Why is the variable not updated immediately after the http request?

Question

Angular

Hello. I'm new to angular so I'm asking for help explaining some of the nuances.
Question: why are the variables not updated immediately after the request?
So we have a controller, a factory and a file handler
Factory

app.factory('ld',function($http)
{
  text="11111";
  $http.post('php5.php').success(function(d){text=d;});
  return {al:function(){console.log(text)}}
});

Controller

app.controller('cont',function($http,ld)
{
  ld.al();
  setTimeout(function(){ld.al();},1000);
});

file handler

header('Content-Type: application/json');
$text="22222";
echo json_encode($text);

And here is the result in the console:

11111
22222

Is it possible to make variables in angular update immediately?

Answer 1

God, format the code properly. And give adequate names to controllers and services...

app.controller('cont', ['$http', '$timeout', 'ld', function($http, $timeout, ld) {
  ld.al();
  $timeout(function(){ld.al();},1000);
}]);
