Question

我正在尝试使用json_encode对对象数组进行编码，但如果它遇到像Ñ这样的特殊字符，它会为该字段提供一个空值。我能够使用utf8_encode将2个字符串编码为uft8 主要问题是我无法使用utf8_encode对数组进行编码。你能帮我解决这个问题吗？

这是我的剧本：

Mysql查询

$consulta = "SELECT id AS nrocliente, empresa, nombre, tipodoc, doc, email, tel, cel, nombrealt, calle, numero, piso, depto, localidad, prov, codpostal FROM envio_clientes";
$result = mysqli_query($db, $consulta);

创建对象数组

//Se crea un array con todos los resultados
$cities = array();
while($row = mysqli_fetch_array($result,MYSQLI_ASSOC))
{
  $cities[] = array ( 'nrocliente' => $row['nrocliente'], 'empresa' => $row['empresa'], 'nombre' => $row['nombre'], 'tipodoc' => $row['tipodoc'], 'doc' => $row['doc'], 'email' => $row['email'], 'tel' => $row['tel'], 'cel' => $row['cel'], 'nombrealt' => $row['nombrealt'], 'calle' => $row['calle'], 'numero' => $row['numero'], 'piso' => $row['piso'], 'depto' => $row['depto'], 'localidad' => $row['localidad'], 'prov' => $row['prov'], 'codpostal' => $row['codpostal'] );
}

获取jQuery自动填充术语

// Cleaning up the term
$term = trim(strip_tags($_GET['term']));
// Rudimentary search
$matches = array();

创建一个稍后将由json_encode处理的新数组

foreach($cities as $city){
    if(stripos($city['nombre'], $term) !== false){
        // Add the necessary "value" and "label" fields and append to result set
         $city['value'] = utf8_encode($city['nombre']);
        //$city['label'] = "{$city['nombre']} {$city['localidad']}, {$city['nrocliente']}";
        $city['label'] = utf8_encode("{".$city['nombre']."} {".$city['localidad'] ."} {". $city['nrocliente']. "}");
        $matches[] = $city;
    }
}

请注意：在上面的代码中，$city['label']和$city['value']使用utf8_encode处理得很好。

json_encode流程

// Truncate, encode and return the results
$matches = array_slice($matches, 0, 5);
print json_encode($matches);
?>

这就是我的回应：

{"nrocliente":"2","empresa":"Medicas SRL","nombre":null,"tipodoc":"DNI","doc":"000000000","email":"","tel":"2223332222","cel":"","nombrealt":"","calle":"Av. Frey","numero":"222","piso":"","depto":"","localidad":"Capital","prov":"Santa Fe","codpostal":"3000","value":"Ivan \u00d1ibazeta","label":"{Ivan \u00d1ibazeta} {Capital} {2}"}]

请注意：字段nombre为空，但value和label显示相当于Ñ字符。

我应该怎样做才能将utf8_encode应用于$cities数组或$matches数组？
