B) 1 + 1 / 2
Should there be spaces?
What is considered standard, with or without spaces?

Whitespace is irrelevant in PHP. They'll both evaluate the same.

I would use spaces, myself, just for readability. That's the only difference: A string of numbers and operators with no whitespace is hard to read. There's no standards preference here.
