content;
}
}
}
}
 
function Invoice($child)
{
$i = 0;
$this->invoices[++$this->i] = array();
$invoice = $child->children();
foreach($invoice as $invitem)
{
switch ($invitem->tagname)
{
case "header":
$header = $invitem->children();
foreach($header as $headitem)
{
switch ($headitem->tagname)
{
case "clientid" :
$text = $headitem->children();
$this->invoices[$this->i]['clientid'] =
$text[0]->content;
break;
case "clientinfo":
$text = $headitem->children();
$this->invoices[$this->i]['clientinfo']
= $text[0]->content;
break;
case "date":
$text = $headitem->children();
$this->invoices[$this->i]['date'] =
$text[0]->content;
break;
default: ;
} // switch
}
 
break;
case "items":
$items = $invitem->children();
foreach($items as $item)
{
if ($item->type == "1")
{
if ($item->tagname == "item")
{
$content = $item->children();
$newitem['desc'] =
$content[0]->content;
$newitem['price'] =
$item->get_attribute("price");
 
$this->invoices[$this->i]['items'][$i++] = $newitem;
unset($newitem);
}
}
}
break;
default: ;
} // switch
}
}
function Client($child)
{
// not yet implemented...
}
}
 

If I include this class into a script running in PHP5, I only get a
blank output. In fact, the execution seems to stop when including or
instantiating this class. I don't get any error message, even with
error_reporting (E_ALL).

What am I missing ?

I didn't really looked into your code but usually the biggest difference
between objects in php4 and php5 is that all the object variables are
passed by reference in php5 (and I think I've seen you use some of those :)

Is there something in an errorlog (if that is turned on in php.ini)?

all errors are usually logged in a file as well... Nothing in there.

This is the script how I use the class :
=======
<pre>
<?php
require "nessi.class.ph p";
$xml = new Nessi;
$xml = loadfile(invoic e.xml);
print_r($GLOBAL S);
?>
</pre>
=======

The output of the script is :
<pre>
I really haven't got a clue ...

[Dikkie Dik]

Does the nessi class code start with <?php ? It may start with <? while
short tags are not configured in php.ini

To instantiate the class Nessi I think it should look like this:
$xml = new Nessi();

>$xml = loadfile(invoic e.xml);
print_r($GLOBA LS);
?>

I think this is a server configuration problem.

I usually use <?php ?>, but now I tried with <? ?>. Now the code is
just shown in the output in stead of parsed...

Thanks for all your efforts !

This generally means you have an error in the required file
(nessi.class.ph p).

Ensure you have all errors enabled and displayed, or check your error
log (often times the server error log) for errors.

I suspect you'll find an error in the class file.
