Aurelian,

This is simpler using a for loop, but if you need to use a while loop:

$number = 10;

while ( $number >= 0) { 
    echo "$number "; 
    $number--; 
}

Or, better:

for ($number = 10; $number >= 0; $number--)
{
  echo $number; 
}

Change your $number <= 10 to $number >= 0. That should fix everything.

Ricky, that just recreates the problem in reverse--it doesn't stop at 10 (unless he doesn't need to stop at 10, I suppose).

He needs to stop at 0 not 10. He is trying to count down but his while check is prepared for counting up.

Aurelian,

You could use an AND statement ("while $number is <= 10 AND > 0) or you could increment (++) rather than decrement, and change your variable to start at zero. Or, you could change your while's condition.

Yes but the problem is that i want to start from 10 and stop at 0 . It goes infinity when i run that code. If i put ++ and i start at 0 , it will go from 0 till 10 but i want to go from 10 to 0 and stop . And whatever else i do , the code crash.

Im waiting for PHP Basics and well, cant wait for them , in case they come up in a month , ill learn PHP basics faster than they come out xd so ill be one month ahead.
