How to use function from a functions.php file in angular

Question

I want to retrieve users info by a function in PHP in my angular.

angular code:

$scope.users = $http({
  method: 'GET',
   url: 'functions.php/getUsers()'
  }).then(function(response){
   $scope.users = response.data;
  },function(reason){
   $scope.error = reason.data;
  });
}

where getUsers() is the function which is returning json data to the angular.

is there any other way to use functions in angular from a PHP files?

remember the functions can not be equal to our public variable, in this sample you have $scope.users as function and also you have that again equal to response.data (actually you miss the function)

you can't read from files, you have to use api URL which return json to you

$scope.users = $http({
  method: 'GET',
   url: 'functions.php/getUsers()'
  }).then(function(response){
   $scope.users = response.data;
  },function(reason){
   $scope.error = reason.data;
  });
}

change to

$scope.getUsers = function(){
  //for example api url for your users is "http://localhost:8080/users"
  var api = "you api url";
  $http({method: 'GET', url: api}).then(function(response){
   $scope.users = response.data;
  },function(reason){
   $scope.error = reason.data;
  });
 }    
}
//request data
$scope.getUsers();

OR use it directly without function

//for example api url for your users is "http://localhost:8080/users"
var api = "you api url";
$http({method: 'GET', url: api}).then(function(response){
  $scope.users = response.data;
},function(reason){
  $scope.error = reason.data;
});
}

no where! the PHP files not related to your js files because you currently want to get data from your api so use it directly from your js.

ok so update your question with functions.php -> getUsers() function and let us see what you did in that.

You can not call a PHP function in a JavaScript file in this way. You can do it by following these steps:

1) create get-users.php file

<?php
    require 'functions.php';  

    echo getUsers();
?>

2) make the http request to the created file

$scope.users = $http({
    method: 'GET',
    url: 'your-website-url/get-users.php'
 }).then(function(response){
    $scope.users = response.data;
 },function(reason){
   $scope.error = reason.data;
 });
}

Update

if you have a lot of functions and don't want to create a file for every function. then you can do it like this:

1) create all-functions.php file

<?php

  require 'functions.php';

  if (function_exists($_GET['func'])) {
    echo call_user_func($_GET['func']);
  } else {
     echo "Error: function does not exist";
  }

  ?>

2) Update your angular code

 $scope.users = $http({
    method: 'GET',
    url: 'your-website-url/all-functions.php',
    data: {
        func: 'getusers' 
     }
 }).then(function(response){
    $scope.users = response.data;
 },function(reason){
   $scope.error = reason.data;
 });
}
