This is correctly working time differentiating function. It's resistant to problems with leap
year and different days of month. Inputs are two timestamps and function returns array with
differences in year, month, day, hour, minute a nd second.
<?php
function date_diff($d1, $d2){
/* compares two timestamps and returns array with differencies (year, month, day, hour, minute,
second)
*/
//check higher timestamp and switch if neccessary
if ($d1 < $d2){
$temp = $d2;
$d2 = $d1;
$d1 = $temp;
}
else {
$temp = $d1; //temp can be used for day count if required
}
$d1 = date_parse(date("Y-m-d H:i:s",$d1));
$d2 = date_parse(date("Y-m-d H:i:s",$d2));
//seconds
if ($d1['second'] >= $d2['second']){
$diff['second'] = $d1['second'] - $d2['second'];
}
else {
$d1['minute']--;
$diff['second'] = 60-$d2['second']+$d1['second'];
}
//minutes
if ($d1['minute'] >= $d2['minute']){
$diff['minute'] = $d1['minute'] - $d2['minute'];
}
else {
$d1['hour']--;
$diff['minute'] = 60-$d2['minute']+$d1['minute'];
}
//hours
if ($d1['hour'] >= $d2['hour']){
$diff['hour'] = $d1['hour'] - $d2['hour'];
}
else {
$d1['day']--;
$diff['hour'] = 24-$d2['hour']+$d1['hour'];
}
//days
if ($d1['day'] >= $d2['day']){
$diff['day'] = $d1['day'] - $d2['day'];
}
else {
$d1['month']--;
$diff['day'] = date("t",$temp)-$d2['day']+$d1['day'];
}
//months
if ($d1['month'] >= $d2['month']){
$diff['month'] = $d1['month'] - $d2['month'];
}
else {
$d1['year']--;
$diff['month'] = 12-$d2['month']+$d1['month'];
}
//years
$diff['year'] = $d1['year'] - $d2['year'];
return $diff;
