我有一个多维数组。我想将该数组转换为JSON。我正在使用[global::System.Data.Linq.Mapping.TableAttribute(Name= "LeumiApp.dbo.CategoryVariants")]
，但无法正常工作。
这是我正在使用的代码。
json_encode**下面的函数已写在helper_functions.php中**
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
header('Content-Type: application/json');
include '../panel/config/conn.php';
include '../panel/config/helper_functions.php';
$postions = array(1 => "Goalkeeper", 2 => "Defender", 3 => "Midfielder", 4 => "Forward");
$result = array();
$tmp = get_football_assets($conn);
foreach ($tmp as $key => $value) {
$pair = strtolower($value['pair']);
$value['pair'] = $pair;
$value['position'] = $postions[$value['position_id']];
unset($value['position_id']);
$result[$pair] = $value;
}
echo json_encode($result);
如果我执行function get_football_assets($con){
$data = array();
$sql = "SELECT nationality, birthdate, birthcountry, birthplace, height, weight, players.position_id as position_id, players.image_path as image_path, teams.name as club, countries.name as country, feed.pair as pair, feed.fullname as name, feed.price as price from players JOIN feed ON feed.player_id = players.api_id JOIN teams ON teams.api_id = players.team_id JOIN countries ON countries.api_id = players.country_id";
mysqli_set_charset($con, 'utf8');
$result = mysqli_query($con, $sql);
while($rows = mysqli_fetch_assoc($result)){
$data[] = $rows;
}
return $data;
}
，则它显示以下结果，但由于输出具有1500多个记录，所以我仅显示3条记录：-
print_r($result) [sergeaurier95094] => Array
(
[nationality] => C�te d'Ivoire
[birthdate] => 24/12/1992
[birthcountry] => C�te d'Ivoire
[birthplace] => Ouragahio
[height] => 176 cm
[weight] => 76 kg
[image_path] => https://cdn.sportmonks.com/images/soccer/players/22/95094.png
[club] => Tottenham Hotspur
[country] => C�te d'Ivoire
[pair] => sergeaurier95094
[name] => Serge Aurier
[price] => 10.00
[position] => Defender
),
[davinsons�nchezmina26294] => Array
(
[nationality] => Colombia
[birthdate] => 12/06/1996
[birthcountry] => Colombia
[birthplace] => Caloto
[height] => 187 cm
[weight] => 81 kg
[image_path] => https://cdn.sportmonks.com/images/soccer/players/22/26294.png
[club] => Tottenham Hotspur
[country] => Colombia
[pair] => davinsons�nchezmina26294
[name] => Davinson S�nchez Mina
[price] => 10.00
[position] => Defender
),
[lucasrodriguesmouradasilva95998] => Array
(
[nationality] => Brazil
[birthdate] => 13/08/1992
[birthcountry] => Brazil
[birthplace] => S�o Paulo
[height] => 172 cm
[weight] => 72 kg
[image_path] => https://cdn.sportmonks.com/images/soccer/players/30/95998.png
[club] => Tottenham Hotspur
[country] => Brazil
[pair] => lucasrodriguesmouradasilva95998
[name] => Lucas Rodrigues Moura da Silva
[price] => 10.00
[position] => Midfielder
)
返回的 UTF-8格式错误的字符，可能编码错误。
修改
我已按照建议删除了array_map并使用了echo json_last_error_msg();，但是它无法转换 alissonrams.sbecker129820，davinsons.nchezmina26294，nabydecoke.ta32640等字符。
mysqli_set_charset($con, 'utf8');实际上，问题出在echo bin2hex($pair); gives me the following output :-

上。因此，对我来说效果很好的更新代码如下：-
