未定义的偏移量：抛出3个错误但未显示错误位置

Question

i am getting this error Undefined offset: 3

in brief the message is like this,

Internal Server Error
Undefined offset: 3

An internal error occurred while the Web server was processing your request. Please contact the webmaster to report this problem.

Thank you. 

I would like to know from where does it happen or how to see the exact location of this issue so that i can easily go and resolve it. i am using Yii framework but sadly it doesnt display me from where this error occurs.

Do i need to have php error logs enabled to see this ?

Answer 1

Internal Server Error basically occurs on the server connection. And this seems some of the input missing to complete your functionality.

Basic i dont have idea on your code and functionality. So you are the person working on the functionality. You need to check the last functionality you worked in this.

Better to do the step by step debug process to resolve this.
