In the Do while loop Can we only use the addition or subtraction operation ?

I tried to to multiplication but it either shows the same number in each line. Somebody please explain. <?php $i = 5; do { echo "The number is " . $i . "<br/>"; $i * 2; } while($i <= 100); ?>

You can do all kinds of operations. Please show your code for specific help https://www.sololearn.com/discuss/1316935/?ref=app

Now, since you have updated with code: You only did multiplication but did not assign it to the variable i again. Use this instead $i = $i * 2;

You want to change `$i * 2;` to `$i = $i * 2` or `$i *= 2`.

I think you can do everything that is possible outside the loop...
