php中获取时间的几套方法（收集）
1、jddayofweek(cal_to_jd(CAL_GREGORIAN, date('m'), date('d'), date('Y')));此函数返回日期在周几
2、array('Mon'=>'星期一',......);然后直接下标查询
3、根据日期获取周几的自定义函数
function getTime( $val ){if($val>0){$nTime['nDay'] = (int)($val/(3600*24));$nTime['nHour'] = (int)($val%(3600*24)/3600);$nTime['nMin'] = (int)($val%(3600*24)%3600/60);$nTime['nSec'] = (int)($val%(3600*24)%3600%60);}return $nTime ;}function getStrTime( $val ){$aTime = getTime($val);$dtoc = array('nDay'=>'天','nHour'=>'小时','nMin'=>'分','nSec'=>'秒');if( $aTime ){foreach( $aTime as $k=>$v){if($v){$cTime .= $v.$dtoc[$k];}}}else{$cTime = '已结止';}return $cTime;}
