Simple XML variable returns "0"
- by Warren Haskins
Ok, so im working with tumblr's API and im using SimpleXMLElement with php and ive run into a problem.
Basically, when I call on a variable it just prints a zero.
for instance :
<?php echo $data->posts->post[0]->photo-url[5]; ?>
This just breaks the page, and when I leave out the [5] it just prints zero
I want to echo the photo-url with the number [5] but I cant get my head around this and its killing me. I just dont understand why it wont work.
Heres a sample of the simpleXMLElement print-out :
SimpleXMLElement Object
