So why is he typing <li>. I know what it is but wouldn't it print 11 22 33 44 55 66, etc since he is adding a list?

I don't have a solid understanding why it is not print 1.1 2.2 3.4 like a normal list with strings so like 1. hi 2. bill 3. cat...just like a list, and the counter ( being increased increments) instead of words.

I think you're thinking of an ordered list - where the list items are prefixed by numbers by default.

<ol>
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
</ol>

Will create something like this

  1. Item 1
  2. Item 2
  3. Item 3

Using an <ol> or <ul> with list-style-type: none; will hide the leading character - but you can also set numbers on <ul> and discs on <ol> by playing setting the characters using list-style-type.

There is some css styling on the page that probably has list-item-style: none would be my guess.

thanx kevin! I took html and CSS on codecadmey so I can see where ur coming from, that had me puzzled. So could you just not type the unordered list and list and just type $counter there and have it show its numbers? If not would you have to var_dump it?

You could do

<?php
echo $counter;

and you would get 0123456789

or you could

<?php
var_dump($counter);

and you would get int(0) int(1) int(2) int(3) int(4) int(5) int(6) int(7) int(8) int(9)

Awesome! That's what I was guessing would be the other option.

You can do whatever you pretty much want to (that's valid) inside of the loop. Just whatever is in the loop will be executed each time the loop goes.
