php中json_encode gbk/gb2312中文乱码
php中json_encode gbk/gb2312中文乱码
1.json_encode()中文在gbk/gb2312中中文返回为null
代码如下 | |
$arr = array ( array ( 'catid' => '4', 'catname' => 'www.111cn.net', 'meta_title' => '一聚教程网2' ) 结果 [{"catid":"4","catname":"www.111cn.net","meta_title":null}] |
看一了吗"meta_title":null 他本来是有一个值的为一聚教程网2了,这个我们查了一下原理是json_encode只支持uft-8编码,我们转换一下
代码如下 | |
$data=”JSON中文”; $newData=iconv(“GB2312″,”UTF-8//IGNORE”,$data); echo $newData; //ignore的意思是忽略转换时的错误,如果没有ignore参数,所有该字符后面的字符都不会被保存。 //或是(“GB2312″,”UTF-8″,$data); ?> |
Step2
后台PHP页面(页面编码为UTF-8或者已经把字符转为UTF-8)使用json_encode将PHP中的array数组转为JSON字符串。例如:
代码如下 | |
$testJSON=array(‘name’=>’中文字符串’,’value’=>’test’); echo json_encode($testJSON); ?> 查看输出结果为: {“name”:”u4e2du6587u5b57u7b26u4e32″,”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:
代码如下 | |
$testJSON=array(‘name’=>’中文字符串’,’value’=>’test’); 查看输出结果为: {“name”:”中文字符串”,”value”:”test”} |
总结:json_encode函数只能处理uft8字符串,如果是中文估计是对字节处理不好,因为中文gbk与uft长度是不一样的哦,这个我也不深入介绍了。

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,

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i.

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? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
