He is initializing array members to an empty value?
I cannot see, whats wrong with it.
Ok, this could all be in the first line, but thats personal style, isnt it?

This is probably a typo and the ['all'] is missing. 

I why all this?
Perhaps to avoid nasty php notice warnings in the log file when accessing
undefined array members:

The original code seems a bit stupid, but its not.
