adding using $i++

[anfetienne]

i didnt know what to call this. but yeah lol

if $i = 0 and somewhere in my code i use $i++ will $i start at 0 or 1?

if it starts at 1 can i set $i = -1 so when it starts counting it starts at 0?

@anfetienne
It's pretty simple, $i starts from whatever you set it in the beginning... using $i++ is the same as doing $i = $i + 1;

or putting it in other words:
$i++ post increment
++$i pre increment

ok thanks....i've fixed it....

i had two $i on my page and it was messing with my loop so it always started from 1....i've changed one of them and its output starts at 0 like it should

@Dormilich
To expand a little on that: the post-increment will assign the current value of the right hand variable* to the left hand variable*, and then increment the right hand variable's value; the pre-increment operator will do the opposite: increment the right hand, and then assign that to the left hand.

*Variables is just an example - it can be other things, such as an expression.

Don't forget decrement!
$i--
--$i


And multiplication
$i**
Division
**$i

Yes that last two are a joke

@dlite922
Damn you! I thought you were serious about the last two, and I was about to reach for the manual to learn something new! :P

Hey it would have been great, if $i** does $i*$i(Now it wont do ofcourse).

We could easily multiply a number by itself..

@dheerajjoshim
Bet you've already tried that one... :)

[Dheeraj Joshi]

Nop... Never tried it..
