PHP JSON Chinese encoding for null solution _php Tips

Today, using the Json_encode function, we find that Chinese has become null.

Reason analysis: Use the Json_encode function should use the UTF-8 encoding, my page is GBK.

Workaround: Use the Iconv (' gbk ', ' UTF8 ') function before the Json_encode function. Function

function Gbk2utf8 ($data)
{
 if (Is_array ($data))
  {return
    array_map (' Gbk2utf8 ', $data);
  }
 Return Iconv (' GBK ', ' utf-8 ', $data);
}

Here's another way to find out.

PHP from the database to get the field is Chinese, want to use Json_encode () back to the foreground, but Json_encode encoded in Chinese is null.

Use the Json_encode () built-in function (Php > 5.2) in PHP to use the data in PHP to communicate well with other languages and use it.

The function of this function is to convert a numeric value into a JSON data storage format.

<?php
$arr = array
    (
     ' Name ' => ' Shia ',
     ' age ' =>20
    );

$jsonencode = Json_encode ($arr);
echo $jsonencode;
? >

The results of the program operation are as follows:
{' Name ': null, ' Age ': 20}
Json_encode function in Chinese is encoded into null, Google a bit, very simple, in order to close with the front-end, Json only support utf-8 encoding, I think the front-end Javascript is also the reason for Utf-8.

<?php
$array = array
	('
	 	title ' =>iconv (' gb2312 ', ' utf-8 ', ' Here is the Chinese title '),
		' body ' => ' abcd ... '
	);

echo Json_encode ($array);
? >

The results of this program are:
{"title": "\u8fd9\u91cc\u662f\u4e2d\u6587\u6807\u9898", "Body": "ABCD ..."}
All Chinese in the array are missing or appear \u2353 after Json_encode.
The solution is to use the UrlEncode () function to process the following, Json_encode all the contents of the array in UrlEncode (), and then convert the Json_encode () to the JSON string, and then the UrlDecode () Turn the encoded Chinese back in.

<?php/************************************************************** * * Use a specific function to handle all elements in the array * @param string & 
 amp; $array the string to be processed * @param string $function The function to be executed * @return Boolean $apply _to_keys_also is also applied to the key * @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, $app
    LY_TO_KEYS_ALSO);
    else {$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--; }
 
/**************************************************** Convert an array to a JSON string (compatible with Chinese) * @param array $array arrays to convert * @return string converted JSON String * @access public * /function JSON ($array) {arrayrecursive ($array, '
	UrlEncode ', true);
	$json = Json_encode ($array);
Return UrlDecode ($json);


$array = Array (' Name ' => ' Shia ', ' age ' =>20); echo JSON ($array);?>

The

was successful this time, and the results were as follows:
{"Name": "Shia", "Age": "}
