When configuring php.ini in a Linux system, sometimes you will often encounter garbled characters when opening the file. This situation is usually caused by encoding mismatch. Today we will discuss how to solve the problem of garbled characters when opening php.ini in Linux systems.

The main reasons for garbled characters when opening the php.ini file in a Linux system are as follows:

1. Use an editor that supports automatic identification of encoding formats. It is recommended to use editors such as Sublime Text and Notepad. These editors have the function of automatically identifying the encoding format when opening a file, and can change the encoding format to display the file content in a timely manner.

2. Use a text editor that supports file encoding conversion. These editors can convert PHP.ini files to other encoding formats, such as converting PHP.ini files in ISO-8859-1 format to UTF-8 format.

3. Use command line tools to view the file contents. In Linux systems, you can use the following command to view the contents of the PHP.ini file:

cat /etc/php.ini

This command can view the contents of the PHP.ini file in the terminal without being interfered by any text editor and can be effective Avoid garbled characters.

4. Summary

When opening the PHP.ini file in a Linux system, the garbled characters are usually caused by encoding mismatch, using the wrong text editor or file damage.
