I found a function form SC to output human readable time. like `
5 hours, 1 hour, 5 years, etc
function human_time ($time)
{
$time = time() - strtotime($time); // to get the time since that moment
$tokens = array (
31536000 => 'year',
2592000 => 'month',
604800 => 'week',
86400 => 'day',
3600 => 'hour',
60 => 'minute',
1 => 'second'
);
foreach ($tokens as $unit => $text) {
if ($time < $unit) continue;
$numberOfUnits = floor($time / $unit);
return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
}
}
And I have time as string: 2013-09-28 20:55:42
when I call this function human_time('2013-09-28 20:55:42')
then it return nothing, why ?
I have added strtotime in above function.
Please tell me what is wrong.
This is no ready-to-use code, but rather supposed to guide you the right way:
$then = new DateTime($time); // you might need to format $time using strtotime or other functions depending on the format provided
$now = new DateTime();
$diff = $then->diff($now, true);
echo $diff->format('Your style goes here');
See DateTime Manual for further documentation or feel free to ask here.
Edit: Link fixed.
Use example :
echo time_elapsed_string('2013-05-01 00:22:35');
echo time_elapsed_string('2013-05-01 00:22:35', true);
Output :
4 months ago
4 months, 2 weeks, 3 days, 1 hour, 49 minutes, 15 seconds ago

I have a function like this:
function time_elapsed_string($ptime)
{
$date_time = strtotime("1348-10-10 04:30:01") + $ptime;
$year = date("Y",$date_time);
$month = date("m",$date_time);
$day = date("d",$date_time);
$time = date("H:i:s",$date_time);
$etime = time() - $ptime + 1;
$a = array( 31536000 => 'year',
2592000 => 'month',
86400 => 'day',
3600 => 'hour',
60 => 'minute',
1 => 'second'
);
foreach ($a as $secs => $str)
{
$d = $etime / $secs;
if ($d >= 1)
{
$r = round($d);
// EX:
return array('date' => $day.'-'.$month.'-'.$year, // 2016-02-20
'time' => $time, // 03:30:04
'difference' => $r . ' ' . $str . ' ago' // 2 month ago
);
}
}
}
And I use it like this:
$ptime = 1470692661;
$html = '<span title="date: '.time_elapsed_string($ptime)['date'].' time: '.time_elapsed_string($ptime)['time'].'">in '.time_elapsed_string($ptime)['difference'].'<span>';
As you see, I'm using of that function's result like this:
time_elapsed_string($ptime)['date']
ime_elapsed_string($ptime)['time']
time_elapsed_string($ptime)['difference']
In fact I'm calling that function every time I need one of its results. Is that right? Or should I call it once and store it into an array?
Note: My code works as well.
Counting time elapsed since some date/time like this is mauvais ton.
DateTime has been available since PHP 5.2.0 and tonns of people underestimate it. Why don't you use this instead of loops and ifs?
$create_time = "2016-08-02 12:35:04";
$current_time="2016-08-02 16:16:02";
$dtCurrent = DateTime::createFromFormat('Y-m-d H:i:s', $current_time);
// to use current timestamp, use the following:
//$dtCurrent = new DateTime();
$dtCreate = DateTime::createFromFormat('Y-m-d H:i:s', $create_time);
$diff = $dtCurrent->diff($dtCreate);
Now, you can format the result however you want:
$interval = $diff->format("%h hours %i minutes %s seconds");
This will give a clean 3 hours 40 minutes 58 seconds without any arrays, which is better.
UPDATE
There is a general solution to get hours / minutes / seconds via regex:
$interval = $diff->format("%y years %m months %d days %h hours %i minutes %s seconds");
// now remove zero values
$interval = preg_replace('/(^0| 0) (years|months|days|hours|minutes|seconds)/', '', $interval);
UPDATE 2
As of your comment:
Look, I want to use your approach .. but I really cannot implement it .. Actually I need three things: time, date, difference ..! But your approach doesn't give me them..
Well, we already know how to get the difference, it's the $interval variable described above.
To get time and date, you can get it from the $dtCreate variable by, again, using format:
$time = $dtCreate->format('H:i:s');
$date = $dtCreate->format('d-m-Y');
This is a no brainer.
Yes - store the function call result of time_elapsed_string($ptime) in an array, then use that to access your results. You're wasting CPU cycles otherwise!
// call it once
$result = time_elapsed_string($ptime);
// then use:
$result['date'];
$result['time'];
$result['difference'];
I found a code that transform a timestamp from when a user last logged in. It really short but works just fine displaying x seconds, 2 days, etc.
The problem is that i wish to transform the first x minutes (max 5min) to say <div class="green">ONLINE</div>
heres the php:
<?php
function humanTiming ($time)
{
$time = time() - $time; // to get the time since that moment
$time = ($time<1)? 1 : $time;
$tokens = array (
31536000 => 'year',
2592000 => 'month',
604800 => 'week',
86400 => 'day',
3600 => 'hour',
60 => 'minute',
1 => 'second'
// Tried to replace seconds with <div class="green">ONLINE</div>
// but will end up looking like x ONLINEs where x = seconds
);
foreach ($tokens as $unit => $text) {
if ($time < $unit) continue;
$numberOfUnits = floor($time / $unit);
return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
}
}
echo humanTiming( strtotime($user_last_life) );
?>
Followup question :
What is the most secure and best way to update a database with timestamp?
