php转义汉字的解决办法:1、使用自定义的“function json_encode_ex($value)”方法实现中文不转义;2、通过“JSON_UNESCAPED_UNICODE”选项实现不转义;3、使用urldecode来解码。

本文操作环境:windows7系统、PHP7.1版,DELL G3电脑

php实现json_encode()中文字符不转义

在项目中,php提供的接口使用json_encode()函数,在处理中文的时候, 中文都会被编码成Unicode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

1.php版本在5.3及以下自己写函数实现中文不转义

function json_encode_ex($value)
{
    if(version_compare(PHP_VERSION,&#39;5.4.0&#39;,&#39;<&#39;)){
        $str = json_encode($value);
        $str = preg_replace_callback(
                                    "#\\\u([0-9a-f]{4})#i",
                                    function($matchs)
                                    {
                                         return iconv(&#39;UCS-2BE&#39;, &#39;UTF-8&#39;, pack(&#39;H4&#39;, $matchs[1]));
                                    },
                                     $str
                                    );
        return $str;
    }else{
        return json_encode($value, JSON_UNESCAPED_UNICODE);
    }
}
echo json_encode_ex($arr);
Copy after login

2.php版本5.4以上,json_encode()新增了一个选项,JSON_UNESCAPED_UNICODE 意思是json不要unicode编码

echo json_encode($arr,JSON_UNESCAPED_UNICODE);
Copy after login

3.先把中文汉字进行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

$arr = array(
    &#39;key&#39;=>urlencode("测试")
);
$json = json_encode($arr);
echo urldecode($json);
//{"key":"测试"}
Copy after login
