IIS5 error problems

[oakavenue]

I am redeveloping a website that ran on Linux without errors.
I am running IIS5 and keep on getting errors with variables.
ie. with an if statement it says that the variable is undefined.
Can anybody help me.

😕

Perhaps the error reporting level was different on the linux box, that's why you weren't seeing them.
In PHP variable declaration is not mandatory, but it can throw a NOTICE if error reporting is set at E_ALL in your php.ini
Personally I prefer to declare all my variables before use
