Well in the process of answering this question I pretty much did your homework for you. But you should pretend that I have not and I am going to forget about that as well and just focus on what you have asked.
Also, PHP_SELF by itself means nothing. $_SERVER['PHP_SELF'] which is what you are most likely referring to pretty much points to the page itself that you are writing code in. You make it seem as if there is something that is going to help you to make tic-tac-toe but I do not think so. Maybe you can correct me if I am wrong.
You seem to mention that you already have an interface that you are working with. I do not have the code for this interface so I am going to assume that it looks something like this:
http://jsfiddle.net/vyyXP/1/
the form html tag usually contains another attribute called action. You usually use this if you want the data from the form to go to some other page. Since we don't want to create another page we can either omit this altogether or use something like:
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"></form>
This is the only place your PHP_SELF comes in. Again, if you know something else about it, let me know.
So.. now lets actually start solving this problem of yours now.
Step 1: Figure out how to get and use the button clicks.
Every time you click a button. The form submits and the page reloaded. If you have knowledge about headers, it'll add an extra pressed=1 or pressed=2, etc every time you click a button and submit the form. This 'pressed' keyword comes from the fact that our buttons have name="pressed" as an attribute. (Notice that all buttons have the same name!).
We will need to use this data and figure out what the person actually clicked.
Since I'm using <form method="post"> you can get this data by using <?php $pressed = $_POST['pressed'] ?> alternatively if you used method="get" you would have had to use $_GET['pressed'] instead.
As an exercise just display an 'X' on whichever button the user clicks on. You should dynamically generate the html code for the buttons inside the form to make your life easier.
<?php
for ($i=0; $i<9; $i++) {
echo '<button name="pressed" value="'.$i.'">';
if ($_POST['pressed']==$i)
echo 'X';
echo '</button>';
if ($i!=0 && ($i+1)%3==0)
echo "</br>\n";
}
?>
Step 2: Figure out how to remember data.
Since you're using php. I'd recommend that you use php sessions. You basically just need to put session_start() in the beginning of the file and then you can store values into the $_SESSION variable and php will remember then next time you visited the page. You can use this to count how many times a button has been pressed so that you can alternate between O's and X's.
Figure out how to destroy sessions. (Make that reset button work). This is pretty important.
You can also use cookies or write to a file if you want but sessions are probably easiest thing to use.
Here is an example of a simple counter.
<?php
session_start();
$count = 0;
if (isset($_SESSION['count']))
$count = $_SESSION['count'];
echo $count;
$_SESSION['count'] = $count+1;
?>
And.. you're done!
This is probably everything important that you need to do. The rest is just implementing how the game tic-tac-toe works. Let me know if you need any clarifications on anything I have written or if you need more information. Hope this helps!
