This is the time stamp conversion, the date function has a lot of conversion, the first parameter is to represent the format you need, if sometimes you need only time stamp to provide date, and then a few minutes of the data you decide, you can use this way to convert the time stamp into the form of a month and a day, Then stitching on the time data, to the space then a few points: a few seconds.

$ysubstr($remind_date,0,4);$msubstr($remind_date,5,2);$dsubstr($remind_date,8,2);

If you receive the time data for the 2015-02-05, you can get the time you want by substr this string truncation method, you can get the number of month and day corresponding

$end_time = strtotime($data[‘end_time‘]);
