If you're talking about PHP 3.0 then yes. There definitely is a difference between the two loops. The for loop is less efficient. It's not because of how the grammer is written but because of the architecture of PHP 3.0.

In some benchmarking I'm doing, while() loops are a little faster than equivalent for loops.
