PHP 获取指定日期的星期方法如下
<?php header("Content-type: text/html; charset=utf-8"); //获取星期方法 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 $date="2015-12-10"; echo get_week($date); //星期四 ?>
