Analyze why the php file is garbled when opened

In our daily programming work, we will inevitably encounter various problems, one of which is garbled characters when opening PHP files. This situation has brought great trouble to our work. This article will discuss the reasons and solutions for garbled characters when opening PHP files.

1. Encoding issues

A very common reason why PHP files are garbled when opened is the encoding format problem. When we write PHP files, we may use different encoding formats due to habits or other reasons, which results in garbled characters when the files are opened in different systems or software.

Solution:

1. Modify the encoding format in the editor

We can change the encoding format of the file to UTF-8, save it and try again to see if it works normally. Open.

2. Setting the Content-Type of HTTP

can be solved by modifying the content-type of HTTP in the PHP file, for example:

header("Content-type: text/html; charset=utf-8");

2. File format problems

File format problems are somewhat similar to encoding problems, but they are easier to solve than encoding problems. Under normal circumstances, the format of the php file should be .php, but if we select other formats when saving, it may cause garbled characters when opening.

Solution:

1. Modify the file format

Change the file format to .php, save it and try again to see if it can be opened normally.

3. Server configuration issues

The reason why the PHP file opens with garbled characters may also be a server configuration issue. It may be that the server does not correctly configure the relevant encoding settings, causing the web page to be unable to recognize the encoding.

Solution:

1. Check the server configuration

At this time we can check the server configuration file, such as php.ini, to see if the relevant encoding settings are correct. .

2. Set HTTP header information

Set HTTP header information in the PHP file and determine the encoding format, for example:

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

In short, when the PHP file is garbled when opening it, we should first clarify the cause of the garbled code, and then adopt targeted solutions to ensure that our code and work can normal operation.
