PHP How to find the time elapsed since a date time? [duplicate]

Answer 1

Here I am using custom function for finding the time elapsed since a date time.

echo Datetodays('2013-7-26 17:01:10');

function Datetodays($d) {

        $date_start = $d;
        $date_end = date('Y-m-d H:i:s');

        define('SECOND', 1);
        define('MINUTE', SECOND * 60);
        define('HOUR', MINUTE * 60);
        define('DAY', HOUR * 24);
        define('WEEK', DAY * 7);

        $t1 = strtotime($date_start);
        $t2 = strtotime($date_end);
        if ($t1 > $t2) {
            $diffrence = $t1 - $t2;
        } else {
            $diffrence = $t2 - $t1;
        }

        //echo "
".$date_end."  ".$date_start."  ".$diffrence;
        $results['major'] = array(); // whole number representing larger number in date time relationship
        $results1 = array();
        $string = '';

        $results['major']['weeks'] = floor($diffrence / WEEK);
        $results['major']['days'] = floor($diffrence / DAY);
        $results['major']['hours'] = floor($diffrence / HOUR);
        $results['major']['minutes'] = floor($diffrence / MINUTE);
        $results['major']['seconds'] = floor($diffrence / SECOND);

        //print_r($results);
        // Logic:
        // Step 1: Take the major result and transform it into raw seconds (it will be less the number of seconds of the difference)
        // ex: $result = ($results['major']['weeks']*WEEK)
        // Step 2: Subtract smaller number (the result) from the difference (total time)
        // ex: $minor_result = $difference - $result
        // Step 3: Take the resulting time in seconds and convert it to the minor format
        // ex: floor($minor_result/DAY)

        $results1['weeks'] = floor($diffrence / WEEK);
        $results1['days'] = floor((($diffrence - ($results['major']['weeks'] * WEEK)) / DAY));
        $results1['hours'] = floor((($diffrence - ($results['major']['days'] * DAY)) / HOUR));
        $results1['minutes'] = floor((($diffrence - ($results['major']['hours'] * HOUR)) / MINUTE));
        $results1['seconds'] = floor((($diffrence - ($results['major']['minutes'] * MINUTE)) / SECOND));

        //print_r($results1);

        if ($results1['weeks'] != 0 && $results1['days'] == 0) {
            if ($results1['weeks'] == 1) {
                $string = $results1['weeks'] . ' week ago';
            } else {
                if ($results1['weeks'] == 2) {
                    $string = $results1['weeks'] . ' weeks ago';
                } else {
                    $string = '2 weeks ago';
                }
