Solution to Chinese display problem in PHP JSON format

返回json數(shù)據(jù)中文顯示的問題

上一篇文章中,返回json格式的中文顯示成\u5723\u8bde\u8282\u5343\u4e07\u597d\u793c\u5927\u5949\u9001

解決方法一:

<?php 
function Notice(){
    include &#39;./include/conn.php&#39;;  //數(shù)據(jù)庫鏈接文件
    $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);
    
}
?>

另外從網(wǎng)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);
    }
}
?>

這是從網(wǎng)上搜索得到的又一篇相關(guān)文章

當(dāng)使用php自帶的json_encode對(duì)數(shù)據(jù)進(jìn)行編碼時(shí),中文都會(huì)變成unicode,導(dǎo)致不可讀。如:對(duì)字符串”廈門“進(jìn)行json_encode后,輸出的是"\u53a6\u95e8"。

查詢了一下,有兩種方法:
1.將"\u53a6\u95e8"還原成“廈門”,使用如下的代碼:

$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);

2.先將中文字段urlencode,json_encode后,再用urldecode,也可以顯示中文。

$code = urldecode(json_encode(urlencode("廈門")));

PHP5.4版本,已經(jīng)給Json新增了一個(gè)選項(xiàng): JSON_UNESCAPED_UNICODE。加上這個(gè)選項(xiàng)后,就不會(huì)自動(dòng)把中文編碼了。

echo json_encode("廈門", JSON_UNESCAPED_UNICODE);

另,由于 json_encode 和 json_decode只支持utf-8編碼的字符,GBK的字符要用json就得轉(zhuǎn)換一下,附自己寫的GBK轉(zhuǎn)UTF-8的代碼:

/*
    字符串GBK轉(zhuǎn)碼為UTF-8,數(shù)字轉(zhuǎn)換為數(shù)字。
*/
function ct2($s){
    if(is_numeric($s)) {
        return intval($s);
    } else {
        return iconv("GBK","UTF-8",$s);
    }
}
/*
    批量處理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("廈門"));
