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","2011-11-11")];

因为date函数非常强大,他完全可以胜任一切这样的工作我附个手册里的表吧 方便随时查阅
