Analyze and solve the problem of garbled characters when running PHP files from the cmd command line

With the development of Internet technology, PHP language has been widely used as a high-performance, flexible, easy-to-learn and easy-to-use server-side scripting language. In the actual development process, we usually use the command line (cmd) to run PHP files, but sometimes we encounter garbled characters when running PHP files from the command line. This article will introduce some workarounds.

1. Problem Analysis

When we use the cmd command line of the Windows system to run the PHP file, we sometimes find that Chinese characters are garbled. This situation is usually due to the fact that our operating system uses GBK encoding by default, while the PHP file itself is UTF-8 encoded.

2. Solution

1. Set the encoding of the cmd command line

First, we can try to solve the garbled problem by setting the encoding of the cmd command line .

After opening the cmd command line window, enter the following command:

chcp 65001

After executing the command, we need to restart the cmd command line window, and then run the PHP file again to see if Chinese still appears Garbled characters.

2. Convert the encoding of the PHP file

If the above method cannot solve the problem, we can try to convert the encoding of the PHP file to GBK encoding to make it consistent with the operating system default Coding is consistent.

We can use text editors such as Notepad to perform encoding conversion. The specific steps are as follows:

(1) Open the Notepad software.
(2) Select "File" - "Open" in the menu bar to open the PHP file that needs to be converted.
(3) Select "Encoding" - "Convert encoding to GBK" in the menu bar.
(4) Save the file and re-run the PHP file to check whether the problem of Chinese garbled characters has been solved.

3. Modify the encoding of the PHP file

If the above method still cannot solve the problem, we can try to directly modify the encoding of the PHP file to GBK encoding.

We can use text editors such as Notepad to make coding modifications. The specific steps are as follows:

(1) Open the Notepad software.
(2) Select "File" - "Open" in the menu bar to open the PHP file whose encoding needs to be modified.
(3) Select "Format"-"Convert to GBK" in the menu bar.
(4) Save the file and re-run the PHP file to check whether the problem of Chinese garbled characters has been solved.

4. Summary

This article introduces the solution to garbled PHP files running on the cmd command line, including setting the encoding of the cmd command line, converting the encoding of the PHP file, and modifying the encoding of the PHP file. Although each method has its advantages and disadvantages, in the actual development process, we can choose the most suitable solution according to the specific situation.
