Hello,
I just have a question, often there are 'optional' parameters to functions, I've always thought that most of the time I could pass null to these if I wanted to leave one empty. This has as far as I can tell always worked except recently I was using substr(). If I pass null to the third param, I get nothing back. Isn't passing null the same as not passing anything? Is this a bug? Or is my logic flawed?
