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.
1. Understand the php.ini file
First of all, we need to understand what the php.ini file is. The php.ini file is the configuration file of the PHP interpreter, which mainly includes PHP core configuration information, such as memory size, uploaded file size, script execution time, etc.
2. Reasons for garbled characters
The main reasons for garbled characters when opening the php.ini file in a Linux system are as follows:
1. Coding mismatch. The default encoding of the PHP.ini file is ISO-8859-1, and the encoding commonly used in Linux systems is UTF-8. If the text editor used does not support automatic recognition of the encoding format, garbled characters will appear.
2. Use the wrong text editor. If the text editor used does not support the encoding format of the PHP.ini file, garbled characters will appear.
3. The file is damaged. If the PHP.ini file itself is damaged or infected by a virus, garbled characters will appear.
3. Solution
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. In order to avoid this situation, we can use an editor that supports automatic identification of encoding formats, a text editor that supports file encoding conversion, or use a command line tool to view the file content.
