We can also get the submitted datetime (e.g. 2009-11-06 07:03:41) using the following:





<?php


$DateOfRequest = date("Y-m-d H:i:s", strtotime($_REQUEST["DateOfRequest"]));


?>





Or another good example of getting DateTime:





<?php


$DateOfRequest = date("Y-m-d H:i:s", mktime($_REQUEST["Hour"],$_REQUEST["Min"],$_REQUEST


["Sec"],$_REQUEST["Month"],$_REQUEST["Day"],$_REQUEST["Year"]));            


?>

Should you want to convert between HH:MM:SS and plain seconds like in MySQL, these functions should do the trick:





<?php


function time_to_sec($time) {


    $hours = substr($time, 0, -6);


    $minutes = substr($time, -5, 2);


    $seconds = substr($time, -2);





    return $hours * 3600 + $minutes * 60 + $seconds;


}





function sec_to_time($seconds) {


    $hours = floor($seconds / 3600);


    $minutes = floor($seconds % 3600 / 60);


    $seconds = $seconds % 60;





    return sprintf("%d:%02d:%02d", $hours, $minutes, $seconds);


}


?>
