PHP PDO - 使用UTF-8编码的Json

Question

I have this data to datatable cell: AlgoVital Plus čćš so some characters is utf-8

Here's my database schema

After that I make json file with php and send it to fronted:

//header
header('Content-Type: text/html; charset=utf-8');
...
...
//at the end of php file:
 $jsonTable = json_encode($table);
    //echo $jsonTable;
    } catch(PDOException $e) {
        echo 'ERROR: ' . $e->getMessage();
    }
    echo $jsonTable;

and HTML head is OK too:

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

but I cant show data with utf-8 characters... WHy?

JSON is not format with utf-8 characers... etc. where I have some characters like čćšž then I just get NULL at JSON file, when I use json encode

How I can solve this?

Answer 1

Try with this:

$table = utf8_encode($table);
$jsonTable = json_encode($table);
