How to detect if current date is greater than datetime? - 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';
}
}

How can I echo if a user is online or offline?

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) );
?>

PHP - subtracting time return nothing

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
Link to the function.

Is mysql datetime not compatible with strtotime()?

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");

Displaying Date In A User Formated Style with php

I've noticed that Facebook, Twitter, and lots of other sites are using a relative date and time string description for user posts and comments.
For example, "comment written about 3 months ago" instead of "comment written on September 20, 2012." I decided to do the same thing on my site. In my site I need to display 1 day ago, 2 days ago, 3 days ago,...... 1 week ago, 2 weeks ago, .... 1 months ago, 2 months ago, ...... 1 year ago, 2 years ago... etc.
Already I have got user registered date and need to check it with current date and time and need to diplay it with above style on my home page.
In my database, user registered date format is like this .. '2012-09-23 09:11:02'
can anybody help me to build this script in php... and it will greatly appriciated.
Thank you.
Try the following code,
function time_elapsed_since ($postedDateTime){
$time = time() - $postedDateTime; // 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.(($numberOfUnits>1)?'s':'');
}
}
Usage:
time_elapsed_since($postedDateTime).' ago'; // 2012-09-23 09:11:02 format
Try with this
function time_ago($time) {
$periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
$lengths = array("60","60","24","7","4.35","12","10");
$now = time();
$difference = $now - $time;
$tense = "ago";
for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
$difference /= $lengths[$j];
}
$difference = round($difference);
if($difference != 1) {
$periods[$j].= "s";
}
return "$difference $periods[$j] 'ago' ";
}
Im guessing they are using unixtime ie the number of seconds since 1970 (which is standard). I suggest that should also keep your dates in that format. If they are using unix time you can use the following date function in PHP to convert it to your format above:
<?php
date('Y-m-t H:i:s', $facebookTime);

How to convert seconds to time format? [duplicate]

