php获取时间是星期几

PHP星期几获取代码：

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")];

获取指定日期是：

$weekarray=array("日","一","二","三","四","五","六");
echo "星期".$weekarray[date("w",strtotime("2011-11-11"))];
