Hi guy's is it possible using php simply grab data from a php page?

The php page looks like this...

Code:
{
         "id": "1486966978"
      },
      {
         "id": "1497131620"
      },
      {
         "installed": true,
         "id": "1509660136"
      },
      {
         "installed": true,
         "id": "1529210112"
      },
      {
         "id": "1569558425"
      },
      {

what i want to do is make my php page check that page and only grab the ID's where it says installed:true and then echo them...

(only want it to grab the numbers, if the page displays no installed:true, then it will display a message, saying no friends installed...


Is this possible?

Thanks
Jamie
