How to solve the Chinese garbled characters of json_decode function in PHP?

Solution to the Chinese garbled code of the json_decode function in PHP: 1. Use the function "urldecode()" to decode the data, and then perform JSON decoding after decoding. The function of its function is to decode the encoded URL string; 2. , When encoding JSON, just do not encode Chinese.

Sample code

<?php
    $testJSON=array(&#39;name&#39;=>&#39;中文字符串&#39;,&#39;value&#39;=>&#39;test&#39;);
    echo json_encode($testJSON);
?>

查看输出结果为：
{“name”:”\u4e2d\u6587\u5b57\u7b26\u4e32″,”value”:”test”}
可见即使用UTF8编码的字符，使用json_encode也出现了中文乱码。解决办法是在使用json_encode之前把字符用函数urlencode()处理一下，然后再json_encode，输出结果的时候在用函数urldecode()转回来。具体如下：


<?php
    $testJSON=array(&#39;name&#39;=>&#39;中文字符串&#39;,&#39;value&#39;=>&#39;test&#39;);
    //echo json_encode($testJSON);
    foreach ( $testJSON as $key => $value ) {
        $testJSON[$key] = urlencode ( $value );
    }
    echo urldecode ( json_encode ( $testJSON ) );
?>


查看输出结果为：



{“name”:”中文字符串”,”value”:”test”}
