如何在php中将yyyymm转换为mmyyyy

Question

I have this date (year and month) 201511 and I need to show in this format: 112015 (month and year).

I've tried this: date('m/Y', strtotime($date)), but does not work.

Answer 1

You have to read in the format you have and do that properly. date('m/Y') is not the format you feed into that function.

Read http://php.net/manual/datetime.createfromformat.php

or http://php.net/manual/function.date.php if you really have to use date().

m and n | Numeric representation of a month, with or without leading zeros | 01 through 12 or 1 through 12

Y | A full numeric representation of a year, 4 digits | Examples: 1999 or 2003

$dateStringOldFormat = '201511';
$dateStringNewFormat = DateTime::createFromFormat('Ym', $dateStringOldFormat)->format('mY');
