PHP - Moved: Get Unique Visitors

Hi, I want to show one image for the new visitors of my website and another for the returning visitors. What I want to do is that after the visitor reload the page he will see another image instead of the first one.  

Hello to all!   I ask myself the following question: Is there a way that is better to calculate the number of members / guests online 

Hello PHPers,

One more help I think may be wrong.  I currently have code as $_GET['width'] . "x" . $_GET['height'];.  This provides continually with 640 * 480. 

 believe this to be incorrect as I do not think that everyones screen is set to this.  Neither is my screen resolution and is still capturing these figures.

Is there something wrong with the variable that should be changed so that it can pick up the visitors screen resolution.
Thank you kindly,
HJ

I'm assuming this has something to do with cookies, which I am not to familiar with as I am pretty new to this PHP world and have mostly worked with wordpress... but this question was brought up to me, and I don't know where to start.

If a user is signed up for the mailing list on a site, we would like the home page the user lands on to be different than the page a new visitor who isn't signed up for the mailing list would see. I have tried to google this, but maybe I am using the wrong choices of words?

Any advice, links, etc would be so so soooo appreciated.   

Thanks
V

Hello

How do I fetch a current visitors ip address, and turn it into a variable?

The visitor should only be able to enter the same form once, so I want to compare the current visitor ip address with ip addresses in the database to achieve this.

Best regards Morris

Can you see any problems with the code below? It doesn't work.

What I am trying to do is quite straightforward.

The links on my site look like this:

go.php?id=1&url=usa
go.php?id=1&url=uk
go.php?id=2&url=usa
go.php?id=2&url=uk

When a visitor clicks on one of these links, I want to grab the values of the id and url parameters, count the click, and redirect the visitor.

Here's the error that I get when I try the code:

Hello, I have some questions about dates/time ...

I have a site where registered users will receive messages, I want to include the date/time with that message.
I am not sure what is best way to do this, so I am recording the GMT hours offset from users input (from receivers), but then I saw that the hours offset from the GMT is different in different seasons of the year, so how do I detect correct local time for the message receiver? Is it something like a database with start-end time of daylight savings hour adjustment or how is this done?

i want to make virtual money (credits, tokens) whatever you want to call it but make no mistake this is not for profit at this point but i like the concept of visitors having something to do with other members of site for example to kill bordom and create a reason to play games, compete in competetions, it will have to conversion to real money at this point but i wish to do this script using php and mysql and have very basic coding skills in these areas anyone please help me make this script...


reply and let me know if you like this idea


please help me as this is achievable as fb has it and more sites are moving toward these same ideas, even tho fb is real money it is more to do with fun at this point until we do this stage another stage canot proceed it.

Nothing fancy, I am just looking for a simple php script that would check a text file on my server that has a bunch of domains in it. I want the script to ping a random 5 or 10 sites in the list, and then redirects the visitor to the fastest one, or at least one that responds, and is not down. If all that are checked are down, then it would need to recheck the list.

I want it to pick random domains out of the list, as I don't want users directed to the same site(s) all the time, just because it pings the best.

When I say ping, I am talking about making sure the user isn't directed to a website that is down, or a slow loading website. I am not sure if "ping" is the correct word for that tho?

Can anybody offer me code like this for free, or is this type of request getting into something that would need to be paid code? (and if so, any idea how much? I didn't post this in the freelancing forum, because it sounds like it might be something simple to code.

I am not a coder, so I am looking for something complete that I can add to a php file and it works.

Thanks for any code, pointers/problems with this idea, or price quotes (if necessary) on this little script I am looking for.

How do you have a log generate two different logs, and having where it posts the log at, depend on if it's a visitor, or a search engine spider HTTP_USER_AGENT (Like Googlebot, Msnbot, Yahoo! Slurp.)

