PHP生成JSON相关的问题
关于PHP生成JSON数据的几个问题。
<code>foreach($re as $key=>$value){ $dd['code'][0]->$key=$value; } $ff = json_encode($dd); print_r($ff); // 输出 {"code":[{"0":{"key":"value"},"1":{"key":"value"}}]}</code>
请问要怎么在code前现加一点内容呢?比如:"url":"www.com"
,使生成的JSON就成这样。
<code>{"url":"www.com", "code":{"0":{"key":"value"},"1":{"key":"value"}}}}</code>
还就是输出的中文全变成了这样\u8f8a\u67e5\u538d
,要怎么才能输出成中文呢?
Google了半天都没找到办法,找到的基本全这样的。
<code>$aa = urlencode($dd); echo urldecode(json_encode($aa));</code>
可是这样不仅不能输出中文,连输出都没有了。。。
var_dump($aa)输出的是NULL
,这可怎么办是好啊。。
=============追加=================
那个出现个问题。
<code>{ "url":"www.com", "0": { "code": { "0":{"key":"value"}, "1":{"key":"value"} } } }</code>
生成的JSON会变成这样子,请问要怎么把这此数字去掉呢?
=================二追===================
<code>$aa = array("url"=>"www.com"); json_encode(array($aa,$dd['code']), JSON_UNESCAPED_UNICODE);</code>
这样能可以实现想要的,可是有个问题。
从Mysql导出来的数据时怎么会有一个序号呢?

你的问题有两个:
1,如何追加内容?
json 和 array 是对应的,就像你给数据追加内容一样:
$url = 'www.com'; $code = array( array('key', 'value'); array('key', 'value'); array('key', 'value'); ); echo json_encode(array('url'=>$url, 'code'=>$code));
2,如何不乱码?
php5.4 之后 json 新增了一个选项 JSONUNESCAPEDUNICODE:
echo json_encode(array('url'=>$url, 'code'=>$code), JSON_UNESCAPED_UNICODE);
让 json 更懂中文
要在code
前加上内容,可以在要转换为json
的数组前加上值就可以了吧。-_-
$dd['url'] = 'www.xx.com';
PHP版本始于5.4后可用JSON_UNESCAPED_UNICODE
参数常量来将字符不转换为unicode
码,具体参考手册。
$ff = json_encode($dd, JSON_UNESCAPED_UNICODE);
如果PHP版本小于5.4,可参考如下方法:
function json_encode_utf8($value) { $jsons = json_encode($value); return preg_replace( "#\\\u([0-9a-f]{4}+)#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", $jsons ); }
\u8f8a\u67e5\u538d
本身就是中文啊, 这个是交给前端处理的。
问题1:
<code>$dd['url'] = 'www.com'; $dd['code'] = array();</code>
问题2:
见1楼,那个是js中推荐的汉字使用方式,与文件编码无关。js中直接使用

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP?
