孟加拉字体的 JSON 编码错误

Question

一切正常。但是当我尝试从 mysql 数据库中编码一些孟加拉语字体时，问题发生了。孟加拉语字体显示为“?????????????”。

** php文件**

<?php 
define('HOST','localhost');
define('USER','xxxxxxx');
define('PASS','xxxxxxxx');
define('DB','xxxxxxxxx');

$con = mysqli_connect(HOST,USER,PASS,DB);

$sql = "select * from bookinfo ORDER BY ID DESC";

$res = mysqli_query($con,$sql);

$result = array();

while($row = mysqli_fetch_array($res)){
array_push($result,
array('id'=>$row[0],
    'name'=>$row[1],
    'writter'=>$row[2],
    'url'=>$row[3]
     ));
}

echo json_encode(array("result"=>$result), JSON_UNESCAPED_UNICODE);

mysqli_close($con);

?>

Answer 1

首先设置内容类型，例如。 header('Content-Type: application/json; charset=utf-8')

然后在执行查询之前设置 utf-8 代码

像这样：

<?php
header('Content-Type: application/json; charset=utf-8');    
define('HOST','localhost');
define('USER','xxxxxxx');
define('PASS','xxxxxxxx');
define('DB','xxxxxxxxx');    
$con = mysqli_connect(HOST,USER,PASS,DB);    
mysqli_query($con,"SET character_set_results = 'utf8', character_set_client = 'utf8', character_set_connection = 'utf8', character_set_database = 'utf8', character_set_server = 'utf8'");

$sql = "select * from bookinfo ORDER BY ID DESC";

$res = mysqli_query($con,$sql);

$result = array();

while($row = mysqli_fetch_row($res)){
array_push($result,
array('id'=>$row[0],
'name'=>$row[1],
'writter'=>$row[2],
'url'=>$row[3]
));
}   
echo json_encode(array("result"=>$result), JSON_UNESCAPED_UNICODE);    
mysqli_close($con);    
?>

它会按照您的预期为您提供正确的字体。
