A simple way to get the time lag (format: <hours>.<one-hundredth of one hour>).

Hier ein einfacher Weg zur Bestimmung der Zeitdifferenz (Format: <Stunden>.<hundertstel Stunde>).

<?php

function GetDeltaTime($dtTime1$dtTime2)
{
 
$nUXDate1 strtotime($dtTime1->format("Y-m-d H:i:s"));
 
$nUXDate2 strtotime($dtTime2->format("Y-m-d H:i:s"));

 
$nUXDelta $nUXDate1 $nUXDate2;
 
$strDeltaTime "" $nUXDelta/60/60// sec -> hour
           
 
$nPos strpos($strDeltaTime".");
  if (
nPos !== false)
   
$strDeltaTime substr($strDeltaTime0$nPos 3);

  return 
$strDeltaTime;
}

This is a very simple function to calculate the difference between two datetime values, returning the result in seconds. To convert to minutes, just divide the result by 60. In hours, by 3600 and so on.

Enjoy.

<?php
function time_diff($dt1,$dt2){
   
$y1 substr($dt1,0,4);
   
$m1 substr($dt1,5,2);
   
$d1 substr($dt1,8,2);
   
$h1 substr($dt1,11,2);
   
$i1 substr($dt1,14,2);
   
$s1 substr($dt1,17,2);   

   
$y2 substr($dt2,0,4);
   
$m2 substr($dt2,5,2);
   
$d2 substr($dt2,8,2);
   
$h2 substr($dt2,11,2);
   
$i2 substr($dt2,14,2);
   
$s2 substr($dt2,17,2);   

   
$r1=date('U',mktime($h1,$i1,$s1,$m1,$d1,$y1));
   
$r2=date('U',mktime($h2,$i2,$s2,$m2,$d2,$y2));
    return (
$r1-$r2);

Here is how I solved the problem of missing date_diff function with php versions below 5.3.0
The function accepts two dates in string format (recognized by strtotime() hopefully), and returns the date difference in an array with the years as first element, respectively months as second, and days as last element.
It should be working in all cases, and seems to behave properly when moving through February.

<?php
       
function dateDifference($startDate$endDate)
        {
           
$startDate strtotime($startDate);
           
$endDate strtotime($endDate);
            if (
$startDate === false || $startDate || $endDate === false || $endDate || $startDate $endDate)
                return 
false;
               
           
$years date('Y'$endDate) - date('Y'$startDate);
           
           
$endMonth date('m'$endDate);
           
$startMonth date('m'$startDate);
           
           
// Calculate months
           
$months $endMonth $startMonth;
            if (
$months <= 0)  {
               
$months += 12;
               
$years--;
            }
            if (
$years 0)
                return 
false;
           
           
// Calculate the days 
                       
$offsets = array();
                        if (
$years 0)
                           
$offsets[] = $years . (($years == 1) ? ' year' ' years');
                        if (
$months 0)
                           
$offsets[] = $months . (($months == 1) ? ' month' ' months');
                       
$offsets count($offsets) > '+' implode(' '$offsets) : 'now';

                       
$days $endDate strtotime($offsets$startDate);
                       
$days date('z'$days);   
                       
            return array(
$years$months$days);
        }

Even the top rated comment here, Sergio Abreu's, doesn't treat leap years entirely correctly. It should work between 1901 and 2099, but outside that it'll be a little off.

If you want to find out the number of days between two dates, use below. You can change to a different unit from that. It looks a little insane, but keep in mind the full set of rules for leap years:

If the year is divisible by 4, it's a leap year...
 - unless the year is divisible by 100, then it isn't...
 - - unless the year is divisible by 400, then it really is.

So in the functions below, we find the total numbers of days in full years since the mythical 1/1/0001, then add the number of days before the current one in the year passed. Do this for each date, then return the absolute value of the difference.

function days_diff($d1, $d2) {
    $x1 = days($d1);
    $x2 = days($d2);
   
    if ($x1 && $x2) {
        return abs($x1 - $x2);
    }
}

function days($x) {
    if (get_class($x) != 'DateTime') {
        return false;
    }
   
    $y = $x->format('Y') - 1;
    $days = $y * 365;
    $z = (int)($y / 4);
    $days += $z;
    $z = (int)($y / 100);
    $days -= $z;
    $z = (int)($y / 400);
    $days += $z;
    $days += $x->format('z');

    return $days;
}

My simple function to count up the number of weekdays between the dates (inclusive for both ends), one can add a holidays between the dates to take them into account as well as the weekends, the weekend days could also be changed.

   $full_weeks_count = floor($total_days_count/7);
   $weekend_days_count = $full_weeks_count*count($__weekend_days);
   $days_left_uncovered = $total_days_count - $full_weeks_count*7;
   for($i = 0; $i < $days_left_uncovered; $i++) {
      $date_to_check = $i ? strtotime("+{$i} day", $__date_from) : $__date_from;
      if(in_array(date('N', $date_to_check), $__weekend_days)) {
         $weekend_days_count++;
      }
   }
   $week_days_count = $total_days_count - $weekend_days_count - count($__holidays_between);

I do not have much programming in php and I hope I can help those that I want to do is that when entering in the form the date 1 and the date2 I calculate if between those two dates if they have passed 5 or more years and I add 3 more days taking As reference date 2, I do not know if I understand.

To see a theoretical example date = 10/01/2012 date2 = 23/07/2017

Between these two dates have passed 5 years, 6 months, and 13 days elapsed

Knowing this my serious conditional

If they are equal or more than 5 years but less than 10 years will be added 3 days
If they are equal or more than 10 years but less than 15 years will be added 6 days
If they are equal or more than 15 years but less than 20 years will be added 9 days
If they are equal to or more than 20 years will be added 12 days

Then having the conditionals

For this example would be case as it is greater than 5 years the result that I should show taking in days, having as date of departure the date2 = 23/07/2017 and to this date it is added 30 days that would be a constant and depending on the Years as the example happens 5 years would be: date2 = 23/07/2017 + 30 days = 08/30/2017 + 3 days
= End date to show = result = 02/09/2017.

But I still think how to do it if you can guide me I would appreciate a world, and everything should show without pressing buttons, if I press a button would be like to store in the database only the results otenidos as date1 date2 and result

<? Php
    
// $ date1 = $ _ POST ["date1"]; // this will be the first date or date of entry
// $ date2 = $ _ POST ["date2"]; // this will be the date with which you will calculate
    
// $ difference = $ date2 - $ date1;

// if ($ difference <= 5)
{
    // echo "number of days that correspond to it [". $ Date2 + 30 + 3. "].";

//} else {

// ($ difference <= 5)

{
// echo "number of days corresponding to it [" $ date2 + 30 "].";

}

 ?>
