Question

Simple question:

Why is this:

 for($k=1;$k<=10;$k+2) { }

giving an infinite loop? When I change $k+2 by $k++, it works fine.

How can I correct it? (I can’t change the 10 for an impair number because I need this function to work either with a pair or impair value at that place)

Answer 1

$k+2

This won’t change $k‘s value, so it never get’s higher than 10. Probably you meant:

$k+=2

Which will increase $k by two each time the expression get’s evaluated (at the end of each for-loop).
