I think that is about the useless comment "set i to 0"...
for my experience, now I feel by not stuff all parameters in function declarations in one line can sometimes offer better readability, like this:
PHP Code:
int
MyFunc(
int iParameter1,
float flParameter2
)
looks better than:
PHP Code:
int MyFunc(int iParameter1, float flParameter2)
... especially when there are too many parameters
