PHP: producing relative date/time from timestamps
please see the example of PHP code:
<?php
$now = date("Y-m-d H:i:s");
$comment_added = date("2012-05-25 22:10:00");
?>
As the output, I would like to get something like this (depending on when a comment has been added):
Comment has been added 21 minutes ago.
Comment has been added 15 hours ago.
Comment has been added 2 days ago.
Comment has been added 3 months ago.
Comment has been added 4 years ago.
I would like to get a function, where it will be selected automatically. Any examples would be appreciated.

This should work.
<?php
$now = date("Y-m-d H:i:s");
$comment_added = date("2012-05-25 22:10:00");
$diff = strtotime($now) - strtotime($comment_added);

$type = 'month';
$value = floor($diff / (30*24*3600));
} else if ($diff > (24*3600)) {
$type = 'day';
$value = floor($diff / (24*3600));
} else if ($diff > 3600) {
$type = 'hour';
$value = floor($diff / 3600);
} else if ($diff > 60) {
$type = 'min';
$value = floor($diff / 60);
} else {
$type = 'sec';
$value = $diff;
}
$plurial = '';
if ($value > 1)
{
$plurial .= 's';

How to get the result into a variable?

Might be a kinda noob question.
But I currently have this code:
<?php
$seconds = 1;
$h = (int)($seconds / 3600);
$m = (int)(($seconds - $h*3600) / 60);
$s = (int)($seconds - $h*3600 - $m*60);
if ($h > 1)
echo "$h hours ago";
else if ($m > 1)
echo "$m minutes ago";
else if ($s > 20)
echo "$s seconds ago";
else echo "a moment ago";
$ThisTime = result
?>
Reminder: seconds is a variable that normally gets defined by an other variable.
What I want is:
for instance with "seconds = 1", the output is: "a moment ago". But i want that echo to be
$ThisTime, how can i do this.
Reminder 2: If the input is 400000, the output is: 111 hours ago. So it defines by multiple variables.
Stupid me:
<?php
$seconds = 1;
$h = (int)($seconds / 3600);
$m = (int)(($seconds - $h*3600) / 60);
$s = (int)($seconds - $h*3600 - $m*60);
if ($h > 1)
$Thistime = "$h hours ago";
else if ($m > 1)
$Thistime = "$m minutes ago";
else if ($s > 20)
$Thistime = "$s seconds ago";
else $Thistime = "a moment ago";
?>
EDIT :::::
Ok, i found another problem.
The time is specified in a database.
And it displays there like this: "1407922779"
How can I cahnge this value to be x minutes ago?
Because if i enter that, it says like 30 years ago (something like that).
While it just has been made.
<?php
$seconds = 1;
$h = (int)($seconds / 3600);
$m = (int)(($seconds - $h*3600) / 60);
$s = (int)($seconds - $h*3600 - $m*60);
if ($h > 1) {
$result = "$h hours ago";
} elseif ($m > 1) {
$result = "$m minutes ago";
} elseif ($s > 20) {
$result = "$s seconds ago";
} else {
$result = "a moment ago";
}
$ThisTime = $result;
?>

Best way to calculate human readable elapsed time [closed]

