#5 checking array for daycast

[Anonymous]

More of a php question, probably...

Winston-Salem (or KINT) rarely if ever has daycast info. So, when using the sample code to get daycasts, an error is generated:

Warning: Invalid argument supplied for foreach() in /pxweather/test.php

Seems like there would be a way to check if the array includes the daycast before launching into the foreach function. Unfortunately I'm a php newbie -- although I've tried to program a check, nothing seems to work. I've tried array_key_exists and isset, but can't seem to get them to do what's needed.

Any advice?

Other than this programming problem on my end, I've found pxweather very useful.
