Use strtotimefunction of PHP.
使用strtotimePHP的功能。
The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.
该函数期望得到一个包含英文日期格式的字符串，并将尝试将该格式解析为 Unix 时间戳（自 1970 年 1 月 1 日 00:00:00 UTC 以来的秒数），相对于 now 给出的时间戳，或如果现在没有提供当前时间。
echo strtotime('2012-03-27 18:47:00'); //--> which results to 1332866820
And to make it back again, just use the datefunction of PHP:
而要让它重新回来，只需使用datePHP的功能：
$long = strtotime('2012-03-27 18:47:00'); //--> which results to 1332866820
echo date('Y-m-d H:i:s', $long);

check this
检查这个
<?php
$timestamp = strtotime('1st January 2004'); //1072915200
// this prints the year in a two digit format
// however, as this would start with a "0", it
// only prints "4"
echo idate('y', $timestamp);
?>