<?php
    define("DATE_FORMAT","m-d-Y - H:i:s");
    define("LOG_FILE","/full_path/visitors.html");
    define("LOG_FILE2","/full_path/search_engine_bots.html");

    $logfileHeader='DATE - IP - HOSTNAME - BROWSER - URI - REFERRER'."\n";

    $userAgent = (isset($_SERVER['HTTP_USER_AGENT']) && ($_SERVER['HTTP_USER_AGENT'] != "")) ? $_SERVER['HTTP_USER_AGENT'] : "Unknown";
    $userIp    = (isset($_SERVER['REMOTE_ADDR'])     && ($_SERVER['REMOTE_ADDR'] != ""))     ? $_SERVER['REMOTE_ADDR']     : "Unknown";
    $refferer  = (isset($_SERVER['HTTP_REFERER'])    && ($_SERVER['HTTP_REFERER'] != ""))    ? $_SERVER['HTTP_REFERER']    : "Unknown";
    $uri       = (isset($_SERVER['REQUEST_URI'])     && ($_SERVER['REQUEST_URI'] != ""))     ? $_SERVER['REQUEST_URI']     : "Unknown";

    $hostName   = gethostbyaddr($userIp);
    $actualTime = date(DATE_FORMAT);

    $logEntry = "$actualTime - $userIp - $hostName - $userAgent - $uri - $refferer<BR>\n";

    if (!file_exists(LOG_FILE)) {
        $logFile = fopen(LOG_FILE,"w");
        fwrite($logFile, $logfileHeader);
    }
    else {
        $logFile = fopen(LOG_FILE,"a");
    }

    fwrite($logFile,$logEntry);
    fclose($logFile);
?>

PLease help me PHP friends to correct my codes.

hi, im trying to create a website and only now started thinking about the security part(noob mistake). say for example i have home.php page and an index.php page. index.php is where users would sign up/log in. the login and sign up processes are all done but i was thinking of creating a unique id of some sort for when the user logs in. or something like this site (forum.phpfreaks) when we sign in, you are signed but the url stays the same = forums.phpfreaks.com. like if we were signed out we will be permanantly signed out and typing in forums.phpfreaks.com would just land us at the main page where we need to sign in.  right now ,my home.php can be accessed with or without logging in even with sessions.   hope im making sense, thanks in advanced!    **haha that rhymed.    i tried adding:   <?php echo $_SERVER[PHP_SELF] . '?name=' . $userData['name'];?> in the index.php:

<?php
ob_start();
session_start();
 
if(isset($_POST['login']))
{
	$email = $_POST['email'];
	$password = $_POST['pass'];
	 
	 require "connection.php";
	 
	$emails = mysqli_real_escape_string($con, $email);
	$query = "SELECT id, name, email, password, salt FROM users WHERE email = '$emails';";
	 
	$result = mysqli_query($con, $query);
	 
	if(mysqli_num_rows($result) == 0) // User not found. So, redirect to login_form again.
	{
		echo "<script>alert(\"User does not exist!\")</script>";
	}
	 
	$userData = mysqli_fetch_array($result, MYSQLI_ASSOC);
	$hash = hash('sha256', $userData['salt'] . hash('sha256', $password) );
	 
	if($hash != $userData['password'])
	{
		echo "<script>alert(\"Incorrect Password!\")</script>";
	}else{ 
		session_regenerate_id();
		$_SESSION['sess_user_id'] = $userData['id'];
		$_SESSION['sess_name'] = $userData['name'];
		session_write_close();
		header('Location: home.php?user=');
	}
}
ob_flush();
?>
<!DOCTYPE html>
<form name="login" method="post" action="<?php echo $_SERVER[PHP_SELF] . '?name=' . $userData['name'];?>">

but i got access forbidden!

Hey everyone!

My upcoming site will host, potentiallly thousands of photographs, and i was wondering how to go about having a unique ip hit counter for EACH image.

Obviously i dont want people refreshing the page to gain hits, therefore the hit counter will need to be dependent on the IP address.
I have used google and found a few hit counters however i need to know how to make this practical as it seems like it will require a lot of databases!


Thanks in advanced, Jimmy.

Hey guys. I need to know how to get a time that is constant. What I want to achieve:
I need to make a clock on my website showing only one time (HH:MM:SS), wherever the page is requested from.
And I need to use this "time" in calculations, like finding the time difference between two time values stored in my MYSQL Databases.
I hope that I am clear with my question.
Thanks for any help in advance!
