How to solve Chinese garbled settings in thinkphp

ThinkPHP is an excellent PHP framework that is widely used in the development of web applications. However, during the development process using ThinkPHP, it is easy for the problem of Chinese garbled characters to occur. This article will introduce how to solve the problem of Chinese garbled characters under the ThinkPHP framework.

1. Character set setting

In the ThinkPHP framework, you can set the character set in the config.php file in the application directory. Search for the 'charset' keyword in the file and you can find the following content:

'charset'  => 'utf-8',

As you can see, the default character set of ThinkPHP is utf-8. If the character set is specified in the meta tag of the page in the browser, it needs to be consistent. For example, if the character set is GB2312 specified in the HTML code, then you need to set the character set to GB2312 in config.php:

'charset'  => 'GB2312',

2. Database operation character set setting

When using ThinkPHP for database operations, you need to set the character set of the database. It can be set in the database.php file:

'charset'   =>  'utf8',

If the character set set by the database is inconsistent with the character set set by the framework, then corresponding adjustments need to be made.

3. File encoding

When using the ThinkPHP framework to write files, you need to keep the file encoding consistent with the character set set by the framework. If UTF-8 encoding is used, the beginning of the file should be set to:

header("Content-type: text/html; charset=utf-8");

This sentence can ensure that the output content is UTF-8 encoded.

4. Database table settings

When using the ThinkPHP framework for database operations, you need to set the character set of the corresponding data table. You can use the charset parameter in the table creation statement, for example:

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(20) NOT NULL COMMENT '用户名',
  `password` varchar(50) NOT NULL COMMENT '密码',
  `email` varchar(50) NOT NULL COMMENT '邮箱',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户表';

You can see that the character set specified in the table creation statement is utf-8.

5. Chinese encoding format conversion

Sometimes, we need to convert from GB2312 encoding format to utf-8 encoding format, or vice versa. You can use the iconv() function for conversion:

iconv("utf-8","gb2312",$str);
iconv("gb2312","utf-8",$str);

This way you can convert between different encoding formats.

Summary:

When using ThinkPHP for development, the problem of Chinese garbled characters is often caused by incorrect character set settings. By making appropriate adjustments and settings in the above five aspects, the problem of Chinese garbled characters can be well solved.
