how to re-format datetime string in php?

Question

I receive a datetime from a plugin. I put it into a variable:

$datetime = \"20130409163705\"; 

That actually translates to yyyymm

Answer 1

For PHP 5 >= 5.3.0 http://www.php.net/manual/en/datetime.createfromformat.php

$datetime = "20130409163705"; 
$d = DateTime::createFromFormat("YmdHis", $datetime);
echo $d->format("d/m/Y H:i:s"); // or any you want

Result:

09/04/2013 16:37:05
