Solution to the problem that json_encode in php does not support GB2312 encoding

In the previous article, we introduced the problem of Chinese UNICODE transcoding in json_encode in php, so today we will continue to introduce to you the problem that json_encode in php does not support GB2312 encoding, in php Using json_encode() Built-in function(php > 5.2) can be used. The data in php can be transferred well with other languages ​​​​and used. The function of this function is to convert values ​​into json data storage format.

is as follows:

$arr = array('Name'=>'希亚', 'Age'=>20); 
$jsonencode = json_encode($arr); 
echo $jsonencode;

Running results:

{"Name":null,"Age":20}

The Chinese in the json_encode function is encoded as null. Google it. It is very simple. In order to communicate with the front-end Tightly integrated, Json only supports utf-8 encoding. I think it is the reason why the front-end Javascript is also utf-8. The solution is as follows:

$array = array (     
'title'=>iconv('gb2312','utf-8','这里是中文标题'),     
'body'=>'abcd...' );  
echo json_encode($array);

Running results:

{"title":"\u8fd9\u91cc\u662f\u4e2d\u6587\u6807\u9898","body":"abcd..."}

All Chinese characters in the array are missing or \u2353 etc. appear after json_encode.

The solution is to use the urlencode() function to process the following. Before json_encode, use urlencode() to process all the contents of all arrays, and then use json_encode() to convert them into jsonString, and finally use urldecode() to convert the encoded Chinese back.

A sample program is as follows:

/************************************************************** 
 * 
 *    使用特定function对数组中所有元素做处理 
 *    @param    string    &$array        要处理的字符串 
 *    @param    string    $function    要执行的函数 
 *    @return boolean    $apply_to_keys_also        是否也应用到key上 
 *    @access public 
 * 
 *************************************************************/ 
function arrayRecursive(&$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--; 
} 
 
/************************************************************** 
 * 
 *    将数组转换为JSON字符串（兼容中文） 
 *    @param    array    $array        要转换的数组 
 *    @return string        转换得到的json字符串 
 *    @access public 
 * 
 *************************************************************/ 
function JSON($array) { 
    arrayRecursive($array, 'urlencode', true); 
    $json = json_encode($array); 
    return urldecode($json); 
} 
 
$array = array('Name'=>'希亚', 'Age'=>20); 
 
echo JSON($array);
