First, open the system profile file for editing: cd /etc && vim /etc/profile Enter insert mode by pressing i, scroll to the bottom of the file, and add the following line to prepend the new PHP binary directory to the PATH: export PATH=/www/server/php/73/bin:$PATH Exit insert mode by pressing Esc, then save and quit with :wq!. Finally, apply the changes to the current session: source /etc/profile After sourcing the profile, the new PHP version becomes active; you can verify it with php -v (the verification step is shown in an accompanying screenshot).
