Hello everyone.
The following is an extract of a routine returning error messages
from a
xml file:
function title($index)
{
$xml = simplexml_load_file("lingo.xml");
return $xml->message[$index];
}
The problem is that if I call the routine with a value [ex.
title(6)] I
receive the message, whereas if I call the routine with a variable
[ex.
title($value) where $value=6] there is no way I can receive the
message.
I tried in many different ways but it looks like it's a bug of
simple_xml.
This isn't too helpful, but I'm 99.94% it's something in your code.
Simplify your code until you find the shortest piece that works and
then add
back lines until you find your error.

Thank you for coming to help.
That's what I did.
The routine can't get shorter than that. I attach now the xml file
(shortest version). Just to be clear:
<?xml version="1.0" encoding="utf-8"?>
<messages>
<message id="0">About us</message>
<message id="1">Nothing has been ordered!</message>
<message id="2">Continue shopping</message>
<message id="3">Shopping cart</message>
<message id="4">Contact us</message>
<message id="5">News</message>
<message id="6">Welcome</message>
</messages>
Am I referencing the nodes incorrectly?
Thank you

How about the full script as you don't include how/what you are passing
to the title function.

Ok. I made a mistake.
I forgot to mention that the variable used for calling the function
title comes from an INPUT tag of a form. Ex:
<?php
function title( $index )
{
$xml = simplexml_load_file( 'lingo.xml' ) ;
return $xml->message[$index] ;
}
$param = $_POST['msgs'] ; //'msgs' coming from an INPUT tag of a form
$value = title( $param ) ;
echo( $value ) ;
?>
While before the function returns the message stored in the xml file,
now it return no value.
Any idea why?
Cast it to a int otherwise $param is being set as a string which then
causes simplexml to look for attributes by name on the first message
element.
