What should I do if garbled characters appear when running php in cmd?

It is a very common problem that garbled characters appear when running PHP in cmd. Many PHP developers may encounter this problem. This problem usually occurs due to reasons such as inconsistent coding or missing necessary configuration files.

In this article, we will introduce some common causes and solutions so that you can easily solve the garbled code problem when running php in cmd.

1. Garbled characters caused by inconsistent encoding

When running the PHP program in cmd, the encoding used may be inconsistent with your program encoding, which will cause you to see garbled characters in the console.

Solution: Use the "chcp" command in cmd (for example, chcp 65001) to change the console encoding to resolve this issue. This command will change the encoding of cmd to UTF-8 (65001 is the UTF-8 encoding number). After changing the encoding you should be able to see the correct output.

2. Garbled characters caused by the lack of php.ini configuration file

In some cases, the lack of php.ini configuration file may also be one of the reasons for garbled characters when running the php program in cmd one.

Solution: You can copy the php.ini-development file (or php.ini-production file) in the php folder and rename it to php.ini. Then, copy the file to your working directory (you can also place it in the PHP installation directory). By doing this you should be able to properly set all the necessary configuration properties to better support PHP encoding.

3. Garbled characters caused by other possible reasons

There are some other reasons that may also cause garbled characters when running php in cmd. Here are some solutions:

1. Make sure all components you use support UTF-8 encoding.
2. Set the locale environment variable in cmd, such as set LC_ALL=C.UTF-8.
3. Change the command line font to TrueType font.
4. Use Windows PowerShell instead of cmd to run php programs.

Conclusion

Garbled characters when running PHP programs in cmd is a common problem, but it is not difficult to solve. If you encounter this problem, you can first try changing the console encoding and then check if the necessary configuration files are missing. If the problem persists, try other solutions, such as setting the locale environment variable or changing the font. By trying these simple solutions, you should soon be able to avoid garbled characters when running PHP programs in cmd.
