How to calculate new dates

[Nuker]

I need calculate the future... mmm

I need add to actual time 300 seconds or 1000 or 3000 seconds and know the future time...

For example:
If the actual time is:

Day 1
Month 9
Year 07
Hour 01
Minuts 54
Seconds 17

add 60 seconds ...

Day 1
Month 9
Year 07
Hour 01
Minuts 55 ----> +60 seconds, no more 54.. its 55 now
Seconds 17

______________________________

I think do that...

PHP Code:

<?PHP
$more_seconds = 60;

$date = date("d");
$month = date("m");
$year = date("y");
$hours = date("H");
$minuts =  date("i");
$seconds = date("s");

echo "day: $date, month: $month, year: $year, Hour: $hours:$minuts:$seconds";

$seconds = $seconds + $more_seconds;

while($seconds > 60){
$seconds = $seconds - 60;
$minuts = $minuts + 1;
}

while($minuts > 60){
$minuts = $minuts - 60;
$hours = $hours + 1;
}

while($hours > 24){
$hours = $hours - 24;
$date = $date + 1;
}

$ok = false;
while($ok == false){

if ($month == 1 OR $month == 3 OR $month == 5 OR $month == 7 OR $month == 8 OR $month == 10 OR $mont == 12){
if ($date > 31){
$date = $date - 31;
$month = $month + 1;
}
else
{
$ok = true;
}

}
if ($month == 4 OR $month == 6 OR $month == 9 OR $month == 11){
if ($date > 30){
$date = $date - 30;
$month = $month + 1;
}
else
{
$ok = true;
}

}

if ($month == 02){
if ($date > 28){
$date = $date - 28;
$month = $month + 1;
}
else
{
$ok = true;
}

}

if ($month > 12){
$month = $month - 12;
$year = $year + 1;
}

} //end $ok == false

echo "day: $date, month: $month, year: $year, Hour: $hours:$minuts:$seconds";

?>

But that script i make... i think have a error... "leap year years" in spanish "aņos biciestos"... anything can help me?

The easiest way in PHP is to convert your date into a timestamp (look up the strtotime function), then add the number of seconds to the timestamp. Then, you can convert your timestamp back into a date string.

Timestamps are calculated by the number of seconds from midnight on January 1, 1970. Therefore, a timestamp of "60" would be 00:01:00 on Jan. 1, 1970. If you add your current timestamp (which you can get using the Now() function in PHP) plus the number of seconds you want to add (300, 1000, or 3000), you'll get the correct time.

Hello, i have another problem

In a game, i send a warrior to attack other player, this warrior travell to the enemy city and he have in the data base the time in "hours" "seconds" minuts date month and years to travell

I put a button to abort the travell, in that link i calculate.. the time in the data base of the warrior to finish the travell, minus the current time, the result i add to the current time, and know i have the new time to he must wait to travell from the current position to his "city"


The problem its... the result of all operations.. equal to the first time to he travell to the enemys point :S...

if anything cant understand me pls say.. i post better, sorry my bad english

i post the code, if any can show the error ... :/

PHP Code:

$sql=mysql_query("SELECT userid, victoria, dia, mes, anio, horas, minutos, segundos FROM kw_users WHERE userid = $userid",$con);
while($row = mysql_fetch_array($sql))
  {
    if ($row["victoria"] == "llendo"){
    
    $date = $row["dia"];
    $month = $row["mes"];
    $year = $row["anio"];
    $hours = $row["horas"];
    $minuts = $row["minutos"];
    $seconds = $row["segundos"];

$futuro = mktime($hours, $minuts, $seconds, $month, $date, $year) - time();

$futuro = time() + $futuro;

$date = date("d",$futuro);
$month = date("m",$futuro);
$year = date("y",$futuro);
$hours = date("H",$futuro);
$minuts =  date("i",$futuro);
$seconds = date("s",$futuro);

mysql_query("UPDATE kw_users SET dia = $date WHERE userid = $userid");
mysql_query("UPDATE kw_users SET mes = $month WHERE userid = $userid");
mysql_query("UPDATE kw_users SET anio = $year WHERE userid = $userid");
mysql_query("UPDATE kw_users SET horas = $hours WHERE userid = $userid");
mysql_query("UPDATE kw_users SET minutos = $minuts WHERE userid = $userid");
mysql_query("UPDATE kw_users SET segundos = $seconds WHERE userid = $userid");
  }

To help yourself debug the issue, try echoing some of the values that you're coming up with before actually committing anything to the database. For instance, I would recommend echoing each of your variables as you're working. Something like:

$sql=mysql_query("SELECT userid, victoria, dia, mes, anio, horas, minutos, segundos FROM kw_users WHERE userid = $userid",$con);
while($row = mysql_fetch_array($sql))
  {
    if ($row["victoria"] == "llendo"){
    
    $date = $row["dia"];
    $month = $row["mes"];
    $year = $row["anio"];
    $hours = $row["horas"];
    $minuts = $row["minutos"];
    $seconds = $row["segundos"];

echo "<div>$date<br />$month<br />$year<br />$hours<br />$minuts<br />$seconds</div>";

$futuro = mktime($hours, $minuts, $seconds, $month, $date, $year) - time();

echo "<div>$futuro</div>";

$futuro = time() + $futuro;

echo "<div>$futuro</div>"

$date = date("d",$futuro);
$month = date("m",$futuro);
$year = date("y",$futuro);
$hours = date("H",$futuro);
$minuts =  date("i",$futuro);
$seconds = date("s",$futuro);

echo "<div>$date<br />$month<br />$year<br />$hours<br />$minuts<br />$seconds</div>";
}

yesssssss
tyyyyyyyyyy

now i know the problem and fix it xD

the problem is in the pluss and minuss xDDDD

now work perfect! ^^

PHP Code:

    $date = $row["dia"];
    $month = $row["mes"];
    $year = $row["anio"];
    $hours = $row["horas"];
    $minuts = $row["minutos"];
    $seconds = $row["segundos"];
    $dateb = $row["diab"];
    $monthb = $row["mesb"];
    $yearb = $row["aniob"];
    $hoursb = $row["horasb"];
    $minutsb = $row["minutosb"];
    $secondsb = $row["segundosb"];
    
$A_C = mktime($hours, $minuts, $seconds, $month, $date, $year) - time();
$B_A = mktime($hoursb, $minutsb, $secondsb, $monthb, $dateb, $yearb) - mktime($hours, $minuts, $seconds, $month, $date, $year);
$futuro = $B_A - $A_C;
$futuro = time() + $futuro;
$date = date("d",$futuro);
$month = date("m",$futuro);
$year = date("y",$futuro);
$hours = date("H",$futuro);
$minuts =  date("i",$futuro);
$seconds = date("s",$futuro);
