Solution to the garbled problem of PHPShellUnrar

PHPShellUnrar is a commonly used decompression tool. During use, garbled characters may sometimes be encountered. In this article, we will discuss this problem and provide some solutions.

Problem description

When using PHPShellUnrar, if the decompressed file name or path contains Chinese characters, sometimes garbled characters will appear. This situation is more annoying because garbled characters will affect the effectiveness of decompression.

Solution

1. Use the correct character encoding

First, we need to confirm whether the character encoding used is correct. If your operating system uses UTF-8 by default, PHPShellUnrar should also need to use UTF-8 encoding to decompress. You can try to set the correct character set using the following command in PHPShell before decompressing:

mb_internal_encoding("UTF-8");

This will tell PHPShellUnrar to use UTF-8 encoding to decompress the file.

2. Modify the source code of PHPShellUnrar

If the first method fails to solve the problem, you can try to modify the source code of PHPShellUnrar. Specifically, you need to find the following code in the PHPShellUnrar.php file:

$filename = iconv('UTF-8','GB2312',$filename);

Change it to:

$filename = iconv('UTF-8','UTF-8//IGNORE',$filename);

This will tell PHPShellUnrar to ignore parsing illegal UTF-8 characters. Please note that this approach may cause illegal characters in the decompressed file name or path to be removed or converted.

3. Modify the default character encoding of the operating system

If the default character encoding of your operating system is not UTF-8, then you can try to modify its default encoding. Specifically, you can refer to the relevant documentation of your operating system, but please note that modifying the default encoding of the operating system may affect other software.

4. Use other decompression tools

Finally, if none of the above methods work, you can try using other decompression tools. Although this is not the best solution, it may solve your problem.

Summary

PHPShellUnrar garbled problem may be caused by a variety of reasons. This article provides some common solutions, such as correctly setting the character encoding, modifying the source code, modifying the operating system default encoding, and you can also choose to use other decompression tools. Through these methods, you should be able to effectively solve the PHPShellUnrar garbled problem.
