How to get utf-8 in json_encode php when convert from array to string?

Question

How to get utf-8 in json_encode php when convert from array to string ?

This is my code for test.php:

<meta content="text/html;charset=UTF-8" http-equiv="Content-Type">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<?PHP
session_start();
include("connect.php");
$word = mysqli_real_escape_string($db_mysqli,$_GET['word']);
$xx = array();
$xx[] = $word;
$xx[] = $word;
$xx_1 = json_encode($xx);
print_r($xx_1);
?>

When test load

example.com/test.php?word=神州

It's show

["\u795e\u5dde","\u795e\u5dde"]

I want to show like this

["神州","神州"]

$xx_1 = json_encode($xx, JSON_UNESCAPED_UNICODE);
print_r($xx_1);.

works for php5.4+

Actually ["\u795e\u5dde"] is same as ["神州"]. most of the time you json_encode the data before storing/transferring data around and after that you have to json_decode the value and process it, the json_docode will take care of the unicodification. But the above code should give you what you needed.

With this code it's not show anything $xx_1 = json_encode($xx, JSON_UNESCAPED_UNICODE); print_r($xx_1);.

i don't know why its like this in your case, but when i tried it my console >>>json_encode(['神州'], JSON_UNESCAPED_UNICODE); => "["神州"]" the proper output came

it shows nothing means the array itself might be empty

<meta content="text/html;charset=UTF-8" http-equiv="Content-Type"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8">  <?PHP session_start(); include("connect.php"); $word = mysqli_real_escape_string($db_mysqli,$_GET['word']); $xx = array(); $xx[] = $word; $xx[] = $word; //$xx_1 = json_encode($xx); $xx_1 = json_encode($xx, JSON_UNESCAPED_UNICODE); print_r($xx_1); ?>
