"PHP for incrementing a variable please."

I'd look it up myself, but you people are so much help :D

PS, I'll show you why this afternoon sometime!

$var++ will increment a variable.

$var = 2;
echo $var++; // prints 2

$var = 2;
echo ++$var; // prints 3

$var = 2;
echo $var--; // prints 2

$var = 2;
echo --$var; // prints 1
?>

Any questions?

Hmm, it;s not working. I know PHP pretty well and how to set up permissions and stuff, yet this is still eluding me.

Cheers - it's for my new and improved chat room! I deleted the code that did the increment bit and couldn't remember how to do it.

First, create a blank file. Name it counterlog.txt

Then create a new file. Copy/paste this into it.

$viewss = file("counterlog.txt");
$views = $viewss[0]; $views++;
$fp = fopen("counterlog.txt", "w");
fwrite($fp, $views);
fclose($fp);
print $views;
?>


Save it as counter.php. Then you use include to get the code on whichever page you want.

include ("counter.php");
?>



Upload the files and chomod counterlog.txt to 766, and you should have a brand new counter

If you ever want to change the number of visitors (You evil cheater :P), open counterlog.txt, and edit the number to what you want. Remember to chmod it again when you're finished.

I hope this is what you were after?
