Reference — What does this symbol mean in PHP?
...it is faster. $i++ would have the same results.
Pre-increment is a little bit faster because it really increments the variable and after that 'returns' the result. Post-increment creates a special variable, copies there the value of the first variable and only after the first variable is used, repl...
Why do stacks typically grow downwards?
...ection strategy story. Makes some sense that text segments are laid out growing upwards-- programmers of yore had somewhat more direct contact with dealing with the implications of that than the stack.Thanks paxdiablo.

So CPU manufacturers took a shortcut. They use an instruction set which allows a full 6...
