Hi,

I am trying to create a PHP counter, I think I know how to gather the information about the user, but I can't figure out what to do next. Let's say I have ther IP address, and the time and date.
How can I use that to save the information and display it on their screen?

any help would be appreciated..

thanks.

Do you wana do that for all the viewers? If so, why do you wana save it at all?!

Anyway, here's a simple counter :

<?PHP
$fileName = "counter.txt";

# If you use "a+" or "a" in fopen, you can not fseek it
# backward! It puts the fp at the end of the file and
# you can not go back! Beware!!!
if ( file_exists( $fileName) )
$fp = fopen( getcwd() . '/' . $fileName, "r+");
else
$fp = fopen( getcwd() . '/' . $fileName, "w+");
$currNum = ( $oNum = fgets($fp) ) ? ( $oNum ) : ( 0 );
$currNum++;

# You can use fseek($fp, 0); insetead of rewind in here!
rewind($fp);

fwrite( $fp, $currNum);
fclose($fp);
echo $currNum;

?>

PS: You can use "print" or "echo" to output something, you can even write it as inline php, like:

<body>
<h1> <?php print "hello!" ?> <h1>
.
.
</body

or just simply :

<body>
<h1> <?= "hello!" ?> <h1>
.
.
</body

Note: You should check your php.ini file and make sure that support for short tags ( i.e. <? instead of <?php ) is on, I can't remember it's name at the moment!
