我有问题从数据库获取数据。波斯语单词出现像???????这样的问号。我怎么能避免这个？

这是我的代码：

header('Content-Type: text/html; charset=utf-8');
$conn = mysqli_connect("localhost", "somevalue", "somevalue", "somevalue");
$output = array();
$query  = "SELECT * FROM af_home ORDER BY home_id DESC LIMIT 50";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_array($result)) {
        $output[] = $row;
    }
    echo json_encode($output);
}

Answer 1

确保af_home列charset是数据库中的UTF-8

Answer 2

您可以转换数据库UTF-8：

ALTER DATABASE your_database CHARACTER SET utf8;
-- for each table:
ALTER TABLE some_table CONVERT TO CHARACTER SET utf8;

并确保该表是UTF8：

SET CHARACTER SET, SET NAMES, SET COLLATION_CONNECTION