Closed 9 years ago.
I am wondering what is the most elegant way of calculating a human readable elasped time given a certain amount of seconds. I want to write this in PHP.
Here is the output needed:
elapsedTimeInSeconds > one year, output "# years, # months"
elapsedTimeInSeconds > one month, output "# months, # days"
elapsedTimeInSeconds > one day, output "# days, # hours"
elapsedTimeInSeconds > one hour, output "# hours, # minutes"
elapsedTimeInSeconds > one minute, output "# minutes, # seconds"
I have tried different solutions that are awkward and full of conditional statements, but I was hoping for a more recursive and "clean code" method.
I think this is more flexible, as you can easily add new units like decade, century, etc, and the code wouldn't change:
$names = array("seconds", "minutes", "hours", "days", "months", "years");
$values = array(1, 60, 3600, 24 * 3600, 30 * 24 * 3600, 365 * 24 * 3600);
$time = ...elapsedTimeInSeconds...;
for($i = count($values) - 1; $i > 0 && $time < $values[$i]; $i--);
if($i == 0) {
echo intval($time / $values[$i]) . " " . $names[$i];
} else {
$t1 = intval($time / $values[$i]);
$t2 = intval(($time - $t1 * $values[$i]) / $values[$i - 1]);
echo "$t1 " . $names[$i] . ", $t2 " . $names[$i - 1];
}
Thank you for your suggestions.
I mainly used Waygood and ChrisForrence's suggestions for this method. I tried to keep it as simple as possible and introduced simple arguments such as detail level and delimiter (for string ouput).
public function elapsedTimeHumanReadable($date = null, $detailLevel = 2, $delimiter = ' et ')
{
if($date === null)
{
$date = self::now();
}
$sec = $this->elapsedSecond($date);
$a_sec = 1;
$a_min = $a_sec * 60;
$an_hour = $a_min * 60;
$a_day = $an_hour * 24;
$a_month = $a_day * 30;
$a_year = $a_day * 365;
$text = '';
$resultStack = array();
if($sec >= $a_year)
{
$years = floor($sec / $a_year);
$text .= $years . $this->plural($years, ' an');
$sec = $sec - ($years * $a_year);
array_push($resultStack, $text);
}
if($sec >= $a_month)
{
$months = floor($sec / $a_month);
$text = $months . ' mois';
$sec = $sec - ($months * $a_month);
array_push($resultStack, $text);
}
if($sec >= $a_day)
{
$days = floor($sec / $a_day);
$text = $days . $this->plural($days, ' jour');
$sec = $sec - ($days * $a_day);
array_push($resultStack, $text);
}
if($sec >= $an_hour)
{
$hours = floor($sec / $an_hour);
$text = $hours . $this->plural($hours, ' heure');
$sec = $sec - ($hours * $an_hour);
array_push($resultStack, $text);
}
if($sec >= $a_min)
{
$minutes = floor($sec / $a_min);
$text = $minutes . $this->plural($minutes, ' minute');
$sec = $sec - ($minutes * $a_min);
array_push($resultStack, $text);
}
if($sec >= $a_sec)
{
$seconds = floor($sec / $a_sec);
$text = $sec . $this->plural($seconds, ' seconde');
$sec = $sec - ($sec * $a_sec);
array_push($resultStack, $text);
}
$result = $resultStack[0];
for($i = 1; $i <= $detailLevel - 1; $i++)
{
if(!empty($resultStack[$i]))
{
$result .= $delimiter . $resultStack[$i];
}
}
return $result;
}
I also added a very simple plural function to return the time unit in a correct grammatical fashion:
public function plural($value, $unit)
{
if($value > 1)
{
return $unit . 's';
}
else
{
return $unit;
}
}
I am not really happy with the for loop, but it actually works fine.
Anyway, thank you very much for your help!
I use this:
function durationFormat($time)
{
if(gmdate("Y", $time)>1970) return (1970-gmdate("Y",$time)).gmdate(" \y\r\s ", $time).(gmdate("n",$time)-1).gmdate(" \m\o\n\t\h\s ", $time).(gmdate("j",$time)-1).gmdate(" \d\a\y\s H:i:s", $time);
if(gmdate("n", $time)>1) return (gmdate("n",$time)-1).gmdate(" \m\o\n\t\h\s ", $time).(gmdate("j",$time)-1).gmdate(" \d\a\y\s H:i:s", $time);
if(gmdate("j", $time)>1) return (gmdate("j",$time)-1).gmdate(" \d\a\y\s H:i:s", $time);
return gmdate("H:i:s", $time);
}
It's a bit quick and dirty but does the job
OR
function durationFormat2($seconds)
{
$a_sec=1;
$a_min=$a_sec*60;
$an_hour=$a_min*60;
$a_day=$an_hour*24;
$a_week=$a_day*52;
//$a_month=$a_day*(floor(365/12));

$params--;

if($params==0) return $text;

php return date/time issue [duplicate]

