开发过程中,常用日期处理函数,时间戳处理函数等,如下讲解: <?php echo date('Y-m-d h:i:s',time()); //运行结果(年月日时分秒,“-”间隔):2014-09-12 06:28:32 echo date('Y-m-d',time()); //运行结果(年月日,“-”间隔):2014-09-12 echo date('Y-m-d',strtotime(date('Y-m-d', time()-86400))); //运行结果(当前日期前一天的年月日,“-”间隔):2014-09-11 echo date('Ymd',time()); //运行结果(年月日,无间隔):20140912 echo date('m-d',time()); //运行结果(月日,“-”间隔):09-12 echo str_replace("-","月",date('m-d',time()-date('w',time())*86400))."日"; //运行结果(月日,汉字显示间隔):09月12日 echo date('w',time()); //运行结果(星期几):5 echo time(); //运行结果(当前日期时间的秒数):1410503809 echo strtotime(date('Y-m-d',time())); //运行结果(当前日期秒数,具体到天):1410503809 echo date('Y-m-d',strtotime(date('Y-m-d', time()))-date('w',strtotime(date('Y-m-d', time())))*86400); //运行结果(当前日期所属自然周的起始日期即周日的日期,具体到天,“-”间隔):2014-09-07
//php获取今日开始时间戳和结束时间戳 $beginToday=mktime(0,0,0,date('m'),date('d'),date('Y')); $endToday=mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1; //php获取昨日起始时间戳和结束时间戳 $beginYesterday=mktime(0,0,0,date('m'),date('d')-1,date('Y')); $endYesterday=mktime(0,0,0,date('m'),date('d'),date('Y'))-1; //php获取上周起始时间戳和结束时间戳 $beginLastweek=mktime(0,0,0,date('m'),date('d')-date('w')+1-7,date('Y')); $endLastweek=mktime(23,59,59,date('m'),date('d')-date('w')+7-7,date('Y')); //php获取本月起始时间戳和结束时间戳 $beginThismonth=mktime(0,0,0,date('m'),1,date('Y')); $endThismonth=mktime(23,59,59,date('m'),date('t'),date('Y'));
