【技术解读】用php获取本周,上周,本月,上月,本季度日期的代码
PHP date函数参数详解
time()在PHP中是得到一个数字,这个数字表示从1970-01-01到现在共走了多少秒,很奇怪吧
不过这样方便计算,
要找出前一天的时间就是 time()-606024;
要找出前一年的时间就是 time()606024365
那么如何把这个数字换成日期格式呢,就要用到date函数了
$t=time();
echo date("Y-m-d H:i:s",$t);
第一个参数的格式分别表示:
a - "am" 或是 "pm"
A - "AM" 或是 "PM"
d - 几日，二位数字，若不足二位则前面补零; 如: "01" 至 "31"
D - 星期几，三个英文字母; 如: "Fri"
F - 月份，英文全名; 如: "January"
h - 12 小时制的小时; 如: "01" 至 "12"
H - 24 小时制的小时; 如: "00" 至 "23"
g - 12 小时制的小时，不足二位不补零; 如: "1" 至 12"
G - 24 小时制的小时，不足二位不补零; 如: "0" 至 "23"
i - 分钟; 如: "00" 至 "59"
j - 几日，二位数字，若不足二位不补零; 如: "1" 至 "31"
l - 星期几，英文全名; 如: "Friday"
m - 月份，二位数字，若不足二位则在前面补零; 如: "01" 至 "12"
n - 月份，二位数字，若不足二位则不补零; 如: "1" 至 "12"
M - 月份，三个英文字母; 如: "Jan"
s - 秒; 如: "00" 至 "59"
S - 字尾加英文序数，二个英文字母; 如: "th"，"nd"
t - 指定月份的天数; 如: "28" 至 "31"
U - 总秒数
w - 数字型的星期几，如: "0" (星期日) 至 "6" (星期六)
Y - 年，四位数字; 如: "1999"
y - 年，二位数字; 如: "99"
z - 一年中的第几天; 如: "0" 至 "365"
其它不在上列的字符则直接列出该字符
下面是实际使用方式：
<?php
echo date("Ymd",strtotime("now")), "\n";
echo date("Ymd",strtotime("-1 week Monday")), "\n";
echo date("Ymd",strtotime("-1 week Sunday")), "\n";
echo date("Ymd",strtotime("+0 week Monday")), "\n";
echo date("Ymd",strtotime("+0 week Sunday")), "\n";
echo "*********第几个月:";
echo date('n');
echo "*********本周周几:";
echo date("w");
echo "*********本月天数:";
echo date("t");
echo "*********";
echo '<br>上周起始时间:<br>';
echo date("Y-m-d H:i:s",mktime(0, 0 , 0,date("m"),date("d")-date("w")+1-7,date("Y"))),"\n";
echo date("Y-m-d H:i:s",mktime(23,59,59,date("m"),date("d")-date("w")+7-7,date("Y"))),"\n";
echo '<br>本周起始时间:<br>';
echo date("Y-m-d H:i:s",mktime(0, 0 , 0,date("m"),date("d")-date("w")+1,date("Y"))),"\n";
echo date("Y-m-d H:i:s",mktime(23,59,59,date("m"),date("d")-date("w")+7,date("Y"))),"\n";
//从第几周找出该周的开始日期和结束日期
$dayNumber = date('W') * 7;
$weekDayNumber = date("w", mktime(0, 0, 0, 1, $dayNumber, date("Y")));//当前周的第几天
$startNumber = $dayNumber - $weekDayNumber;
echo date("Y-m-d", mktime(0, 0, 0, 1, $startNumber + 1, date("Y")));//开始日期
echo date("Y-m-d", mktime(0, 0, 0, 1, $startNumber + 7, date("Y")));//结束日期
echo '<br>上月起始时间:<br>';
echo date("Y-m-d H:i:s",mktime(0, 0 , 0,date("m")-1,1,date("Y"))),"\n";
echo date("Y-m-d H:i:s",mktime(23,59,59,date("m") ,0,date("Y"))),"\n";
echo '<br>本月起始时间:<br>';
echo date("Y-m-d H:i:s",mktime(0, 0 , 0,date("m"),1,date("Y"))),"\n";
echo date("Y-m-d H:i:s",mktime(23,59,59,date("m"),date("t"),date("Y"))),"\n";
$season = ceil((date('n'))/3);//当月是第几季度
echo '<br>本季度起始时间:<br>';
echo date('Y-m-d H:i:s', mktime(0, 0, 0,$season*3-3+1,1,date('Y'))),"\n";
echo date('Y-m-d H:i:s', mktime(23,59,59,$season*3,date('t',mktime(0, 0 , 0,$season*3,1,date("Y"))),date('Y'))),"\n";
$season = ceil((date('n'))/3)-1;//上季度是第几季度
echo '<br>上季度起始时间:<br>';
echo date('Y-m-d H:i:s', mktime(0, 0, 0,$season*3-3+1,1,date('Y'))),"\n";
echo date('Y-m-d H:i:s', mktime(23,59,59,$season*3,date('t',mktime(0, 0 , 0,$season*3,1,date("Y"))),date('Y'))),"\n";
