Add a try/catch block inside the loop.

hi @niche im not that much familir with php error handling.can you direct me to proper example which is using try/catch within while loop? – DAM_86 May 23 '13 at 03:55
[Here](http://stackoverflow.com/questions/141560/should-try-catch-go-inside-or-outside-a-loop)'s a link to another thread related to your question. In your case, I'd put the try/catch block *inside* the loop because you're trying to output the result of the iteration through the IPs. – Niche May 23 '13 at 03:58
