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 inphp, 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-endJavascriptis 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);
