Question

Im just using the graph.facebook.com code to display photos from an album but i want the user to be able to paste the URL from their album and then using a php regular expression or javascript i would like to remove everything but the album id so i can display the photos.

If a user pastes this to their users MYSQL table:

https://www.facebook.com/media/set/?set=a.10152107362775359.906732.14226545341&type=3

What would be the best way to retrieve only the numbers after a. and before where the next . starts.

basically i need this: 10152107362775359

I know i can get everything that set=

$notclean = 'a.10152107362775359.906732.14226545341';

but now how do i make

$notclean = '10152107362775359';

Thanks in advance 🙂

Use the explode() function:

$str = 'a.10152107362775359.906732.14226545341';
$arr = explode(".",$str);
$notclean = $arr[1];
