php日期转礼拜

php怎么实现日期转礼拜几？

使用php得到指定日期对应的星期几或周几

获取英文星期几

date("l"); //data就可以获取英文的星期比如Sunday
date("w"); //这个可以获取数字星期比如123，注意0是星期日

获取中文星期几

$weekarray = array("日", "一", "二", "三", "四", "五", "六"); //先定义一个数组
echo "星期" . $weekarray[date("w",time())];

获取指定日期是

$weekarray=array("日","一","二","三","四","五","六");
echo "星期".$weekarray[date("w",strtotime("2021-08-26"))];
echo "<br>";
