Adding 1:30 And 2:01

[monkeypaw201]

How can I add 1:30 (HH:MM) and 2:01 (HH:MM) ?

 

They are both times to reach a destination, and I want to be able to add them up..

Convert the original time to a timestamp and do:

 

$minute = 60 * 60;

$hour = 60 * 60 * 60;

$newtime = $origtime + ($hour + ($minute * 30));

 

Something like that.

try this

 

<?php
$time1 = "1:30";
$time2 = "2:41";

$t1 = explode(":", $time1);
$t2 = explode(":", $time2);

echo date("G:i:s", mktime($t1[0]+$t2[0], $t1[1]+$t2[1] , 0))."<br />"; // output 4:11:00
?>

Oh woops.  I misunderstood the question actually.  Use craygo's code.  xD  Now I understand what he wanted.

OK for short journey times, Ray, but not for longer ones

 

eg

$time1 = "11:30";

$time2 = "13:41";

 

--> 1:11:00

This should work:

 

<?php
$time1 = '11:30';
$time2 = '13:41';

$t1 = explode(':', $time1);
$t2 = explode(':', $time2);

$hours = $t1[0] + $t2[0];

$minutes = $t1[1] + $t2[1];
while($minutes > 59) {
$hours++;
$minutes = $minutes - 60;
}

echo "$hours hrs, $minutes mins";
?>

 

Edit: Also for times like 26:99 and 432:123. For simple HH:MM (with max 23:59), the while loop can be changed to an if statement (I just realized ).

or, slightly shorter,

 

$time1 = '11:30';
$time2 = '13:41';

list($h1,$m1) = explode (':', $time1);
list($h2,$m2) = explode (':', $time2);

$hours = $h1 + $h2 + floor(($m1+$m2)/60);
$minutes = ($m1 + $m2) % 60;

echo "$hours:$minutes";
