So I needed to know how many days there were between to UNIX timestamp values, and here is the code for those who may also need it.
function dateDiffUnix($startDate) {
echo ‘$start_date ‘.$startDate.’ – ‘.date(‘Y m d G:i:s’, $startDate).’<br />’;
$endDate = time();
echo ‘$end_date ‘.$endDate.’ – ‘.date(‘Y m d G:i:s’, $endDate).’<br />’;
$difference = $endDate – $startDate;
return round($difference / 86400);
}
echo ‘Unix date difference: ‘.dateDiffUnix(“1292479971″); // start time
In my case the start date will be passed in as a value from the database, but for this sample, a hard-coded value will suffice.
