PHP如何解决JSON中文显示问题?本文主要介绍了PHP JSON格式的中文显示问题解决方法,本文总结了3种解决中文显示\u开头字符问题的方法。希望对大家有所帮助。
返回json数据中文显示的问题
解决方法一:
<?php function Notice(){ include './include/conn.php'; //数据库链接文件 $sql_notice = mysql_query('SELECT * FROM gg_notice where enable = "1" limit 0,10'); $notice = mysql_fetch_array($sql_notice, MYSQL_ASSOC); $str = json_encode($notice); //linux return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\\1'))", $str); //windows //return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2LE', 'UTF-8', pack('H4', '\\1'))", $str); } ?>
另外从网上搜索到的其他方法
<?php /** * json 生成,分析 支持中文 */ class Json_Helper { /** * 生成json */ public static function encode($str){ $json = json_encode($str); //linux return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\\1'))", $json); //windows //return preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2LE', 'UTF-8', pack('H4', '\\1'))", $json); } /** * 分析json */ public static function decode($str) { return json_decode($str); } } ?>
这是从网上搜索得到的又一篇相关文章
当使用php自带的json_encode对数据进行编码时,中文都会变成unicode,导致不可读。如:对字符串”厦门“进行json_encode后,输出的是"\u53a6\u95e8"。
查询了一下,有两种方法:
1.将"\u53a6\u95e8"还原成“厦门”,使用如下的代码:
$str= preg_replace("#\\\u([0-9a-f]+)#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", $str);
2.先将中文字段urlencode,json_encode后,再用urldecode,也可以显示中文。
$code = urldecode(json_encode(urlencode("厦门")));
PHP5.4版本,已经给Json新增了一个选项: JSON_UNESCAPED_UNICODE。加上这个选项后,就不会自动把中文编码了。
echo json_encode("厦门", JSON_UNESCAPED_UNICODE);
另,由于 json_encode 和 json_decode只支持utf-8编码的字符,GBK的字符要用json就得转换一下,附自己写的GBK转UTF-8的代码:
/* 字符串GBK转码为UTF-8,数字转换为数字。 */ function ct2($s){ if(is_numeric($s)) { return intval($s); } else { return iconv("GBK","UTF-8",$s); } } /* 批量处理gbk->utf-8 */ function icon_to_utf8($s) { if(is_array($s)) { foreach($s as $key => $val) { $s[$key] = icon_to_utf8($val); } } else { $s = ct2($s); } return $s; } echo json_encode(icon_to_utf8("厦门"));

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
