A date diff function for PHP before version 5.3.0
Before PHP 5.3.0 there were no date_diff(), then this function can be useful. It returns the difference in days, and you can modify it so it returns hours and seconds as a string i have borrowed it from http://php.net/manual/en/function.date-diff.php. I might some day clean up this function.
<?php
function cc2_date_diff($start, $end) {
$sdate = strtotime($start);
$edate = strtotime($end);
if ($edate < $sdate) {
$sdate_temp = $sdate;
$sdate = $edate;
$edate = $sdate_temp;
}
$time = $edate - $sdate;
$preday[0] = 0;
if($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 $preday[0];
}