I have problems having it update after login but have added this code in my head.php
$updated_life_id = htmlentities($_SESSION['user']['id'], ENT_QUOTES, 'UTF-8');
$set_last_life = "UPDATE users SET last_life = time() WHERE id = '$updated_life_id'";
$datab->query($set_last_life);
if(strtotime($user_last_life) >= time()-300) // 300 seconds = 5 minutes
{
echo '<div class="green">ONLINE</div>';
}
And for your database question
How can I prevent SQL injection in PHP?
Actually I'd like to create a function which return me the date if the day is greater than one and it should return the time age like 1 hour ago.
I have done almost 80%, Time Ago functionality now I want to add one more feature.
function dateTimeExe ($time)
{
$time = time() - $time; // to get the time since that moment
$tokens = array (
31536000 => 'year',
2592000 => 'month',
604800 => 'week',
86400 => 'day',
3600 => 'hour',
60 => 'minute',
1 => 'second'
);
foreach ($tokens as $unit => $text) {
if ($time < $unit) continue;
$numberOfUnits = floor($time / $unit);
return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
}
}
Please view output it may help to understand my question.
If day is less than 1 then it is working properly // 1 min ago or 1 hour ago
Now I want to add if day is greater than 1 then it should return date in this format // 18 May 2015.
What you can do is getting the timestamp from your datetime (http://php.net/manual/fr/class.datetime.php) thanks to getTimestamp() method and finally you can compare them with each other
Assuming $date is a Datetime instance :
$time = time() - $time->getTimestamp();
Actually, I add if statement in my function and now its working
if ($time>86400) {
return date('d F Y');
}else{
foreach ($tokens as $unit => $text) {
if ($time < $unit) continue;
$numberOfUnits = floor($time / $unit);
return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'').' ago';
}
}
I'm passing this function a mysql datetime and it is returning nothing. Is mysql datetime not compatible with strtotime()? I assume that the foreach loop is ending and the return variable is not being called, but why?
function timeAgo($time) {
$time = time() - strtotime($time); // to get the time since that moment
$tokens = array (
1 => 'second',
60 => 'minute',
3600 => 'hour',
86400 => 'day',
604800 => 'week',
2592000 => 'month',
31536000 => 'year'
);
foreach ($tokens as $unit => $text) {
if ($time < $unit) continue;
$numberOfUnits = floor($time / $unit);
return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'').' ago';
}
}
Update This is the code that gets it from the database, there are no quotes in the datetime string.
while ($row = mysqli_fetch_assoc($result)) {
$commentTime = $row["time"];
$commentComment = $row["comment"];
$commentCommenter = $row["commenter"];
}
And this is the code to echo it: echo '<h3 class="party-time">'.timeAgo($commentTime).'</h3>';
The problem was a timezone issue. I was manually setting the date in the SQL server I was using which set the datetime to my local time, but the server's timezone was -3 hours, causing issues.
We cannot tell what $time holds exactly, but when you feed an ISO-8601 date to strtotime, it works fine:
php > echo strtotime("2013-08-01 12:00:00");
1375351200
I am trying to calculate time passed since a comment is posted. I found a function for this and it's working well
But I just noticed the time shown to user is wrong because of his/her timezone. I did some research and the solution seems to be passing the user's timezone offset to the php page using a javascript function called getTimezoneOffset.
the problem is that I can't manage to use this Offset to make a timezone and use it on that function I linked above. With the help of another code is what I could gather so far :
function humanTiming ($time,$offset)
{
$isDST = 1; // Daylight Saving 1 - on, 0 - off
$timezoneName = timezone_name_from_abbr('', intval($offset, 10) * 36, $isDST);
$date = new DateTime($time, new DateTimeZone($timezoneName));
$time = strtotime($date);
$time = time() - $time; // to get the time since that moment
$tokens = array (
31536000 => 'year',
2592000 => 'month',
604800 => 'week',
86400 => 'day',
3600 => 'hour',
60 => 'minute',
1 => 'second'
);
foreach ($tokens as $unit => $text) {
if ($time < $unit) continue;
$numberOfUnits = floor($time / $unit);
return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
}
}
And let's call the function like this :
echo humanTiming ($row['date'],"-240");
note : -240 is the value I get from running that javascript function, So it is probably my timezone offset.
First issue: It seems the value -240is invalid and something like -0500 works.
Second issue: even If I try with the valid offset value, the function returns 42 years
Not sure how this 42 years is calculated but its totally wrong.
A couple of problems:
The Javascript function getTimezoneOffset() returns the timezone offset in minutes, however timezone_name_from_abbr() expects the offset in seconds. So in your example of -240 that is actually -4 hours or -14396 seconds. You can fix your code by changing the math a little:
$timezoneName = timezone_name_from_abbr('', intval($offset) * 60, $isDST);
Since you've started using the DateTime object, you can't then use strtotime to get the Unix timestamp. Instead you need format():
$date = new DateTime($time, new DateTimeZone($timezoneName));
$time = $date->format('U');
This should get the result you are after. You were getting 42 years because the time was set to 0 (strtotime($date) evaluated to false) which is Unix epoch - 1970.
You could offset everything like so:
$today=new DateTime("-$offset minutes");
$tomorrow=new DateTime("+1 day-$offset minutes");
