I said this above as well but, the non-defined "$first" was completely my fault. I was trying to clarify the code a bit once I had put it on the site and then ended up forgetting to change the other one. The input looks like this- 

1424621700, 2015-02-22 16:15:00, 4294.700
1424621760, 2015-02-22 16:16:00, 4289.700
1424621820, 2015-02-22 16:17:00, 4299.800
1424621880, 2015-02-22 16:18:00, 4302.800
1424621940, 2015-02-22 16:19:00, 4296.900
1424622000, 2015-02-22 16:20:00, 4301.000

And I'm trying to get the value "1424621700" returned after the file is split at the commas.
