I couldn't find any correct date differentiate function anywhere so I wrote this one which
works correctly. It's fully resistant to all troubles with different day count of the month or
leap year.
Input must be two timestamps and output is associative array with year, month, day, hour, minute,
second items.
It can be used for exact age or similar issues.
<?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;
}
$born_date = mktime(6,30,0,7,24,2008);
$date_diff_array = date_diff($born_date, time());
print_r($date_diff_array);
