PHP只有Hit Counter？

Question

So, I used to play with web development many years ago, and I'm a little rusty, but not THAT rusty!

I just made a full fledge video game page the other day using PHP variables to load different games into different size iframes. With that said, why on Earth can I not get a simple PHP hit counter to work? I have downloaded script after script after script, CHMOD'ed the txt file to 777, the whole 9. Does Chrome not support hit counters or something? It seems even the sites I visit that offer hit counters through them don't work on their demo pages!! What is the deal? I remember years ago, I copied about 10 very basic lines of code, saved it as a PHP file, uploaded it along with a blank txt file to a server, and bam, worked perfectly everytime. What has changed?

Here's the code I'm using. By the way. I tried adding this into my index.html, I also tried using it as a separate php file and calling on it with INCLUDE, everything. Nothing seems to work.

<?php

$open = fopen(“hits.txt”, “r+”);
$value = fgets($open);
$close = fclose($open);

$value++;

$open = fopen(“hits.txt”, “w+”);
fwrite($open, $value); // variable is not restated, bug fixed.
$close = fclose($open);

?>

and then where I want the results to be displayed, I have,

<?php echo $value; ?>

Any ideas?

You can use the following as a basic hit counter:

<?php
    $counter = file_get_contents('./file') + 1;
    file_put_contents('./file', $counter);
?>

You may want to implement some way of checking that it's not just one user refreshing the page... Something simple like:

<?php
    session_start();
    if(empty($_SESSION['visited']){
        $counter = file_get_contents('./file') + 1;
        file_put_contents('./file', $counter);
    }
    $_SESSION['visited'] = TRUE;
?>

Will check if the user has already visited the site in the same session and not increment the value if they have.
