json不支持中文写入的问题解决

写两个函数，使其支持中文：

function arrayRecursive(&$array, $function, $apply_to_keys_also = false)
{
foreach ($array as $key => $value) {
if (is_array($value)) {
arrayRecursive($array[$key], $function, $apply_to_keys_also);
} else {
$array[$key] = $function($value);
}

if ($apply_to_keys_also && is_string($key)) {
$new_key = $function($key);
if ($new_key != $key) {
$array[$new_key] = $array[$key];
unset($array[$key]);
}
}
}
}

function JSON($array) {
arrayRecursive($array, 'urlencode', true);
$json = json_encode($array);
return urldecode($json);
}

调用示例如下：

$guanggao_list=array(
