PHP 日期操作小结

最近项目中应用PHP日期处理较多，顺便记录一下。

<?php //PHP获得当前日期的前一天和后一天echo date('Y-m-d',time()-86400);echo date('Y-m-d',time()+86400);//2011-07-09 2011-07-11//-------------------------------------- 分割线 ------------------------------------//PHP获得明天、上个月、明年$tomorrow  = date("Y-m-d", mktime(0, 0, 0, date("m")  , date("d")+1, date("Y"))); $lastmonth = date("Y-m-d", mktime(0, 0, 0, date("m")-1, date("d"),   date("Y")));$nextyear  = date("Y-m-d", mktime(0, 0, 0, date("m"),   date("d"),   date("Y")+1));echo $tomorrow.' '.$lastmonth.' '.$nextyear;//2011-07-11 2011-06-10 2012-07-10//-------------------------------------- 分割线 ------------------------------------//PHP获得指定日期所在星期的第一天和最后一天function getWeekDay($date){    $lastday = date("Y-m-d",strtotime("$date Sunday"));    $firstday = date("Y-m-d",strtotime("$lastday -6 days"));    return array($firstday,$lastday);}print_r(getWeekDay("2011-07-10"));/** * Array * 	( *   	[0] => 2011-07-04 *  	[1] => 2011-07-10 *	) *///-------------------------------------- 分割线 -------------------------------//PHP获得指定日期所在月的第一天和最后一天function getMonthDay($date){    $firstday = date("Y-m-01",strtotime($date));    $lastday = date("Y-m-d",strtotime("$firstday +1 month -1 day"));    return array($firstday,$lastday);}print_r(getMonthDay("2011-07-10"));/** * Array * 	( *   	[0] => 2011-07-01 *  	[1] => 2011-07-31 *	) */
