regex to find year/month substring

Can someone help me with a regular expression to get the year and month from a text string?

Here is an example text string:

http://www.domain.com/files/images/2012/02/filename.jpg

I'd like the regex to return 2012/02.

Depending on your situation and how much your strings vary - you might be able to dodge a bullet by simply using PHP's handy explode() function.

A simple demonstration - Dim the lights please...

$str = 'http://www.domain.com/files/images/2012/02/filename.jpg';
print_r( explode("/",$str) );

Returns :

Array
(
    [0] => http:
    [1] =>
    [2] => www.domain.com
    [3] => files
    [4] => images
    [5] => 2012      // Jack
    [6] => 02        // Pot!
    [7] => filename.jpg
)

The explode() function (docs here), splits a string according to a "delimiter" that you provide it. In this example I have use the / (slash) character.

So you see - you can just grab the values at 5th and 6th index to get the date values.

This regex pattern would match what you need:

(?<=\/)\d{4}\/\d{2}(?=\/)
