Summary of methods to solve the problem of garbled Chinese names displayed in PHP

In web development, we often encounter the problem of garbled Chinese names, especially in PHP. Since the character set used by PHP by default may not be UTF-8, garbled characters are prone to appear when processing Chinese characters. This article will summarize several methods to solve the problem of garbled Chinese names displayed in PHP and provide specific code examples.

Set file encoding

First of all, make sure that the encoding of the PHP file itself is UTF-8. You can set the encoding format to UTF-8 Without BOM in the code editor. . This prevents the PHP parser from causing garbled characters when processing files.

<?php
header('Content-Type: text/html; charset=utf-8');
?>

Copy after login

Set database connection encoding

If the PHP program needs to connect to the database, it is recommended to set the encoding to UTF-8 when connecting to the database to ensure the normal transmission of Chinese data and display.

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

Copy after login

Set page encoding

When outputting an HTML page, set the page encoding to UTF-8.

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Chinese garbled problem</title>
</head>
<body>
<?php
echo "Hello, world!";
?>
</body>
</html>

Copy after login

Use the mb_convert_encoding function

If garbled characters appear when processing Chinese strings in PHP, you can use the mb_convert_encoding function to perform encoding conversion.

<?php
$str = "Chinese garbled characters";
$str_utf8 = mb_convert_encoding($str, "UTF-8");
echo $str_utf8;
?>

Copy after login

Set HTTP header information

Before PHP outputs the content, you can use the header function to set the HTTP header information and specify the content type and encoding.

<?php
header('Content-Type: text/html; charset=utf-8');
echo "Hello, world!";
?>

Copy after login

Through the above methods, you can effectively solve the problem of PHP displaying garbled Chinese names. When writing PHP programs, be sure to pay attention to the consistency of character encoding to avoid garbled characters.
