JSON array accent display - javascript

I'm trying to display a json array with contents from my database but when their is accents in the database the json array doesn't want to be displayed, their is my code:
<?php
include 'connect.php';
header('Content-Type: text/plain; charset=UTF-8') ;
$serial = 1;
$statment = mysqli_prepare($conn, "SELECT * FROM lesson WHERE serial = ?");
mysqli_stmt_bind_param($statment, "i", $serial);
mysqli_stmt_execute($statment);
mysqli_stmt_store_result($statment);
mysqli_stmt_bind_result($statment, $serial, $by, $type, $description, $lesson, $nb_q);
$response = array();
$response["success"] = false;
while(mysqli_stmt_fetch($statment)){
$response["success"] = true;
$response["serial"] = $serial;
$response["by"] = $by;
$response["type"] = $type;
$response["lesson"] = $lesson;
$response["description"] = $description;
$response["nb_q"] = $nb_q;
for ($i = 1; $i <= $nb_q; $i++) {
$statment2 = mysqli_prepare($conn, "SELECT * FROM question WHERE 4_l_id = ? AND q_num = ?");
mysqli_stmt_bind_param($statment2, "ii", $serial, $i);
mysqli_stmt_execute($statment2);
mysqli_stmt_store_result($statment2);
mysqli_stmt_bind_result($statment2, $question, $nb_answer, $type, $correct_1, $for_l_id, $id, $q_num);
while(mysqli_stmt_fetch($statment2)){
$response["q".$i] = $question;
}
}
}
echo json_encode($response, JSON_UNESCAPED_UNICODE);
?>
Thank you for your answers

I found a good code but thank you for your help,
<?php

mysqli_stmt_bind_result($statment, $serial, $by, $type, $description, $lesson, $nb_q);
$response = array();
$response["success"] = false;
function utf8_encode_all(&$value)
{
if (is_string($value)) return utf8_encode($value);
if (!is_array($value)) return $value;
$ret = array();
foreach($dat as $i=>$d) $ret[$i] = utf8_encode_all($d);
return $ret;
}

Having json inside autocomplete

How come autocomplete doesnt work when I got json data that has items in it? I can se that it is becoming a list, but it is not filling with names.
Example of my json data: http://nettport.com/no/stram/search.php?term=e

var energy = ui.item.energy;
var proteins = ui.item.proteins;
var carbohydrates = ui.item.carbohydrates;
var fat = ui.item.fat;
$("#inp_energy_a_0").val((energy*val)/100);
$("#inp_proteins_a_0").val((proteins*val)/100);
$("#inp_carbs_a_0").val((carbohydrates*val)/100);

How to show message in view & replace a div using ajax in codeigniter?

I am stuck with ajax... I have a cart and it has gift vouchers,

ii) If voucher if valid and is set in db,then change the cart total using gift amount.
So I have set the message , but i dont know how to dislay it.And Using gift i have stored the new cart total ie gift_cart_total.In db, i have fields for cart_total,voucher , gift_cart_total.How can i remove my original cart div and show new div using gift_cart_total.

mysqli query not working in foreach php

My problem now when I click on the picture on my page, for the first time it will display. But for the second time it will display fail. This process will start by sending the data to ajax, then ajax(prosess.js) will send it to the php page(process1.php).
When I remove the code in blockquote ($query = "SELECT ...") it will run, but if not, it will display fail.

your query is wrong:try this
$query = "SELECT prodName FROM product WHERE prodName = '".$item."'";
According to your pictures, your problem is that your database connection isn't correct. When you execute the first request it won't do any database interaction (because off the blocknotes). The second request you will send table data, which will perform a query. So the first request will succeed, while the second request will give you an error on your mysqli ($conn) object.
if($table == "") {
//Database interaction
$query = "SELECT * FROM product WHERE serialNum = '$serial'";
$result = mysqli_query($conn, $query);
$row = mysqli_fetch_assoc($result);
}
else{
//No database interaction because of the blocknotes
$DOM = new DOMDocument;
$DOM->loadHTML($table);
$items = $DOM->getElementsByTagName('tr');
$check = 0;
$check_one = 0;
$y=0;
function tdrows($elements,$check,$serial,$prodName,$y) {
$quantity="";
$item = "";
$price = "";
$delete = "";
$x = 0;
foreach($elements as $element) {
if($x == 0)
$delete = $element->nodeValue;
else if($x == 1)
$item = $element->nodeValue;
else if($x == 2)
$quantity = $element->nodeValue;
else if($x == 3)
$price = $element->nodeValue;
$x++;
}
**$query = 'SELECT prodName FROM product WHERE prodName = "$item"';
$search = mysqli_query($conn, $query) or die(mysqli_error());
$row = mysqli_fetch_assoc($search);
$s = $row['prodName'];**
if($prodName == $s) {
$quantity++;
$check = 1;
}
else {
$check = 0;
}
return $check;
}
foreach ($items as $node) {
$check = tdrows($node->childNodes,$check,$serial,$prodName,$y);
$y++;
}
}
Check your the username, password and database name. I'm pretty sure you used something wrong here. As mentioned in your connection.php file you don't use a password. Are you sure the user root doens't have a password? Can you access the database with a MySQL administration tool like phpMyAdmin?

This wont delete from database, what am I doing wrong to delete it from database?
