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 &#39;./include/conn.php&#39;;  //数据库链接文件
    $sql_notice = mysql_query(&#39;SELECT * FROM gg_notice where enable = "1" limit 0,10&#39;);
    $notice = mysql_fetch_array($sql_notice, MYSQL_ASSOC);
    $str = json_encode($notice);
    //linux
    return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv(&#39;UCS-2BE&#39;, &#39;UTF-8&#39;, pack(&#39;H4&#39;, &#39;\\1&#39;))", $str);
    //windows
    //return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv(&#39;UCS-2LE&#39;, &#39;UTF-8&#39;, pack(&#39;H4&#39;, &#39;\\1&#39;))", $str);
    
}
?>
Copy after login

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(&#39;UCS-2BE&#39;, &#39;UTF-8&#39;, pack(&#39;H4&#39;, &#39;\\1&#39;))", $json);
        //windows
        //return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv(&#39;UCS-2LE&#39;, &#39;UTF-8&#39;, pack(&#39;H4&#39;, &#39;\\1&#39;))", $json);
    }
    /**
     * 分析json
     */
    public static function decode($str) {
        return json_decode($str);
    }
}
?>
Copy after login

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(&#39;UCS-2&#39;, &#39;UTF-8&#39;, pack(&#39;H4&#39;, &#39;\\1&#39;))", $str);
Copy after login

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")));
Copy after login

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);
Copy after login


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"));
Copy after login
