Users.php

    $phone = $_GET['phone'];
    $fullname = $_GET['fullname'];

$dbcontroller = new DBController();

$this->users = $dbcontroller->executeupdateuserQuery($query);

}

DBController.php

function executeupdateuserQuery($query) {

mysqli_set_charset($conn,'utf8');    
$result = mysqli_query($this->conn,$query);

if ($result)
{
    return "user_updated";
}else{
    return "failed_updated";
}       

}

Answer 1

when you run mysql connect , you must set

   mysql_query("SET NAMES 'utf8'");

and for mysqli

$mysqli->set_charset("utf8")

full example:

$connect = mysql_connect($this->hosttype,$this->dbusername,$this->dbpassword)or die('error');
mysql_query("SET NAMES 'utf8'");
$select = mysql_select_db($this->dbname,$connect)or die('error');

Answer 2

you can change the 'Collation' of column to 'utf8mb4_persian_ci' or 'utf8_persian_ci'.

it works.

Answer 3

The data that you insert should have utf8 encoding. You can encode the data using utf8_encode function. For example:

$fullname = utf8_encode($_GET['fullname']);
