The solution to the garbled code on the phpcms login page is: 1. Add the "header("Content-type:text/html;charset=utf-8")" code at the beginning of the PHP file, and replace utf-8 with The current website uses characters, then in phpMyAdmin, enter the "Operation" tab, select "Character Set", and set it to UTF-8; 2. Change the code editor or IDE and try to save as "UTF-8 without BOM" .
The operating system of this tutorial: Windows 10 system, phpcms v9 version, Dell G3 computer.
The reason for garbled codes may be one of the following situations:
Different encoding formats are used in the code, causing the page to display garbled codes.
The database character encoding and the PHP file character encoding are inconsistent, resulting in garbled pages.
The header of the web page declares an incorrect charset, causing a browser parsing error.
To solve this problem, you can try the following methods:
1. Make sure that both the PHP file and the database use the same character encoding.
In PHP Add the following code at the beginning of the file: `header("Content-type:text/html;charset=utf-8");` (If your website uses the GB2312 character set, please replace utf-8 with GB2312); In addition, In phpMyAdmin, enter the "Operation" tab, select "Character Set", and set it to UTF-8;
2. If you have determined that the database and PHP character encodings are the same, but garbled characters still occur , you can consider changing the code editor or IDE. Some editors may automatically add BOM characters, causing the page to be garbled. In an editor such as Notepad or Sublime Text, you can try saving as "UTF-8 without BOM".
Here is a simple sample code to solve this problem:
<?php header('Content-Type: text/html; charset=utf-8'); ?>
<html>
<head>
<meta charset="utf-8">
<title>登录页面</title>
</head>
<body>
<form action="" method="post">
用户名：<input type="text" name="username"><br/>
密码： <input type="password" name="password"><br/>
<input type="submit" name="submit" value="登录">
</form>
</body>
</html>In this example, we added the header() function at the beginning of the PHP file to declare the document type and character set, and Specifies the charset of the HTML header to be UTF-8. This ensures that the same encoding method is used throughout the entire process, and there will be no garbled code problems at runtime.
