PHP is a widely used server-side scripting language that can handle functions such as dynamic web content generation, file operations, and database connections. However, sometimes when using PHP to write web pages, the problem of garbled Chinese characters may occur. The cause of garbled characters is usually incorrect character encoding settings or problems that may be caused by database connections. The following are some methods to solve the problem of garbled Chinese characters displayed on PHP web pages.

1. Check the file encoding

Make sure that the encoding of the PHP file is consistent with the encoding of the web page. Common encoding formats are UTF-8 and GBK. You can add the following code at the beginning of the code to define the file encoding:

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

2. Check the database connection encoding

If the web page content comes from the database, you need to ensure that the database connection encoding is consistent with The web page encoding is consistent. You can use the following code to set the database connection encoding:

mysqli_set_charset($conn, "utf8");

Here `$conn` is the database connection object.

3. Set the web page encoding

Add the following code in the `` tag of the web page to set the web page encoding:

<meta charset="UTF-8">

4. Convert the encoding of the output content

If the database connection encoding and the web page encoding cannot be consistent, you can use the `iconv()` or `mb_convert_encoding()` function to encode the output content. . For example:

$content = iconv("gbk", "utf-8", $content);
echo $content;

or

$content = mb_convert_encoding($content, "utf-8", "gbk");
echo $content;

The `$content` here is the content that needs to be converted.

5. Check the database encoding

If the web page content comes from the database, you need to check the encoding settings of the database. This can be confirmed by querying the database for encoding. For example, in MySQL, you can use the following SQL statement to query the encoding of the database:

SHOW VARIABLES LIKE 'character_set_database';

Make sure that the encoding setting of the database is consistent with the encoding of the web page.

Summary

The above are some common methods to solve the problem of Chinese display garbled characters in PHP web pages. By checking the file encoding, database connection encoding, and web page encoding, and then performing corresponding encoding conversions, the problem of garbled Chinese display can be solved. When writing PHP web pages, it is important to maintain consistent encoding settings to ensure that the web content can display Chinese correctly.
