    $ brew upgrade php : ( get the latest homebrew php packages )

    $ brew install [email protected] : ( Install php 7.4 )

    $ brew link [email protected] : ( create an alias to this keg-only version; see comments output during installation )

    $ echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile : ( Add the alias to your path; see comments output during installation )

    $ source ~/.bash_profile : ( Reload .bash_profile to use the new settings immediately )

    I am not sure about the 10.13.6 High Sierra version, but this worked for me.

    1. php -v (To see what version php has. But you have already done that)

    2. brew unlink php55 (In my case I use php 5.5)

    3. brew install php73 (For the php 7.3 version.)

    4. php -v (To check of the version is the one I need.)

    Hope this helps.

    First:

    ~ brew update

    then install the latest php version (PHP 8.0.8 in the time of writing):

    ~ brew install php

    link new version to /usr/local/Cellar/php/8.0.8:

    ~ brew link php

    then open the shell’s resource file, located in ~/ (in my case Z-shell or ZSH):

    ~ sudo vi .zshrc

    press i to insert and somewhere in your resource file append a new path to your $PATH variable, like this:

    export PATH=$PATH:/usr/local/opt/[email protected]/bin

    or in the case of ZSH, you should also be able to do it like this:

    path+=('/usr/local/opt/[email protected]/bin')
export PATH

    then press esc to escape from insert mode, and press :wq to save/write and quit the editor. The final step is to source the file to apply new changes permanently.

    ~ source .zshrc

    Try new PHP version:

    ~ php -v

    I solved the problem maintaining homebrew for both of the arch (arm64 and x86_64).
    In that case I choose Homebrew location dynamically depending on the terminal arch in my .bashrc.

    if [[ $(uname -m) == "x86_64" ]]; then
  echo "x86_64 detected" 
  export PATH=/usr/local/Homebrew/bin:$PATH
else
  echo "arm64 detected"
  export PATH=/opt/homebrew/bin:$PATH
fi

    And installed tmux in both of the terminal (native and rosetta) and after reload it works correctly. Full .zshrc can be found here.
