I am developing an application that reads a csv file and generates a report. It is working properly. However, when I run my application in Eclipse IDE, I see messages on the console that I am not sure if it is a problem or not.
I tried to use isset to fix the uninitialized variables and functions, but it did not solved my problem. My question is: Should I worried about these messages? If, yes, how could I solve it? If I tried to run my application on a Unix server, I will a problem? I am having a hard time to interpret those messages.
