'PHP only Hit Counter?

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:

$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:

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.

You can create an ajax file in PHP and call ajax in a time interval and display hit counter to page.

For this first of all create an ajax file: ajax_user_count.php

<?php
session_start();
$log_file_name = 'traffic_count.log';
$count = file_get_contents($log_file_name, true);
if(empty($count)){$count = 0;}  
if(isset($_POST['action'])){
    $action = $_POST['action'];
    if($action == 'enter'){
        if(!isset($_SESSION['user_count'])){
            $count += 1;
            if($count == 0) { $count = 1; }
            $_SESSION['user_count'] = $count;
            $message = $count; 
            file_put_contents($log_file_name, $message);        
        }
    } else if($action == 'leave'){
        $count -= 1;
        $_SESSION['user_count'] = $count;
        $message = $count; 
        file_put_contents($log_file_name, $message);
        session_destroy();  
    }
}

echo $count;
die;

Then call the ajax file by this

$(document).ready(function(){
    get_enter_web_traffic();
    setInterval(function(){ 
        get_enter_web_traffic();
    }, 1000);
    $(window).bind("beforeunload", function() {
        $.ajax({
                type: "POST",
                async: false,
                cache: false,
                url: "ajax_user_count.php",
                data: {'action' : 'leave'},
                success: function(result) { },
                error: function(data) { location.reload(); 
            }
        });
    });     

});

function get_enter_web_traffic(){
    var data = {'action' : 'enter'};    
    $.post('ajax_user_count.php',data,function(response){
        $('#count_user').html(response); // website hit count
    }); 
}

I am learning PHP currently. Came up with this easy to implement hit counter. Check it out

<?php 

$filename = "count.txt";// the text file to store count
// Open the file foe reading current count
$fp = fopen($filename, 'r');

//Get exiting count
$count = fread($fp, filesize($filename));

//close file
fclose($fp);

//Add 1 to the existing count
$count = $count +1;

//Display the number of hits
echo "<p>Total amount of Hits:" . $count. "</p>";

//Reopen to modify content
$fp = fopen($filename, 'w');

//write the new count to file
fwrite($fp, $count);

//close file
fclose($fp);

?>

Hope this piece of code comes in handy for someone.

file_put_contents('count.txt',"\n",FILE_APPEND|LOCK_EX);
$count = filesize("count.txt");

It appends one byte to a file and read the file size as the counter. it is the fastest and error free logic i found with 0.1 ms

This counts initial hits (not refreshes) and saves to a json file by date:

<?php

$pageWasRefreshed = isset($_SERVER['HTTP_CACHE_CONTROL']) && $_SERVER['HTTP_CACHE_CONTROL'] === 'max-age=0';
if (!$pageWasRefreshed) { #ignore page refresh
    $today = date("Y/m/d");
    $filename = 'traffic.json';
    $traffic = json_decode(file_get_contents($filename), true);
    $traffic[$today] += 1;
    file_put_contents($filename, json_encode($traffic));    
}

?>

The refresh checker is from PHP: Detect Page Refresh
