$since_start = $start_date->diff(new DateTime(date("Y-m-d h:i:s")));//2018-04-18 04:10 PM
if( intval($since_start->format('%Y') ) >= 1){

}
else if(intval($since_start->format('%m')) >= 1){
$timeago = $since_start->format('%m months ');
}

}
else if(intval($since_start->format('%i')) >= 1){
$timeago = $since_start->format('%i minutes ');
}
else if(intval($since_start->format('%s')) >= 1){
$timeago = $since_start->format('%s seconds ');

}
echo timeAgo('2018-04-18 04:30 PM');
?>
I am getting result like this
12 hours
My Expected output is

Your just give the now DateTime only. You don't want to declare the time format. And you just use this time zone only date_default_timezone_set('Asia/Kolkata');. Here is code:
date_default_timezone_set('Asia/Kolkata');
function timeAgo($logintime)
{
$start_date = new DateTime($logintime);
$since_start = new DateTime();
$interval = $since_start->diff($start_date);
$timeago = $interval->format("%a days, %h hours, %i minutes, %s seconds");
if($since_start < $start_date){
return $timeago. ' ago';
}else{
return 'This Event Passed';
}
}
echo timeAgo('2018-04-19 05:50 PM');
Out put:
1 days, 0 hours, 56 minutes, 28 seconds ago
