Undefined Offset

Once again, as I look at my error_logs, I see another page that has a few errors.

 

[root@ohx-lw-tanager httpd]# tail -f error_log

I am not sure why this is acting this way. I have hightlighted the areas in the code that the error log is point to. 

 

This wasnt an issue before, but now is.  Can anyone point out my issue?

 

Thanks!

This means that the array has only one index and the script is trying to access the second index (which doesn't exist). Keep in mind, the count starts at 0 (zero)
