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.


      

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( 'test'=>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($str) { return preg_replace_callback('/\\\\u([0-9a-f]{4})/i', create_function( '$matches', 'return mb_convert_encoding(pack("H*", $matches[1]), "UTF-8", "UCS-2BE");' ), $str); }

4.例子

$arr = array('name1':"中文",'name2':'abc12'); $jsonstr = decodeUnicode(json_encode($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!
