How do I use date_diff in my code (both codes are included, mine and the example function) I need process.php

justino garcia <jgarciaitlist@xxxxxxxxx> · Mon, 3 May 2010 00:23:28 -0400

HOw would I use this function below, from this url
http://php.net/manual/en/function.date-diff.php
I need to output the subject, date, and the final answer to the calcuation
of the time difference (say from e.g. 10:00 AM to 12:00 PM) . Getting total
time wrked on at a job site, doing helpdesk. I am doing this for me to send
a preformated email to acounting, it will help since I am busy at work and
suck at counting time worked due to my adhd and dyslxia.
Thanks

This function calculates the difference up to the second.

<?php

function date_diff($start, $end="NOW")
{
        $sdate = strtotime($start);
        $edate = strtotime($end);

        $time = $edate - $sdate;
        if($time>=0 && $time<=59) {
                // Seconds
                $timeshift = $time.' seconds ';

        } elseif($time>=60 && $time<=3599) {
                // Minutes + Seconds
                $pmin = ($edate - $sdate) / 60;
                $premin = explode('.', $pmin);

                $presec = $pmin-$premin[0];
                $sec = $presec*60;

                $timeshift = $premin[0].' min '.round($sec,0).' sec ';

        } elseif($time>=3600 && $time<=86399) {
                // Hours + Minutes
                $phour = ($edate - $sdate) / 3600;
                $prehour = explode('.',$phour);

                $premin = $phour-$prehour[0];
                $min = explode('.',$premin*60);

                $presec = '0.'.$min[1];
                $sec = $presec*60;

                $timeshift = $prehour[0].' hrs '.$min[0].' min '.round($sec,
0).' sec ';

        } elseif($time>=86400) {
                // Days + Hours + Minutes
                $pday = ($edate - $sdate) / 86400;
                $preday = explode('.',$pday);

                $phour = $pday-$preday[0];
                $prehour = explode('.',$phour*24);

                $premin = ($phour*24)-$prehour[0];
                $min = explode('.',$premin*60);

                $presec = '0.'.$min[1];
                $sec = $presec*60;

                $timeshift = $preday[0].' days '.$prehour[0].' hrs '.$min[0
].' min '.round($sec,0).' sec ';

        }
        return $timeshift;
}

// EXAMPLE:

$start_date = 2010-03-15 13:00:00
$end_date = 2010-03-17 09:36:15

echo date_diff($start_date, $end_date);

?>
