it really depends how you have initially installed PHP 5. did you installed and working with IIS or you are using a WAMP server. If it is a test system I suggest to reinstall everything for faster results. contact me privately if you want a low cost production dolibarr SAAS solution ---

1. May be not too fast! Note that **PHP 7.1** comes with some backward incompatibility changes, so make sure to check everything and have backups. … 2. Add ondrej/ **php** PPA. Ubuntu. … 3. List your current **PHP** packages. … 4. **Install PHP 7.1**. … 5. Test if **PHP** version is indeed **7.1**. … 6. Remove old 7.0 packages. Have you tried doing this?
