Is there an easy way to downgrade or switch php versions?

Open Litwilly opened this issue 4 years ago • 8 comments

Installed LAMP with php 8, having some issues so until I can resolve would like to downgrade to php 7.

Rename PHP Install location /usr/local/php and reinstall it with same option.

mv /usr/local/php /usr/local/php8

and

./lamp.sh

Select PHP 7.

If /usr/local/apache and /usr/local/mysql already exists, it will be skip the installation when reinstall LAMP.

The new system is not compatible with the old software.

@ducna96 No, you still need to chosen install Apache and MySQL. and other options need to chosen too. If path /usr/local/apache and /usr/local/mysql already exists, there will be skip the installation when reinstall LAMP.
