here iam getting admin login date and time detail.But i unable to get previous visitor login detail . i can just see only my login time/date detail after login in here.
So please help.

I can give you the basic logic for this. In this you can set the session variable that it will act as flag.
// start session
session_start();
// if not yet logged in update database
if(!isset($_SESSION['logged']))
{
// update your database here
$query = "UPDATE table
SET LastLogin=now()
WHERE ID='$ID'";
$result = mysql_query($query); // etc...
// if the table was updated
if($result === true)
{
// then create a session var
$_SESSION['logged'] = 1;
}
}
OR
You can insert the user id, date and time at the time of login and get it back as last id that will be your previous login.

Create one activity table in database. Click the link to view example here->
User Activity Table Structure
Every time when any user logs in, just enter the login time and user id along with other required details in the activity table. At the time of login you can change the login status to deactivated for that particular session.
Next time when any user logs in you can get the last login time from database and current time from PHP date() function. Just get the time difference between those 2 dates and you will get the last login time and duration by previous user.
That's it.
Hope this would work.

The calender works well, but when the first day in the month is Sunday, then it starts to count the days from Monday (for example May 2016). How do I fix this?

Try the following code
if($i == 1)
{
$firstDay = date("w", $timeStamp) - 1;
if ($firstDay < 0)
$firstDay = 6;
// Now monday is 0, and sunday is 6
for($j = 0; $j < $firstDay; $j++, $counter++) // remove the -1 in $firstDay-1
{
echo "<td> </td>";
}
}
The first column of your calendar is Monday, and the last column is Sunday. $firstDay = date("w", $timeStamp) returns a number from 0-6 where 0 is Sunday, and 6 is Saturday. So I change it so that 0 is Monday, and 6 is Sunday.
So now the loop for($j = 0; $j < $firstDay; $j++, $counter++)
If Monday, then since it's the first column you don't want the loop to run. On Monday, $firstDay is 0 so the loop doesn't run. If Tuesday, then $firstDay is 1 and the loop runs once to make the empty space for Monday.

creating custom time algorith like timeago in javascript

I want a custom time algorithm like javascript. I was able to achieve this using php but am not able to do the same with javascript!
WHat i had in php was like.....
PHP FIDDLE(i want something like this in js output)
function getTime($mytime){
// $mytime is a datetime sql database format time
$thetime = strtotime($mytime);
$q = new DateTime($mytime);
$current_time = date('Y-m-d H:i:s',time());
$w = new DateTime($current_time);
$result = $w ->diff($q);
$string = "";
$year = $result->y;
$month = $result->m;
$day = $result->d;
$hour = $result->h;
$min = $result->i;
$sec = $result->s;
if($year==0){
if($month==0){
if($day==0){
if($hour==0){
if($min==0){
if($sec <30){
$string .= "Just now";}else if($sec<60){ $string .= "A few seconds ago";}
}else{
if($min<5){$string .="A few minutes ago";}else if($min>=5){$string .=$min . ' minutes ago'; }
}}else{
if($hour<6){$string .=$hour . ' hours ago';}else if($hour>=6){
$chour = (date('H',$thetime));
if( ($chour>=5)&&($chour<=17) ){$string .= 'Today at ' .date('h.m a',$thetime);}else{$string .= 'Tonight at '. date('h.m a',$thetime);}}
}}else{
if($day==1){$string .= "Yesterday at " . date('h:m a',$thetime);}else if(($day>1) && ($day<=7)){$string .= $day . " days ago";}else if($day>7){$string .= date('M, d',$thetime) . ' at '. date('h:i a',$thetime);}
}}else{
if($month<5){$string .=$month . ' months ago'; }else if($month>=5){$string .= date('M,d',$thetime) .' at ' . date('h.i a',$thetime) ;}
}}else{
$string .=date('dS M , Y',$thetime) .' at '. date('h.i a',$thetime);
}
return $string;
}
What i thought was to dynamically update time using javascript! so i did this......
$(function(){
var $second = 1000;
var $minute = $second * 60;
var $hour = $minute * 60;
var $day = $hour * 24;
setInterval(function(){
$('.comment').each(function(){
var $this = $(this);
var $time = new Date($this.attr('datetime'));
var $now = new Date();
var $distance = $now - $time;
var $days = Math.floor($distance / $day);
var $hours = Math.floor(($distance % $day) / $hour);
var $minutes = Math.floor(($distance % $hour) / $minute);
var $seconds = Math.floor(($distance % $minute) / $second);
var $time_string = '';
if($days > 0) {
$time_string = $time_string + $days + ' Day(s) ';
}
if($hours > 0) {
$time_string = $time_string + $hours + ' Hour(s) ';
}
if($minutes > 0) {
$time_string = $time_string + $minutes + ' Minute(s) ';
}
if($seconds > 0) {
$time_string = $time_string + $seconds + ' Second(s)';
}
$this.text($time_string);
});
}, 1000);
});
but his outputs something like this fiddle here.
What i wanted is like my prev. php output i.e X min ago or X seconds ago or 12 May 2014 etc how do i implement my above php code with this js ?

