[SOLVED] Converting XML Object to String

[Psycho]

I am converting an XML file into an object via

 

$xml_data = simplexml_load_file('xmldata\test.xml');

 

However I run into a problem if I try to use a value within that XML object as a string:

 

<?php

$id = $xml_data->id;
$array[$id]['keyname'] = $xml_data->keyname;

?>

 

Results in the error Warning: "Warning Illegal offset type in C:\xampp\htdocs_dvd\xml.php on line 120"

 

I can avoid the error by enclosing the value in quotes when assigning to a variable such as this:

 

<?php

$id = "$xml_data->id";
$array[$id]['keyname'] = $xml_data->keyname;

?>

 

Is this the best approach?

or you can cast it as string

 

$id = (string)$xml_data->id;

Ok, thanks. That will help whenever I have to go back and edit the code as it will be more apparent what is happening. If I was to use just double quotes I might see that later and think I don't need them.
