passing url parameters in angular

I'm trying to pass some url parameter between view to get the detail of a particular user but i'm finding it hard to do

.controller('profile_detail_ctrl',['$scope','$http','$state',function($scope,$http,$state){
$http.get('http://localhost/myapp/app_ion/templates/profile/profile.php?profile_id='+$scope.profile_detail).success(function(data){
       $scope.profile_detail=data;
       $scope.profile_id=$state.params.profile_id;

   });
