php string formatting into time

In normal times we often need to format the time of a string before using it

Php can use the following method:

$temp_date = '2011-01-09 19:25:43';
date('Y-m-d',strtotime($temp_date)); //这个的输出是 2011-01-09

The function of strtotime is-- Parse the date and time description of any English text into a UNIX timestamp

The following is the official description:

int strtotime ( string time [, int now])

This function is expected to accept a string containing an English date format and try to parse it into a UNIX timestamp. If the format of time is absolute time, the now parameter has no effect.

If the format of time is a relative time, the relative time is provided by now, or the current time is used if the now parameter is not provided. Returns -1 on failure.

The programs must be relatively robust, then we can judge whether they can be converted.

It should also be noted that this has a time interval: Friday, December 13, 1901 at 20:45 :54 Until Tuesday, January 19, 2038 03:14:07
