Solution for GBK/GB2312 page in PHP to lose Chinese using json_decode()_PHP Tutorial

In php, the json_decode() function can convert arrays to json format data. However, the json_decode() function only supports UTF-8 and ASCII encoding. If it is gkb, there will be problems. Let's take a look at the problem analysis. with solutions.

It seems that when using json_decode() to serialize an array/object into a JSON string, it basically only supports UTF-8/ASCII encoding. Some of our sites use GBK/GB2312 encoding. At this time, problems may occur when using json_encode/json_decode directly.

Results

The code is as follows

代码如下	复制代码
$json = '{"a":"中国人人"}'; var_dump(json_decode($json)); ?> 结果 {"text":null,"status":1}

Copy code

代码如下

复制代码

/*     字符串GBK转码为UTF-8，数字转换为数字。 */ function ct2($s){     if(is_numeric($s)) {         return intval($s);     } else {         return iconv("GBK","UTF-8",$s);     } } /*     批量处理gbk->utf-8 */ function icon_to_utf8($s) {   if(is_array($s)) {     foreach($s as $key => $val) {       $s[$key] = icon_to_utf8($val);     }   } else {       $s = ct2($s);   }   return $s; } echo json_encode(icon_to_utf8("厦门"));

$json = '{"a":"中国人人"}';
var_dump(json_decode($json));
?>

{"text":null,"status":1}

For example, when converting characters containing Chinese characters into null (null), but sometimes we have to use gb encoding and use json_decode() for conversion? What to do? Last night I wrote a small background for adding music without using a database. That is, use php to add music and then generate an xml menu. If you don't use a database, you have to use a way to save the data. The data saved as text can be used directly. I think it is to use json_decode() to convert the array into json format. When used, it can be taken out and used to json_encode to convert it back to the array (maybe js has been replaced by json recently. Affected, it seems that there are better ways to serialize arrays, such as using: serialize() and unserialize()), haha, let’s get back to the topic. Since json_decode() cannot convert Chinese in gb encoding, we can first convert Chinese into English encoding. Then you can use this urlencode() to convert the encoding, and then do json_decode() conversion. When using it, just use urldecode() to convert it to Chinese

The code is as follows
