Converting between PHP & MySql DateTime

I work most of the time in PHP and here are two functions I found to be helpful most of the time when dealing with DateTime value type between PHP & MySQL
(It’s not written by me, but shared by a friend of mine) So here to share with you!

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

/* * Convert PHP DateTime to MySQL DateTime * e.g: 20.10.2009 11:15:30 => 2009-10-20 11:15:30 */ function php2mysql_datetime($php_datetime){ return date('Y-m-d H:i:s', strtotime($php_datetime)); }   /* * Convert MySQL DateTime to PHP DateTime * e.g: 2009-10-20 11:15:30 */ function mysql2php_datetime($mysql_datetime){ # getting the date $d = split(' ', $mysql_datetime); if($d && count($d)>1){ list($year, $month, $day) = split("-", $d[0]); list($hour, $minute, $second) = split(":", $d[1]); $d = date('d.m.Y H:i:s', mktime($hour, $minute, $second, $month, $day, $year));} else if($d & count($d)==1){ list($year, $month, $day) = split("-", $d[0]); $d = date('d.m.Y', mktime(0, 0, 0, $month, $day, $year)); } else { $d = NULL; } return $d; }
