Return with no value or return FALSE ?

[terryds]

What's the difference between returning null (with no value) or return FALSE ?

 

I'm a bit confused about which to choose...

 

Can you give me the implementation of those two and explain the essential to me?

"false" is a value. It's a boolean value indicating that a condition is false. If you're not planning to do anything with the return value of the function there's no different between null, false, "n" or 5.

 

A function might return false if something didn't work properly and other values if it did work. You return null if you don't expect the function to return anything the developer wants.
