PHP Chinese character encoding processing skills sharing

In Web development, especially when it comes to Chinese character processing, character encoding is often a common problem. Correctly handling Chinese character encoding can avoid problems such as garbled characters and improve the user experience of the website. In PHP, we can use some techniques to handle Chinese character encoding. Below we will share some practical processing methods and code examples.

1. Set the PHP file encoding

First of all, make sure that the encoding of the PHP file itself is correct. It is generally recommended to use UTF-8 encoding. Add the following code to the beginning of the PHP file to specify the encoding:

header('Content-Type: text/html; charset=UTF-8');

2. Processing String encoding conversion

When processing data passed from the front end, encoding conversion is often required, such as converting GBK-encoded strings into UTF-8 encoding. You can use the following code:

$gbk_str = "Chinese string"; $utf8_str = iconv("GBK", "UTF-8", $gbk_str); echo $utf8_str;

3. URL encoding and decoding

When passing a URL containing Chinese characters, URL encoding and decoding is required. You can use the following code example:

$original_url = "http://example.com/search.php?keyword=中文"; $encoded_url = urlencode($original_url); echo $encoded_url; $decoded_url = urldecode($encoded_url); echo $decoded_url;

4. Database storage Chinese character processing

When storing Chinese characters in the database, make sure that the encoding setting of the database is correct. It is generally recommended to use UTF-8 encoding. You can add the following code to set the encoding when connecting to the database:

$mysqli = new mysqli("localhost", "username", "password", "dbname"); $mysqli->set_charset("utf8");

5. Output JSON data processing

If you need to output JSON data containing Chinese characters, make sure to To encode characters, you can use the following code example:

$data = ['Chinese' => 'Test']; echo json_encode($data, JSON_UNESCAPED_UNICODE);

The above are some common techniques and code examples for processing Chinese character encoding. They can be flexibly applied according to specific needs in actual projects to ensure that Chinese characters are processed correctly and improve the website. reliability and user experience. I hope these tips can help you better deal with Chinese character encoding issues in PHP.