This question already has answers here:
Convert seconds to Hour:Minute:Second
(30 answers)
Closed 9 years ago.
For some reason I convert a time format like: 03:30 to seconds 3*3600 + 30*60, now. I wanna convert it back to its first (same) format up there. How could that be?
My attempt:
3*3600 + 30*60 = 12600
12600 / 60 = 210 / 60 = 3.5, floor(3.5) = 3 = hour
Now, what about the minutes?
Considering the value can be like 19:00 or 02:51.
I think you got the picture.
And by the way, how to convert 2:0 for example to 02:00 using RegEx?
This might be simpler
gmdate("H:i:s", $seconds)
PHP gmdate
$hours = floor($seconds / 3600);
$mins = floor($seconds / 60 % 60);
$secs = floor($seconds % 60);
If you want to get time format:
$timeFormat = sprintf('%02d:%02d:%02d', $hours, $mins, $secs);
If the you know the times will be less than an hour, you could just use the date() or $date->format() functions.
$minsandsecs = date('i:s',$numberofsecs);
This works because the system epoch time begins at midnight (on 1 Jan 1970, but that's not important for you).
If it's an hour or more but less than a day, you could output it in hours:mins:secs format with `
$hoursminsandsecs = date('H:i:s',$numberofsecs);
For more than a day, you'll need to use modulus to calculate the number of days, as this is where the start date of the epoch would become relevant.
Hope that helps.
Maybe the simplest way is:
gmdate('H:i:s', $your_time_in_seconds);
Let $time be the time as number of seconds.
$seconds = $time % 60;
$time = ($time - $seconds) / 60;
$minutes = $time % 60;
$hours = ($time - $minutes) / 60;
Now the hours, minutes and seconds are in $hours, $minutes and $seconds respectively.
Another solution that will give you the days, hours, minutes, and seconds for a passed-in seconds value:
function seconds_to_time($secs)
{
$dt = new DateTime('#' . $secs, new DateTimeZone('UTC'));
return array('days' => $dt->format('z'),
'hours' => $dt->format('G'),
'minutes' => $dt->format('i'),
'seconds' => $dt->format('s'));
}
print_r(seconds_to_time($seconds_value);
Extra logic will be needed for 'days' if the time is expected to be more than one year. Use str_pad() or ltrim() to add/remove leading zeros.
ITroubs answer doesn't deal with the left over seconds when you want to use this code to convert an amount of seconds to a time format like hours : minutes : seconds
Here is what I did to deal with this:
(This also adds a leading zero to one-digit minutes and seconds)
$seconds = 3921; //example
$hours = floor($seconds / 3600);
$mins = floor(($seconds - $hours*3600) / 60);
$s = $seconds - ($hours*3600 + $mins*60);
$mins = ($mins<10?"0".$mins:"".$mins);
$s = ($s<10?"0".$s:"".$s);
$time = ($hours>0?$hours.":":"").$mins.":".$s;
$time will contain "1:05:21" in this example.
If you were to hardcode it you would use modulus to extract the time as others suggested.
If you are returning the seconds from MySQL database, assuming you don't need the data in seconds format in your app, there is a much cleaner way to do it, you can use MySQL's SEC_TO_TIME and it will return time in hh:mm:ss format.
Eg.
SELECT SEC_TO_TIME(my_seconds_field) AS my_timestring;
Sorry this is too late but maybe useful
function mediaTimeDeFormater($seconds)
{
if (!is_numeric($seconds))
throw new Exception("Invalid Parameter Type!");
$ret = "";
$hours = (string )floor($seconds / 3600);
$secs = (string )$seconds % 60;
$mins = (string )floor(($seconds - ($hours * 3600)) / 60);
if (strlen($hours) == 1)
$hours = "0" . $hours;
if (strlen($secs) == 1)
$secs = "0" . $secs;
if (strlen($mins) == 1)
$mins = "0" . $mins;
if ($hours == 0)
$ret = "$mins:$secs";
else
$ret = "$hours:$mins:$secs";
return $ret;
}
echo mediaTimeDeFormater(216.064000);//3:36
something like this?
if(is_numeric($time)){
$value = array(
"years" => 0, "days" => 0, "hours" => 0,
"minutes" => 0, "seconds" => 0,
);
if($time >= 31556926){
$value["years"] = floor($time/31556926);
$time = ($time%31556926);
}
if($time >= 86400){
$value["days"] = floor($time/86400);
$time = ($time%86400);
}
if($time >= 3600){
$value["hours"] = floor($time/3600);
$time = ($time%3600);
}
if($time >= 60){
$value["minutes"] = floor($time/60);
$time = ($time%60);
}
$value["seconds"] = floor($time);
return (array) $value;
} else{
return (bool) FALSE;
}
grabbed from: http://www.ckorp.net/sec2time.php
Use modulo:
$hours = $time_in_seconds / 3600;
$minutes = ($time_in_seconds / 60) % 60;
just one small additional example
requested time in miliseconds
// ms2time( (microtime(true) - ( time() - rand(0,1000000) ) ) );
// return array
function ms2time($ms){
$return = array();
// ms
$return['ms'] = (int) number_format( ($ms - (int) $ms), 2, '', '');
$seconds = (int) $ms;
unset($ms);
if ($seconds%60 > 0){
$return['s'] = $seconds%60;
} else {
$return['s'] = 0;
}
if ( ($minutes = intval($seconds/60))){
$return['m'] = $minutes;
}
if (isset($return['m'])){
$return['h'] = intval($return['m'] / 60);
$return['m'] = $return['m'] % 60;
}
if (isset($return['h'])){
$return['d'] = intval($return['h'] / 24);
$return['h'] = $return['h'] % 24;
}
if (isset($return['d']))
$return['mo'] = intval($return['d'] / 30);
foreach($return as $k=>$v){
if ($v == 0)
unset($return[$k]);
}
return $return;
}
// ms2time2string( (microtime(true) - ( time() - rand(0,1000000) ) ) );
// return array
function ms2time2string($ms){
$array = array(
'ms' => 'ms',
's' => 'seconds',
'm' => 'minutes',
'h' => 'hours',
'd' => 'days',
'mo' => 'month',
);
if ( ( $return = ms2time($ms) ) && count($ms) > 0){
foreach($return as $key=>$data){
$return[$key] = $data .' '.$array[$key];
}
}
return implode(" ", array_reverse($return));
}
Here is another way with leading '0' for all of them.
$secCount = 10000;
$hours = str_pad(floor($secCount / (60*60)), 2, '0', STR_PAD_LEFT);
$minutes = str_pad(floor(($secCount - $hours*60*60)/60), 2, '0', STR_PAD_LEFT);
$seconds = str_pad(floor($secCount - ($hours*60*60 + $minutes*60)), 2, '0', STR_PAD_LEFT);
It is an adaptation from the answer of Flaxious.
If You want nice format like: 0:00:00 use str_pad() as #Gardner.
1 day = 86400000 milliseconds.
DecodeTime(milliseconds/86400000,hr,min,sec,msec)
Ups! I was thinking in delphi, there must be something similar in all languages.
