php json 中文乱码

方法一：

[php]
view plaincopyprint?

<?php
$code = json_encode($str);
$code = preg_replace("#\\\u([0-9a-f]+)#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", $code);
?>

方法二：

[php]
view plaincopyprint?

<?php
// 将数组转换成Json格式，中文需要进行URL编码处理
function Array2Json($array) {
arrayRecursive($array, 'urlencode', true);
$json = json_encode($array);
$json = urldecode($json);
// ext需要不带引号的bool类型
$json = str_replace("\"false\"","false",$json);
$json = str_replace("\"true\"","true",$json);
return $json;
}
function arrayRecursive(&$array, $function, $apply_to_keys_also = false)
{
static $recursive_counter = 0;
if (++$recursive_counter > 1000) {
die('possible deep recursion attack');
}
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]);
}
}
}
$recursive_counter--;
}
?>
