Question

I have searched,i had too many trial/errors but no luck.So here it goes:

I want to find out how many second have been elapsed since a date from Mysql entry which was inserted with NOW() and the current date in the format date("Y.m.d H:i:s").Here is my php function(taken from a user posted @stackoverflow).

function multipost(){
global $dbh;
$ip= $_SERVER['REMOTE_ADDR']; 

$sql = "select * from  table where ip='$ipa' order by date_time desc limit 1";

foreach ($dbh->query($sql) as $row) {
    $timeFirst=$row['date_time'];
    $timeSecond=date("Y.m.d H:i:s");
    $differenceInSeconds = $timeSecond-$timeFirst;
    echo $differenceInSeconds;
}

I have also tried strtotime($row['date_time'];) but no luck.
Any help?
Thanks in advance.

function secDifference($date,$time){
    $dateVals = explode("-",$date);
    $timeUnix = 0;
    if($time == 0){
        $timeUnix = date("U",mktime(0,0,0,$dateVals[1],$dateVals[2],$dateVals[0]));
    }
    else{
        $tempVals = explode(" ",$dateVals[2]);
        $dateVals[2] = $tempVals[0];
        $timeVals = explode(":",$tempVals[1]);
        $timeUnix = date("U",mktime($timeVals[0],$timeVals[1],$timeVals[2],$dateVals[1],$dateVals[2],$dateVals[0]));
    }
    return (date("U")-$timeUnix);
}

Copy this function.
To get difference of DATE and NOW:

secDifference("12/03/1993");

To get difference of DATE TIME and NOW:

secDifference("12/03/1993 14:54:32",1);

Hope it helps.
