PHP solves JSON Chinese display problem
PHP如何解决JSON中文显示问题？本文主要介绍了PHP JSON格式的中文显示问题解决方法，本文总结了3种解决中文显示\u开头字符问题的方法。希望对大家有所帮助。
返回json数据中文显示的问题
解决方法一：
<?php
function Notice(){
include './include/conn.php'; //数据库链接文件
$sql_notice = mysql_query('SELECT * FROM gg_notice where enable = "1" limit 0,10');
$notice = mysql_fetch_array($sql_notice, MYSQL_ASSOC);
$str = json_encode($notice);
//linux
return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\\1'))", $str);
//windows
//return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2LE', 'UTF-8', pack('H4', '\\1'))", $str);
}
?>另外从网上搜索到的其他方法
<?php
/**
* json 生成,分析 支持中文
*/
class Json_Helper {
/**
* 生成json
*/
public static function encode($str){
$json = json_encode($str);
//linux
return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\\1'))", $json);
//windows
//return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2LE', 'UTF-8', pack('H4', '\\1'))", $json);
}
/**
* 分析json
*/
public static function decode($str) {
return json_decode($str);
}
}
?>这是从网上搜索得到的又一篇相关文章
当使用php自带的json_encode对数据进行编码时，中文都会变成unicode，导致不可读。如：对字符串”厦门“进行json_encode后，输出的是"\u53a6\u95e8"。
查询了一下，有两种方法：
1.将"\u53a6\u95e8"还原成“厦门”，使用如下的代码：
$str= preg_replace("#\\\u([0-9a-f]+)#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", $str);2.先将中文字段urlencode，json_encode后，再用urldecode，也可以显示中文。
$code = urldecode(json_encode(urlencode("厦门")));PHP5.4版本，已经给Json新增了一个选项: JSON_UNESCAPED_UNICODE。加上这个选项后，就不会自动把中文编码了。
echo json_encode("厦门", JSON_UNESCAPED_UNICODE);
另，由于 json_encode 和 json_decode只支持utf-8编码的字符，GBK的字符要用json就得转换一下，附自己写的GBK转UTF-8的代码：
/*
字符串GBK转码为UTF-8，数字转换为数字。
*/
function ct2($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"));相关推荐：
