本文列举3个方法,实现json_encode()后的string显示中文问题。
做接口时不需要,但存log时帮了大忙了。
在贴代码前,必须贴上官方param和return,链接:http://php.net/manual/zh/function.json-encode.php
参数
value
-
待编码的
value
,除了resource 类型之外,可以为任何数据类型该函数只能接受 UTF-8 编码的数据

,JSON_HEX_APOS
,JSON_NUMERIC_CHECK
,JSON_PRETTY_PRINT

<?php // json_encode() 保持中文方法详解 $arr['city'] = '北京'; $arr['name'] = 'weilong'; // 直接输出 // Res: {"city":"\u5317\u4eac","name":"weilong"} echo json_encode($arr), "\n"; #### 1. 加参数,PHP版本>=5.4 // Res: {"city":"北京","name":"weilong"} echo json_encode($arr, JSON_UNESCAPED_UNICODE), "\n"; // php >= 5.4 #### 2. 正则替换,json_encode后,正则将编码替换成中文 // Res: {"city":"北京","name":"weilong"} echo preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\\1'))", json_encode($arr)), "\n"; // PHP 5.5 /e修饰符被弃用 echo preg_replace_callback("/\\\u([0-9a-f]{4})/i", function($match) { // php >= 5.3 都可以 return json_decode("\"{$match[0]}\"", true); }, json_encode($arr)), "\n"; #### 3. urldecode()、urlencode()函数,不推荐 // Res1: null, Res2: {"city":"北京","name":"weilong"} echo urldecode(json_encode(urlencode($arr))), "\n"; $arr['city'] = urlencode($arr['city']); // urlencode()参数必须是string echo urldecode(json_encode($arr)), "\n"; // 另外注意json_decode()参数区别。 $arr['city'] = '北京'; $arr['name'] = 'weilong'; $str = json_encode($arr); $str2 = json_decode($str); $str3 = json_decode($str, true); print_r($str2); // object /* Res: stdClass Object ( [city] => 北京 [name] => weilong ) */ print_r($str3); // array /* Res: Array ( [city] => 北京 [name] => weilong ) */

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,
