convert unix timestamp php

问题:

I have a database that stores the time for me. I insert it from PHP using

date( 'Y-m-d H:i:s');

I then use this function to convert it to a unix timestamp in PHP

function convert_datetime($str)  { list($date, $time) = explode(' ', $str); list($year, $month, $day) = explode('-', $date); list($hour, $minute, $second) = explode(':', $time);  $timestamp = mktime($hour, $minute, $second, $month, $day, $year);  return $timestamp; }

What I now need to do is convert this timestamp to the date and time in this format: yyyymmddhhmmss (without any hyphens, dashes, colons, etc).

Has anyone any ideas?

回答1:

You can use the strtotime and date function:

echo date('Ymdhis', strtotime($date));

回答2:

Use date.

$date = date("YmdHis", $timestamp);

回答3:

here you go

print date("YmdHis",unixtimestamp);

回答4:

If you're using mysql, it has a DATE_FORMAT function. You can call it like

SELECT DATE_FORMAT(`datefield`, "%Y%m%d%H%i%s") AS `date_formatted` FROM table;

So you get an already formatted date from your database.

Use the right format :

date('YmdHis');
