Convert month number to month short name

Question

I have a variable with the following value

$month = 201002; 

the first 4 numbers represent the year, and the last 2 numbers represent the month. I need to get the last 2 numbers in the month string name eg. Feb

My code looks like this

<?php echo date('M',substr($month,4,6)); ?>

I can I go about to obtain the month name

Answer 1

Append "01" and strtotime will be able to parse the string :

echo date('M', strtotime($month . '01'));
