Can you explain this?

[|2eM!x]

Okay, i found this good php script:

<?php
$countfilename = "VisitorCount.txt";
$whattoread = @fopen($countfilename, "r") or die("Error opening count file");
$contents = fread($whattoread, filesize($countfilename));
fclose($whattoread);

$contents = ($contents + 1);

$whattoread = @fopen($countfilename, "w") or die("Error opening count file1");
@fwrite($whattoread, $contents) or die("Error with addition");

fclose($whattoread);
echo $contents;
?>

works like a charm..great job..what im wondering is if i can have an explanation for what it all does?

you dont have to explain like in depth, just like $countfilename, and all those and there arguments...anything you see fit..

thanks alot


**edit
im beginning to understand alot, this isnt so hard, at all!!

heres what ive figured out in the last 5 minutes:

Everything with a $ is a string, not a fixed variable(what i mean is, to open a file i dont have to type $whattoread =, it can be $readfile =

$whattoread = @fopen($filename, "r") or die("Error opening count file");
means that it should "r"ead the file, on error say ("Error opening count file")--dont really understand what die does though

and that you can add to strings: echo $contents, " Visitors"

other help = good
