php - MySQL to JSON Encode Error / No Results -

i know type of question has been asked couple of times problem little bit different , can't figure out of fix this. i've checked other similar questions couldn't find solution since seems correct.

i have database table named kalkanlimekanlar , has 3 tables inside it. right now, want encode contents of mekanlar table. has 5 columns , 22 rows inside it.

when run following php code, see no result. i'd grateful if can me this.

i don't know if helps server on digitalocean.

thank help!

php code:

$sql = "select * mekanlar";  $result = mysqli_query($connection, $sql) or die("error in selecting " . mysqli_error($connection));  $emparray[] = array();  while($row =mysqli_fetch_assoc($result)) {     $emparray[] = $row; }  echo json_encode($emparray);  mysqli_close($connection); 

thank help!

after doing @rhinodevel's suggestion, this

while($row =mysqli_fetch_assoc($result)) {      array_push($emparray,$row); } 

edit : following comments rhino,

    $array[] = array ();     ($i = 0 ; $i < 5 ; $i++) {         $array[] = $i;     }     $logger->info("op : " . json_encode($array));     $array = array ();     ($i = 0 ; $i < 5 ; $i++) {         $array[] = $i;     }     $logger->info("rd : " . json_encode($array));      $array = array ();     ($i = 0 ; $i < 5 ; $i++) {         array_push($array , $i);     }     $logger->info("yl : " . json_encode($array)); 

yields :
