function datezhuanhuan($dateparams){$ccc=strtotime($dateparams);$date=date(‘y-m-d');$bjtime=date(‘y-m-d',$ccc);if($date==$bjtime){$sbjtime=date(‘y-m-d h:i:s',$ccc);echo substr($sbjtime,11,5);}else{$sbjtime=date(‘y-m-d h:i:s',$ccc);return substr($sbjtime,5,5);}}
另一种+8小时的算法：
$bj_time = date (y-m-d h:i:s , mktime(gmdate('h')+8,gmdate('i'),gmdate('s'),gmdate('m'),gmdate('d'),gmdate('y')));
