In PHP files, the first step in fixing Chinese encoding issues is to correctly set the file encoding to UTF-8. You can ensure the file is processed in UTF-8 encoding by adding the following code at the beginning of your PHP file:
header('Content-Type: text/html; charset=UTF-8');When interacting with a database, it's crucial to ensure that the database connection uses UTF-8 encoding. The following code demonstrates how to set the database connection encoding to UTF-8 in PHP:
$conn = new mysqli($servername, $username, $password, $dbname);<br>$conn->set_charset('utf8');When receiving Chinese data from a form submission, you can use the mb_convert_encoding function to convert it to UTF-8 encoding, preventing garbled characters:
$name = $_POST['name'];<br>$name = mb_convert_encoding($name, 'UTF-8', 'auto');When outputting Chinese characters to the page, ensure that the character encoding is correct and use mb_convert_encoding for conversion. Here's an example of how to output Chinese characters:
echo mb_convert_encoding($text, 'HTML-ENTITIES', 'UTF-8');When reading or writing files, make sure the file encoding is set to UTF-8. The following code shows how to read a file and convert its encoding:
$fileContent = file_get_contents('file.txt');<br>$fileContent = mb_convert_encoding($fileContent, 'UTF-8', 'auto');For Chinese characters in URLs, you should use the urlencode and urldecode functions for encoding and decoding, avoiding garbled characters:
$url = 'http://example.com?name=' . urlencode($name);<br>$name = urldecode($_GET['name']);By following these tips, you can effectively solve PHP Chinese encoding errors and ensure proper display of Chinese characters in various operations. Choose the appropriate encoding conversion method based on the specific needs of your project to maintain data integrity and accuracy.
