I've been looking for a function, which could count years, months, days, hours and minutes
since some date till now, but I couldn't find any. So I wrote one, using the date().
Seems to work OK.
<?php
function from2now($year, $month, $day, $hour, $minute) {
// common
$todayMonth = date(n); // current month
$todayDay = date(j); // current day
$todayHour = date(G); // current hour
$todayMinute = date(i); // current minute
/*
$year - given start year
$month - given start month
$day - given start day
$hour - given start hour
$minute - given start minute
*/
### count years
$monthday = date(nj);
$link = $month.$day;
$datepoint = $link;
if ($monthday < $datepoint) $years = date(Y) - $year - 1;
else $years = date(Y) - $year;
// proper form of words (year, years)
if ($years < 1) $yearWord = '';
elseif ($years == 1) $yearWord = 'year';
elseif ($years > 1) $yearWord = 'years';
### count months
if ($todayMonth > $month) {
if ($todayDay < $day) $months = $todayMonth - $month -1;
else $months = $todayMonth - $month;
}
else {
$between = $month - $todayMonth;
$plus = 12 - $month;
if ($todayDay < $day) $months = $month + $plus - $between -1;
else $months = $month + $plus - $between;
}
// again, proper form of words (month, months)
if ($months == 1) $monthWord = 'month';
elseif ($months > 1) $monthWord = 'months';
### count days
if ($todayDay > $day) {
if ($todayHour < $hour) $days = $todayDay - $day -1;
else $days = $todayDay - $day;
}
else {
$between = $day - $todayDay;
$daysToEndOfMonth = date(t) - $day;
if (date(t) == 28) $plus = $daysToEndOfMonth;
if (date(t) == 29) $plus = $daysToEndOfMonth;
if (date(t) == 30) $plus = $daysToEndOfMonth;
if (date(t) == 31) $plus = $daysToEndOfMonth;
if ($todayHour < $hour) $days = $day + $plus - $between - 1;
else $days = $day + $plus - $between;
}
// words...
if ($days == 1) $dayWord = 'day';
else $dayWord = 'days';
### count hours
if ($todayHour > $hour) {
if ($todayMinute < $minute) $hours = $todayHour - $hour - 1;
else $hours = $todayHour - $hour;
}
else {
$between = $hour - $todayHour;
$plus = 24 - $hour;
if ($todayMinute < $minute) $hours = $hour + $plus - $between - 1;
else $hours = $hour + $plus - $between;
}
// ...
if ($hours == 1) $hourWord = 'hour';
if ($hours > 1) $hourWord = 'hours';
### count minutes
if ($todayMinute > $minute) {
$minutes = $todayMinute - $minute;
}
else {
$between = $minute - $todayMinute;
$plus = 60 - $minute;
$minutes = $minute + $plus - $between;
}
if ($minutes == 60) $minutes = 0;
if ($minutes == 1) $minuteWord = 'minute';
elseif ($minutes > 1) $minuteWord = 'minutes';
if ($years == 0) { $years = ''; $yearWord = ''; }
if ($months == 0) { $months = ''; $monthWord = ''; }
if ($days == 0) { $days = ''; $dayWord = ''; }
if ($hours == 0) { $hours = ''; $hourWord = ''; }
if ($minutes == 0) { $minutes = ''; $minuteWord = ''; }
### echo result
echo $years.' '.$yearWord.' '.$months.' '.$monthWord.'
'.$days.' '.$dayWord.' '.$hours.' '.$hourWord.'
'.$minutes.' '.$minuteWord.'';
}
?>
