RasPi / Win10 PHP filenames (cifs) charset
When working with filenames on a Raspberry Pi (RasPi) using Windows 10 and PHP, you might encounter issues with character encoding due to differences in the default character sets used by the two operating systems. To ensure proper handling of filenames across platforms, follow these steps:
Use UTF-8 Character Encoding:
Ensure that your PHP scripts are using UTF-8 character encoding. This will allow PHP to handle filenames with international characters properly.To set the default character encoding to UTF-8 in PHP, add the following line at the beginning of your PHP script:
phpheader('Content-Type: text/html; charset=utf-8');
Configure Samba/CIFS Correctly:
If you are using Samba/CIFS to access files on the Raspberry Pi from Windows 10, make sure that the Samba configuration includes the "utf8" and "iocharset" options.Open the Samba configuration file (usually located at
/etc/samba/smb.conf
) and add the following lines to the[global]
section:javaunix charset = UTF-8
dos charset = CP850
iocharset = utf8
Save the file and restart the Samba service to apply the changes:
bashsudo service smbd restart
The "dos charset" option sets the character set used by Windows clients to CP850, which is a character set that includes many special characters commonly used in Western European languages. The "iocharset" option sets the character set used for filenames between the Windows and Linux systems to UTF-8.
Use mbstring Extension in PHP:
The PHPmbstring
extension provides multibyte character string functions that are useful for working with Unicode characters. Make sure thembstring
extension is enabled in your PHP configuration. You can check if it's enabled by runningphpinfo()
and searching for "mbstring" in the output.If it's not enabled, you can enable it by uncommenting or adding the following line in your
php.ini
file:makefileextension=mbstring
After making changes to the PHP configuration, don't forget to restart the web server to apply the changes.
With these steps, you should be able to handle filenames with international characters correctly between your Raspberry Pi and Windows 10 using PHP. However, it's essential to ensure that the filenames are stored and transmitted using UTF-8 encoding consistently throughout your application and file system.
