How do I get Facebook page username or facebook page ID from url

问题

I've made a website where users can submit their Facebook page and I orginally coded it assuming that they would of set up a vanity URL for their page. E.g.

http://www.facebook.com/myfacebookpage

But I forgot that some pages can have urls such as

http://www.facebook.com/pages/myfacebookpage/54878424154545487

My question is how do I use PHP to grab the part of the url in bold?

Thanks!

like this:

$url='http://www.facebook.com/pages/myfacebookpage/54878424154545487'; // the input
$pieces = explode('/', $url); // divides the string in pieces where '/' is found
$key=end($pieces); //takes the last piece

You can just recode your application to use https://graph.facebook.com/?ids=

Which will take both

• http://www.facebook.com/myfacebookpage and
• http://www.facebook.com/pages/myfacebookpage/54878424154545487

Examples

• https://graph.facebook.com/?ids=https://www.facebook.com/boo
• https://graph.facebook.com/?ids=https://www.facebook.com/pages/phwd/113702895386410
