php时间如何转化为星期几
转换方法:1、使用date()和“strtotime(指定日期)”将日期转换成表示星期的数字;2、定义“array("日","一","二","三","四","五","六")”数组;3、将数字作为下标,在数组中取出对应的星期值即可。
本教程操作环境:windows7系统、PHP7.1版,DELL G3电脑
function get_week($date){ //强制转换日期格式 $date_str=date('Y-m-d',strtotime($date)); //封装成数组 $arr=explode("-", $date_str); //参数赋值 //年 $year=$arr[0]; //月,输出2位整型,不够2位右对齐 $month=sprintf('%02d',$arr[1]); //日,输出2位整型,不够2位右对齐 $day=sprintf('%02d',$arr[2]); //时分秒默认赋值为0; $hour = $minute = $second = 0; //转换成时间戳 $strap = mktime($hour,$minute,$second,$month,$day,$year); //获取数字型星期几 $number_wk=date("w",$strap); //自定义星期数组 $weekArr=array("星期日","星期一","星期二","星期三","星期四","星期五","星期六"); //获取数字对应的星期 return $weekArr[$number_wk]; } //测试 /*$date="2016-08-21"; echo get_week($date); */ // echo '<pre>'; foreach ($all as $k => $v) { $arr[$k]['time'] = $v['time']; $arr[$k]['oprate'] = $v['oprate']; $arr[$k]['record'] = $v['record']; $arr[$k]['xq'] = get_week($v['time']); // var_dump($v); }