Javascript countdown just working on Chrome

Well, I'm making a game, and in my game I have a countdown script in javascript that receives the date when the building upgrade is over, and makes a countdown, and when the countdown ends, executes a script that upgrades the building to the next level.

The format of $factory_date is invalid according to standard JavaScript and Chrome happens to be able to parse it.
For better results, stick to these Date constructors:
new Date();
new Date(value);
new Date(dateString);
new Date(year, month [, day, hour, minute, second, millisecond]);

Javascript/PHP countdown timer stops at a certain time?

I have this code for a countdown timer. its basically a combination of PHP/Javascript countdown timer which will gets the $end_date from a Mysql table/field.
The problem is that it will stop automatically (which is unwanted) at a certain time.
For example: I set the $end_date to September 19 2013 11:30:00 AM GMT in mysql database.
the countdown starts and works fine and starts counting down as it should. However, when the countdown timer reaches September 19 2013 13:00:00 PM GMT it will stop and it will show the Times Up message! Basically it will stop working or counting down once the $end_date has been changed to 13:00:00 PM.
I cannot see anything in my code that will cause this issue. apart from this line:
if ($now < $exp_date ) {
?>
but again, this line only tells the script when to start counting and as far i can see it shouldn't stop the countdown timer to stop as long as the timer has not reached the $end_date. or am I missing something?
here is my code:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php date_default_timezone_set('GMT'); ?>
<?php
session_start();
// Run a select query to get my letest 6 items
// Connect to the MySQL database
include "config/connect.php";
$dynamicList = "";
$sql = "SELECT * FROM item ORDER BY id";
$query = mysqli_query($db_conx, $sql);
$productCount = mysqli_num_rows($query); // count the output amount
if ($productCount > 0) {
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
$id = $row["id"];
$product_name = $row["product_name"];
$date_added = date("Y-m-d", strtotime($row["date_added"]));
$end_date = date("F d Y H:i:s A T", strtotime($row["end_date"]));
$price = $row["price"];
$dynamicList .= '<div>' . $end_date . '
</div>';
}
} else {
$dynamicList = "No Records";
}
?>
<?php
$date = $end_date;
$exp_date = strtotime($date);
$now = time();
if ($now < $exp_date ) {
?>
<script>
// Count down milliseconds = server_end - server_now = client_end - client_now
var server_end = <?php echo $exp_date; ?> * 1000;
var server_now = <?php echo time(); ?> * 1000;
var client_now = new Date().getTime();
var end = server_end - server_now + client_now; // this is the real end time
var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour *24

{
var now = new Date();

if (distance < 0 ) {
clearInterval( timer );

}
var days = Math.floor(distance / _day);
var hours = Math.floor( (distance % _day ) / _hour );

any help would be greatly appreciated.

13:00:00 PM is not a valid time. AM and PM are used to indicate which side of the 12-hour cycle the time is. You cannot logically say you're on the 13th hour of the 12 hour side of the clock.
EDIT: For clarity: 13:00 == 1 PM, 13:00 PM == nothing.
