print_R($result);

Answer 1

Change
$result = json_decode($response);
To
$result = json_decode($response, true);
Then
echo '<pre>';
print_r($result);
Response:-
Array
(
[statusCode] => 401
[error] => Unauthorized
[message] => Invalid username or password
[responseType] => INVALID_USER_PASS
)

Answer 2

change your post array
$post = array('email'=> "example#xyz.com",'password'=> "testing");
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://35.154.149.228:8000/api/admin/login');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$response = curl_exec($ch);
$result = json_decode($response);
print_r($result);

Answer 3

Try displaying errors just in case the errors/warnings are suppressed.
use these at the top of the file, just after the php tags
ini_set("display_errors", "On");
error_reporting(E_ALL);
Also try to print the raw response before json_decoding it, this is because if the response you are getting is not valid json nothing would be printed out after decoding it.
Use this
print_r("The response is: " . $response);
In summarry your code should look like
ini_set("display_errors", "On");
error_reporting(E_ALL);
$post = ['email'=> "example#xyz.com",'password'=> "testing"];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://35.154.149.228:8000/api/admin/login');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
$response = curl_exec($ch);
//Printing the original response before trying to decode it
//$result = json_decode($response);
print_r("The response from the server before decoding is: " . $response);
Let us know what the exact response you get from this is
