while loop with variables? 1234

Question

I tried to create a while loop.

<div>
    <?php
        while($i < 100){
            echo $i + 100
            $i++;

            if($i = 23){
                echo 'reached!';
            }
        }
    ?>
</div>

But I just get errors. What did i make wrong?

Thank you!

When posting a question asking about errors its always a good idea to include the errors in the post. — Jite, Oct 18 '15 at 12:47

There's a difference between = and ==. And you're using the wrong one — Reeno, Oct 18 '15 at 14:03

Thats not hard to fix.

You can get the mistake from the errors.

you forgot a ";" after the echo $i + 100
if ($i = 23) have to be if($i == 23)

So finaly it looks like:

<?php
     while($i < 100){
         echo $i + 100;
         $i++;

         if($i == 23){
             echo 'reached!';
         }
     }
 ?>

Try to add ; after echo $i + 100 :

echo $i + 100;
