Datetime til timestamp

Ved godt der findes UNIX_TIMESTAMP direkte i sql'en - men findes der ikke en php funktion til det?

www.php.net/mktime

Jep, og så denne her funktion som er sakset fra et af jakoba's svar et sted:

//make timestamp
if (ereg('^([0-9]+)-([0-9]+)-([0-9]+) ([0-9]+):([0-9]+):([0-9]+)$',$lastedit,$reg))
{
$timestamp = mktime($reg[4], $reg[5], $reg[6], $reg[2], $reg[3], $reg[1]);
}
//to days, hours, min etc...
$totalminutes = floor($totalseconds/60);
$seconds = $totalseconds % 60;

$totalhours = floor($totalminutes/60);
$minutes = $totalminutes%60;

$totaldays = floor($totalhours/24);
$hours = $totalhours%24;
   
echo ($totaldays ." dage, " .$hours ." timer, " .$minutes ." min, og " .$seconds ." sek.");

Og så lige helt rigtigt:

//make timestamp
if (ereg('^([0-9]+)-([0-9]+)-([0-9]+) ([0-9]+):([0-9]+):([0-9]+)$',$lastedit,$reg))
{
$timestamp = mktime($reg[4], $reg[5], $reg[6], $reg[2], $reg[3], $reg[1]);
}
//to days, hours, min etc...
$totalminutes = floor($timestamp/60);
$seconds = $totalseconds % 60;

$totalhours = floor($totalminutes/60);
$minutes = $totalminutes%60;

$totaldays = floor($totalhours/24);
$hours = $totalhours%24;
 
echo ($totaldays ." dage, " .$hours ." timer, " .$minutes ." min, og " .$seconds ." sek.");
