[Xerte] Function split() is deprecated

[Simon Barne]

Dear Xertists

I am getting this message above some of my templates:

Deprecated: Function split() is deprecated in
/home/intouea8/public_html/xerte/modules/xerte/play.php on line 17

For example, here:
http://intouea.com/learn/english/vocabulary/elementary-pre-intermediate/relatives/

The line in question is:

$dimension = split("~",get_template_screen_size($row_play['template_name'],$row_play['template_framework']));

Any ideas?

Many thanks,

Simon
