HomeBackend DevelopmentPHP Tutorial Mysql取出来的中文是5位utf编码怎么处理

Mysql取出来的中文是5位utf编码怎么办?
用php取mysql的值,在网页里看是,中文是5位utf8的编码,不是中文字.
请问是怎么回事?

mysql运行show variables like '%char%';结果如下
character_set_client utf8
character_set_connection utf8
character_set_database utf8
character_set_filesystem binary
character_set_results utf8
character_set_server utf8
character_set_system utf8

php这么写的
$conn = mysql_connect("localhost", "root", "1");
mysql_select_db("123", $conn);
mysql_query("set names 'utf8'");
$sql = "select * from 123.abc";
$result = mysql_query($sql);
$res1= mysql_fetch_array ( $result, MYSQL_NUM) ;
echo json_encode ( $res1 );
mysql_close($conn);
------解决方案--------------------
\u4e2d 这个形式吧?

这是 json_encode 处理的结果,不影响 php、js 使用
在 json_encode 之前依然是汉字

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
