PHP-调整time（）以除以5

date(\'m/d/Y H:i\', time());

date(\'m/d/Y H:i\', time() + 60*60*2);

$time = ceil(time() / 300) * 300;

echo date(\'m/d/Y H:i\', $time);
echo date(\'m/d/Y H:i\', $time + 60 * 60 * 2);

<?php

    $minute = date(\'i\'); 
    $divident = ceil($minute/5); 

    $new_minute = $divident  * 5; 
    $difference = $new_minute - $minute ; 
    date(\'m/d/Y H:i\' ,time() + 60 * $difference   ); // first date 

    date(\'m/d/Y H:i\' ,time() +  $difference * 60 +  (2 * 60 * 60)   ) // second date.