How to get time difference in minutes in PHP
(21 answers)
Closed 9 years ago.
I have a simple function below that gets seconds and returns it like "2 minutes ago", "9 hours ago" etc...
if I pass 1 on 'relativedate()' function it will just return 1 sec and so on. As we all know 60*60*24*7*30 or 18144000sec = 1 month. Therefore if I pass a value of 18144000 on the parameter, it should return 1 month.However, if I pass a value on the parameter lets say 231440000 on relativedate() which should be more than a year, it is returning '13 months' instead of 1 year.
function relativedate($secs) {
$second = 1;
$minute = 60;
$hour = 60*60;
$day = 60*60*24;
$week = 60*60*24*7;
$month = 60*60*24*7*30;
$year = 60*60*24*7*30*365;
if ($secs <= 0) { $output = "now";
}elseif ($secs > $second && $secs < $minute) { $output = round($secs/$second)." second";
}elseif ($secs >= $minute && $secs < $hour) { $output = round($secs/$minute)." minute";
}elseif ($secs >= $hour && $secs < $day) { $output = round($secs/$hour)." hour";
}elseif ($secs >= $day && $secs < $week) { $output = round($secs/$day)." day";
}elseif ($secs >= $week && $secs < $month) { $output = round($secs/$week)." week";
}elseif ($secs >= $month && $secs < $year) { $output = round($secs/$month)." month";
}elseif ($secs >= $year && $secs < $year*10) { $output = round($secs/$year)." year";
}else{ $output = " more than a decade ago"; }
if ($output <> "now"){
$output = (substr($output,0,2)<>"1 ") ? $output."s" : $output;
}
return $output;
}
echo relativedate(60); // 1 minute
Your year calculation is for 365 Months, not 12 months

php function convert seconds to military time? [duplicate]

This question already has answers here:
Convert seconds to Hour:Minute:Second
(30 answers)
Closed 11 months ago.
Is there a built-in php function that converts number of seconds to military time?
So it will take 3600 and output 01:00:00.
Try this:
<?php
$seconds = 3600;
echo sprintf("%02d:%02d:%02d",$seconds/3600,($seconds/60)%60,$seconds%60);
?>
$seconds = 3600;
echo gmdate('H:i:s', $seconds);
xato was nearly there.
With this approach it's a little bit of a cheat but I believe it will behave in exactly the way that you want it to with hours, minutes and seconds.
edit: and the behaviour will be consistent across all servers regardless of their TZ settings
$seconds = 3600;
echo date('H:i:s', $seconds);
There you go. I might have a use for such a function myself sometime, so I wrote that for you.
function time_format($time) {
if($time > 86400) {
return "more than 1 day";
}
$display = '';
if ($time >= 3600) {
$hours = floor($time/3600);
$time = $time%3600;
if($hours <= 9) { $display .= "0"; }
$display .= $hours;
} else {
$display .= "00";
}
$display .= ":";
if($time >= 60) {
$minutes = floor($time/60);
$time = $time%60;
if($minutes <= 9) { $display .= "0"; }
$display .= $minutes;
} else {
$display .= "00";
}
$display .= ":";
if($time > 0) {
$seconds = $time;
if($seconds <= 9) { $display .= "0"; }
$display .= $seconds;
} else {
$display .= "00";
}
return $display;
}
EDIT: seeing bozdoz's answer makes me feel deeply ashamed :(

PHP ceil returning a float

I've created a function to return the difference between two dates
<?php
class days {
function dateDiff($start, $end) {
$start_ts = strtotime($start);
$end_ts = strtotime($end);
$diff = $end_ts - $start_ts;
$diff1 = ceil($diff / 86400);
return $diff1;
}
}
I have this code in the view :
<?php
$a = new days();
$days = $a->dateDiff($v[17], date('Y/m/d'));
if ($days < 30) {
$ds = $days;
$tm = 'days';
} else {
if ($days < 365) {
$ds = $days / 30;
$tm = 'months';
} else {
$ds = $days / 365;
$tm = 'years';
}
}
$v[17] is the date returned from the database to the view.
When I enter for instance an article in august 2011... It will display :
2.9666666666667 months ago
I ask myself ... How this Ceil method could not return an int value as it's supposed to do?
if that's normal, then what's the solution?
Thank you in advance :)
The ceil funciton works just fine when it returns the number of days.
But the problem is here:
if ($days<365){
$ds=$days/30;
$tm='months';
}
You didn't use ceil this time! You should try something like $ds = ceil($days / 30);.
Same thing for the number of years.
It would probably be more precise to use round instead of ceil, so that 32 days don't translate in 2 months:
$days = $a->dateDiff('10 oct 2011',date('Y/m/d'));
if ($days < 30) {
$ds = $days;
$tm = 'day';
}
else {
if ($days < 365){
$ds = round($days / 30);
$tm = 'month';
}
else {
$ds = round($days / 365);
$tm = 'year';
}
}
if ($ds > 1) {
$tm .= 's';
}
echo "$ds $tm"; # => 1 month; or 2 months using ceil function
