Hello.
Well i'm trying to make a timer to execute some code.
Basically I want 3 minutes, every 3 minutes a piece of code is activated, then another 3 minutes later it does so again.
But I have tried different ways of doing this, I tried with cookies and found out the person with the cookie is the only one that can refresh the page to activate the code.
Same with sessions.
And all the others are usually interrupted and start the timer again when the page reset.

So yeah, I don't want it to be interrupted by refreshing.
So any help please?
I also tried with timestamps, this has proven to be the best way but I can never get it working 100%

How am i able to setup a countdown timer?
I use the time(); function and want to compare that time with another time that is 8 hours ahead to form a countdown timer, how am i able to do this using php?

Hey Guy's   I need a quick fix to solve an urgent problem..   I used to do some coding years ago but the old grey matter is not so responsive these days and I have been up all night trying to resolve a problem.   I have built a website for my daughters and created a simple web form but I have come unstuck. All those skills I once took for granted are gone.   So here's where I am at. I've created an input form_mail.html, a contact.php and a reply.html page uploaded them to the Server and hit an error when I tried to send a message. The problem it seems is with the PHP.ini File.   In short I don't have one Duh! Yes I know I should go back and study and that much I intend to do I am currently installing xxampp, MySQL and php on my new laptop.   But in the meantime I need your help urgently..   What code do I need in the php.ini file to make the Form Mail work?   Is there somewhere on the web where I can see a simple code, I am just too tired to wade through heavy docs right now.   Your help would be much appreciated at this time.   Sincerely   Tam        

Hi all,

I would like to create a timer showing a countdown from 0% to 100% (representing "power") ending at noon GMT on Sunday 4th September.
The countdown started a few weeks ago, hence as of 1pm GMT on Tuesday 1st March, the countdown should be at 15%
The "power" increases by 5% every 11 days so by my calculations, the percentage in our countdown should increase by 0.01% every 1900.8 seconds.

So, with this theory, how would I go about coding it?

I guess since I use GMT, I need to take a timestamp in GMT first, then calculate the difference between this and Sunday 4th September at 12.00pm.

I am not sure though which format of time/date is best to do the calculation. Would it be better to use Unix time?

Any help, suggestions and/or code is greatly appreciated.

I am currently in the process of creating an online time based game. One of the big things is that users get gold every half an hour :00 & :30. What I am trying to do is offer a physical clock so that users can see how much time is left before they more more gold. I have been trying to do this using PHP.

All I have currently is the time, but would like something like "$minutes until more gold".

This is currently what I have now: (added 1 hour for EST.)
<?php echo date("h:i A",time()+60*60); ?>

I don't know if this can be done in PHP, but what I'm wanting to do is calculate the amount of time a user has spent in a session. I am planning on making a script that allows users to race through questions and the person who does it the fastest is the winner. Could someone help me out with this? Thanks

I am looking for a tutorial or advice wherein I can create a timer for my auction items. You can see those timers on the site like quibids.com The concept is like this.

I post and auction and set an end time for the auction. When the auction is live, The timer will start and will show how many hours and seconds are remaining. If any one has a class or some link to a tutorial site, that'll be a great help.

Thanks a lot.

Hi im trying to Make a Timer count down in this code

 function getTime($host, $user, $pass, $db, $hours, $ip, $serverId) {
  $c = @mysql_connect($host, $user, $pass);
      if(mysql_select_db($db, $c)) {
              $dateQ = mysql_query('SELECT MAX(date) AS lastVoteDate FROM `'. $db .'`.`votes` WHERE ip="'. $ip .'"') or die(mysql_error());
              $getDate = mysql_fetch_assoc($dateQ);
              $diffrence = time() - strtotime($getDate['lastVoteDate']);
              $hours = number_format(($diffrence / 60 / 60));
              $minutes = number_format(($hours / 60));
              if(!$hours < 1){
                return ("". $hours ."");
                } else {
                return ("0");
                }
      } else {
          return array(1, "Error connecting to DB.");
      }   
 }

Here's the code for the countdown timer. It works. At the end of the countdown, it's suppose to show the message "EXPIRED". But that message only shows once I reload the page. The countdown itself stops at 00:00:01. Is there a way to automatically show the message after that, instead of reloading the page to show it?

