while loop question....

[Tim Mousel]

Hi,

I have a question about a while loop:

echo "$number is number<BR>";

$t = 0;
while ($t <= "$number") {
$estimate[$t] = ($width[$t] + $length[$t]);
echo "<BR>$estimate[$t] is estimate $t<BR>";
$t++;
} 

If $number is set to 4 I get the following for my output:

4 is number

18 is estimate 0

12 is estimate 1

24 is estimate 2

24 is estimate 3

0 is estimate 4


How do I change my code to make it say:

4 is number

18 is estimate 1

12 is estimate 2

24 is estimate 3

24 is estimate 4

//0 is estimate 4


Thanks!

Would this work?

echo "$number is number<BR>";

$t = 0;
while ($t <= "$number") {
$estimate[$t] = ($width[$t] + $length[$t]);
$temp = $t + 1;
echo "<BR>$estimate[$t] is estimate $temp<BR>";
$t++;
}

Hi,

Partially, here's the result:

4 is number

18 is estimate 1

132 is estimate 2

48 is estimate 3

60 is estimate 4

0 is estimate 5

It's showing 0 for estimate 5 when there is no number 5.

Any other solutions?

I've got it working...I changed it to a for loop:

echo "$number is number<BR>";

for($t=0; $t<= ($number - 1); $t++) {
$estimate[$t] = ($width[$t] + $length[$t]);
$temp = $t + 1;
echo "<BR>$estimate[$t] is estimate $temp<BR>";
} 

If there's a better way of doing this, please let me know.

Thanks,

Tim

You can also remove the = from the while loop.

echo "$number is number<BR>";

$t = 0;
while ($t < "$number") {
$estimate[$t] = ($width[$t] + $length[$t]);
$temp = $t + 1;
echo "<BR>$estimate[$t] is estimate $temp<BR>";
$t++;
}

um.. that was for less than or equal to. the way he did it before was the correct way. your for loop is..

4 is number

0 is estimate 1

0 is estimate 2

0 is estimate 3

0 is estimate 4
