The error indicates a mismatch between the PHP API version of the sodium extension and the version of PHP installed in your XAMPP environment. Specifically:
- The
sodium module is compiled with API=20190902 (PHP 7.4.x).
- Your XAMPP installation uses
API=20220829 (PHP 8.2.x).
To resolve this, you need to ensure that the sodium.so file matches the PHP version installed in XAMPP. Here’s how to fix it:
1. Remove the Incompatible sodium.so
Navigate to the XAMPP extensions directory:
cd /opt/lampp/lib/php/extensions/no-debug-non-zts-20220829/
Remove or rename the existing sodium.so:
mv sodium.so sodium.so.bak
2. Recompile the Sodium Extension for PHP 8.2.x
Step 1: Install Required Dependencies
Ensure that the necessary development tools and libraries are installed:
sudo apt-get update
sudo apt-get install -y build-essential autoconf libtool libsodium-dev php-dev
Step 2: Download PHP Source Code
Download the exact PHP version source code (8.2.4 in your case):
wget https://www.php.net/distributions/php-8.2.4.tar.gz
tar -xvzf php-8.2.4.tar.gz
cd php-8.2.4/ext/sodium
Step 3: Compile the Sodium Extension
Run the following commands to compile the Sodium extension:
/opt/lampp/bin/phpize
./configure --with-php-config=/opt/lampp/bin/php-config
make
sudo make install
Step 4: Verify Compilation
After compilation, the sodium.so file will be installed in the correct XAMPP extension directory, typically /opt/lampp/lib/php/extensions/no-debug-non-zts-20220829/.
3. Enable the Sodium Extension in XAMPP
Open the XAMPP php.ini file:
sudo nano /opt/lampp/etc/php.ini
Add the following line if it’s not already present:
extension=sodium
Save and close the file (Ctrl + O, Enter, Ctrl + X).
4. Restart XAMPP
Restart XAMPP to load the newly compiled extension:
sudo /opt/lampp/lampp restart
5. Verify the Sodium Extension
Check if the Sodium extension is loaded:
/opt/lampp/bin/php -m | grep sodium
Verify using phpinfo():
6. Troubleshooting
Error: Still Mismatched API Versions:
Ensure that you are compiling the Sodium extension with the same PHP version as XAMPP. Verify the XAMPP PHP version with:
/opt/lampp/bin/php -v
Missing Compilation Tools:
If phpize or other tools are missing, install them:
sudo apt-get install php-dev
This process ensures that the sodium.so extension matches your XAMPP's PHP version and resolves the error. Let me know if you encounter any issues!