<style>
  div#counter{
      margin: 100px auto;
      width: 305px;
      padding:20px;
      border:1px solid #000000;
  }
  div#counter span{
      background-color: #00CAF6;
      padding:5px;
      margin:1px;
      font-size:30px;
  }
</style>

<?php 
  $target_date = '2019-01-12 05:40:00';
  $timeLeft = (strtotime($target_date) - time()) * 1000;
?>
<script src="javascripts/timer.js"></script>
<script>
$(document).ready(function(){

      var timeLeft = <?php echo $timeLeft ; ?>;
      var timer =  new Timer($('#counter'), timeLeft);
      
      if (timeLeft <= 0) {
        $('#counter').text('EXPIRED');
      }

});
</script>
<div id="counter">
  <span class="hour">00</span>
  <span class="min">00</span>
  <span class="sec">00</span>
</div>

Can anyone help me with a 60 second timer for my website. I want to display the following text to my customers at the top of the page: "You will be automatically redirected to homepage in [timer]"

In my header I have the following code: <meta http-equiv="refresh" content="61;url=home.php">

Is it possible to set a certain session to time out after say 2 minutes. I want to lock a person from seeing a page for 2 minutes then destroy the session yet keep the primary session and still keep dpoing what they were doing? Just curious.

Thanks,

Hello.
Well I am really annoyed at myself at the moment.
I am trying to make a timer script that is uninterrupted by a refresh of the page, so this to me would be a Mysql database thing to check

My idea was simple, at least until I forgot it.
But, I was going to grab the current time using time();
and place it into the database.
Then I would set another value in the structure called check, to 1.

The database while the value is set on 1 will keep checking every time a user refreshes.
It would get the time from the database that was set, and the current time again. It would take away the stored time from the current time and if that value equals less then ten, it would keep running the script and won't change the check. But if it was over ten, it would do a random function (What ever the user wanted, right now it just an echo for a test) and delete both the current timestamp in the database, and set the check to 0.

If the value was 0, it would set the new timestamp in the database, eg the current time, and set the value to 1 so it will keep running again.

Is this possible?
It is getting a bit annoying, getting a few errors, again like most of the time its little ones that I can't seem to put my finger on.
Hey, we have all started somewhere :/

This is my code so fa

Code: [Select]
<?php

$db = mysql_pconnect("localhost","root",""); 
mysql_select_db("test",$db);

$time = time();
$result = mysql_query("SELECT * FROM timer");

while($row = mysql_fetch_array($result))
  {
  $timestamp = $row['timestamp'];
  $check = $row['check'];
  }

if ($check=="0") {
$query = "UPDATE timer SET check = '1' WHERE id = '1'";
$query .= "UPDATE timer SET timestamp = '$time' WHERE id = '1'";
multi_query($query);
}
elseif ($check=="1") {
$timenow = time();
$timecheck = $timenow - $timestamp;

if ($timecheck >= "10") {
echo "bigger then 10, do what ever at the end of the countdown here";
$query2 = "UPDATE timer SET check = '0' WHERE id = '1'";
$query2 .= "UPDATE timer SET timestamp = '' WHERE id = '1'";
multi_query($query2);
}

}

?>

Now even looking at this code confuses me, and I wrote it.
I tested it, I expected an error and got one.

As you have probably already stated, I am a very small form of BASIC at PHP, would anyone like to push me in the right direction as to how to get this working?

Hey guys.
My question is simple.
I have a time value of the future, in seconds, that I extract from MySQL.
time();
How do I make an interactive countdown timer using it? It should show the numbers ticking away.
I tried Javascript, but it doesn't go with the php time layout.
Can anyone help me here?

Thanks!
