PHP中获取星期几实例程序

1 date(“l”)；

2 //data就可以获取英文的星期比如Sunday

3 date(“w”)；

4 //这个可以获取数字星期比如123，注意0是星期日

1 $weekarray=array(“日”，“一”，“二”，“三”，“四”，“五”，“六”)；

2 //先定义一个数组

3 echo “星期”.$weekarray[date(“w”)]；

1 $weekarray=array(“日”，“一”，“二”，“三”，“四”，“五”，“六”)；

2 echo “星期”.$weekarray[date(“w”，“2011-11-11”)]；

<?php
//php获取今天是星期几
function getWeek($unixTime=''){
 $unixTime=is_numeric($unixTime)?$unixTime:time();
 $weekarray=array('日','一','二','三','四','五','六');
 return '星期'.$weekarray[date('w',$unixTime)];
}
echo getWeek();

<?php
