php strtotime 将日间日期转换成时间时间戳
将日间日期转换成时间时间戳
strtotime(time,now)参数 描述
time 规定要解析的时间字符串。
now 用来计算返回值的时间戳。如果省略该参数,则使用当前时间。
<?php echo strtotime("now") , " "; echo strtotime("10 September 2000") , " "; echo strtotime("+1 day") , " "; echo strtotime("+1 week") , " "; echo strtotime("+1 week 2 days 4 hours 2 seconds") , " "; echo strtotime("next Thursday") , " "; echo strtotime("last Monday") , " ";
<?php $str = 'Not Good'; // previous to PHP 5.1.0 you would compare with -1, instead of false if (($timestamp = strtotime($str)) === false) { echo "The string ($str) is bogus"; } else { echo "$str == " . date('l dS o F Y h:i:s A', $timestamp); } /* 再看strtotime实例 */ echo strtotime('2010-2-14'),"<br />"; echo date('Y-m-d',strtotime('2010-2-14'));
//输出值
1266076800
2010-02-14
//你应该在strtotime(),你决定什么不能做。例如
<?php // on 2/8/2010 date('m/d/y', strtotime('first day')); // 02/01/10 date('m/d/y', strtotime('last day')); // 02/28/10 date('m/d/y', strtotime('last day next month')); // 03/31/10 date('m/d/y', strtotime('last day last month')); // 01/31/10 date('m/d/y', strtotime('2009-12 last day')); // 12/31/09 - this doesn't work if you reverse the order of the year and month date('m/d/y', strtotime('2009-03 last day')); // 03/31/09 date('m/d/y', strtotime('2009-03')); // 03/01/09 date('m/d/y', strtotime('last day of march 2009')); // 03/31/09 date('m/d/y', strtotime('last day of march')); // 03/31/10
