PHP - Convert this into hours

Question

I wanted to convert this into hours:

 <?php
( strtotime('12:45:00') - strtotime('11:00:00') ) / 60 (This is for minutes)
?>

Answer 1

You can convert minutes to hour using following function:

<?php

function convertToHoursMins($time, $format = '%02d:%02d') {
   if ($time < 1) {
      return;
   }
   $hours = floor($time / 60);
   $minutes = ($time % 60);
   return sprintf($format, $hours, $minutes);
}

echo convertToHoursMins(250, '%02d hours %02d minutes');

Although I'm not sure whether I understand you right, here's an example:

    <?php

        $resultM = ( strtotime('12:45:00') - strtotime('11:00:00') ) / 60;           // (This is for minutes)
        $resultH = ( strtotime('12:45:00') - strtotime('11:00:00') ) / 3600;         // (This is for hours)
        $resultH1 = floor(( strtotime('12:45:00') - strtotime('11:00:00') ) / 3600); // (This is for hours)

        echo "Minutes=$resultM<br />Hours(float)=$resultH<br />Houres(floor)=$resultH1<br />";

    ?>

Answer 3

Try this example. Positive and Negative answer will depends on date provided first in date_diff function.

$date1 = date_create("12:45:00");
$date2 = date_create("11:00:00");

$diff=date_diff($date1,$date2);
echo "Difference in Hours\n";
echo $diff->format("%R%H hours")."\n";
echo "Difference in Minutes\n";
echo $diff->format("%R%i minutes");

Another Example

$date1 = new DateTime("11:00:00");
