HomeBackend DevelopmentPHP TutorialSolution to the problem of Chinese UNICODE transcoding in json_encode in php

我们在之前的文章中给大家介绍了php中json_encode()函数的详解以及使用方法、在我们工作会用到json_encode来处理中文的时候, 中文都会被编码, 变成不可读的, 类似”\u***”的格式,如果想汉字不进行转码,这里提供三种方法解决json_encode中文UNICODE转码的问题!

1.升级PHP,在PHP5.4, 这个问题终于得以解决, Json新增了一个选项: JSON_UNESCAPED_UNICODE, 故名思议, 就是说, Json不要编码Unicode.

<?php
echo json_encode("中文", JSON_UNESCAPED_UNICODE);
//"中文"

2.把汉字先urlencode然后再使用json_encode,json_encode之后再次使用urldecode来解码,这样编码出来的json数组中的汉字就不会出现unicode编码了。

$array = array(
&#39;test&#39;=>urlencode("我是测试")
);
$array = json_encode($array);
echo urldecode($array);
//{"test":"我是测试"}

3.对unicode码再进行解码,解码函数如下:

function decodeUnicode($str)
{
    return preg_replace_callback(&#39;/\\\\u([0-9a-f]{4})/i&#39;,
        create_function(
            &#39;$matches&#39;,
            &#39;return mb_convert_encoding(pack("H*", $matches[1]), "UTF-8", "UCS-2BE");&#39;
        ),
        $str);
}

4.例子

$arr = array(&#39;name1&#39;:"中文",&#39;name2&#39;:&#39;abc12&#39;);
$jsonstr = decodeUnicode(json_encode($arr));

总结:

本文通过三种方法解决了php中json_encode中文UNICODE转码的问题,相信小伙伴在遇到相同的问题可以轻松的解决了!
