while loop

[AV1611]

Is this valid syntax, or do I need to add "DO {"

[code]

while ($i <= 998)
        {
                 // Do some stuff here
        }


// or do I do this


while ($i <= 998)
        {
            do{
                        //Do some stuff here
                        }
        }

// Or are they identical??????????????
[/code]

Your first attempt is valid.

Please disreguard my question, I was obviously out of my mind when I asked that...

There is two type of while loop do-while loop and while loop they are same apart from do-while is like this:
[code]do {


}
while($i <= 998);[/code]
I prefer to use just while whithout the do bit.

Esentually a [i]while[/i] loop is different from a [i]do while[/i].

With a while() your expression is evaluated before each iteration of the loop, do while evaluates the expressions after each iteration.

Thanks you... that mean the while exit is determined by the clause, and the do is determined by some other criteria...

that is very usefull information... I always wondered if there was a difference...

Thank
