Thank you for getting back to me, your the first.
The array works fine – I have tested it using var_dump().
Attached are the two files – xml.test – this holds the array of the text blocks which is being parsed by image.php.
Line 38 is the problem, if you comment around the foreach() statement and un-comment the commented lines you should see it working fine, its when its within the foreach statement when it errors.
Regards,
James

what does paramter 2 contain in each case? var_dump(), print_r(), echo ?!?

try var_dump($text); or print_r($text); to see what you have
(if its an XML node object - dump $fontsize, $fontxpos instead!!!)
