What should I do if the PHP web page has Chinese garbled characters? A complete solution

The problem of Chinese garbled characters in PHP web pages is that Chinese characters are displayed as garbled characters in the web page display. This situation is usually caused by inconsistent encoding or the character set is not set. Solving the problem of Chinese garbled characters in PHP web pages requires starting from many aspects. The following are some common solutions and specific code examples.

Set the PHP file encoding: First make sure that the encoding of the PHP file itself is UTF-8. You can set the UTF-8 encoding when saving in the editor, or add the following code settings in the header of the PHP file. Encoding:

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

Copy after login

Set MySQL database encoding: If the PHP webpage reads data from the database and displays garbled characters, it may be caused by inconsistent database encoding. When connecting to the database, you can set the encoding of the MySQL database to UTF-8. The example is as follows:

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

Set the web page header information: add the meta tag to the web page and set the character set to UTF- 8. To ensure that the browser correctly parses the Chinese content in the web page, the example is as follows:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>解决PHP网页中文乱码问题</title>
</head>
<body>

Copy after login

Convert the encoding of the output content: Sometimes the content read directly from the database or external file may When using different encodings, you need to perform encoding conversion before displaying. The example is as follows:

// 从数据库中读取内容并进行编码转换
$data = $mysqli->query("SELECT content FROM table")->fetch_assoc();
$content = mb_convert_encoding($data['content'], 'UTF-8', 'gbk');

// 输出内容
echo $content;

Copy after login

Use the iconv function to convert character encodings: With the help of the iconv function, you can easily convert between various character sets. The conversion between, examples are as follows:

$text = "乱码内容";
echo iconv("GB2312", "UTF-8//IGNORE", $text);

Copy after login

Through the above method, the problem of Chinese garbled characters in PHP web pages can be effectively solved, ensuring that Chinese content can be displayed correctly on the web page. In actual development, appropriate solutions are selected according to specific circumstances to solve the problem of Chinese garbled characters and ensure accurate display of web page content.
