这篇文章主要介绍了PHP date函数常用时间处理方法,本文介绍获取今天、明天、昨天、一周后、一个月前、一个月后等时间的方法,需要的朋友可以参考下
代码如下:
echo "今天:".date("Y-m-d")."
";
echo "昨天:".date("Y-m-d",strtotime("-1 day")), "
";
echo "明天:".date("Y-m-d",strtotime("+1 day")). "
";
echo "一周后:".date("Y-m-d",strtotime("+1 week")). "
";
echo "一周零两天四小时两秒后:".date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")). "
";
echo "下个星期四:".date("Y-m-d",strtotime("next Thursday")). "
";
echo "上个周一:".date("Y-m-d",strtotime("last Monday"))."
";
echo "一个月前:".date("Y-m-d",strtotime("last month"))."
";
echo "一个月后:".date("Y-m-d",strtotime("+1 month"))."
";
echo "十年后:".date("Y-m-d",strtotime("+10 year"))."
";
strtotime()函数的作用是将日期时间描述解析为 Unix 时间戳
int strtotime ( string time [, int now] )
PHP星期几获取代码:
复制代码 代码如下:
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
获取中文星期可以这样
复制代码 代码如下:
$weekarray=array("日","一","二","三","四","五","六");
echo "星期".$weekarray[date("w")];
获取指定日期是:
[code]
$weekarray=array("日","一","二","三","四","五","六");
echo "星期".$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
