PHP 获取指定日期的星期方法如下:
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
?>
date第二个参数应该是时间戳
mktime函数生成时间戳,原型如下:int mktime ([ int $hour [, int $minute [, int $second [, int $month [, int $day [, int $year [, int $is_dst ]]]]]]] )
echo "星期".$weekarray[date("w",mktime(0,0,0,3,12,2010))];
还可参考strtotime()函数
$weekarray=array("日","一","二","三","四","五","六");
echo "星期".$weekarray[date('w',"20102010-3-12")];
你写的没错,再调调。
echo date('w',strtotime('2010-03-10'));
