1. Have a directory for the user for shell scripts:

mkdir ~/bin

2. Have this directory in the shell's PATH. Edit

~/.bash_profile

3. and add:

[ -d ~/bin ] && { PATH="${HOME}/bin:${PATH}"; }
export PATH

4. Then manually symlink the correct php into ~/bin/php. Or you can put the following script into

~/bin/usephp
#!/bin/sh
[ "$#" -lt "1" ] && {
  echo "Configure current shell to use a specific major PHP version.

    Usage: usephp 7"
  exit 0
}
binary="php${1}"
wanted="/usr/bin/${binary}"
[ ! -f "${wanted}" ] && {
  echo "'${binary}' not found. Using 'php'."
  wanted="/usr/bin/php"
}
ln -sf "${wanted}" "${HOME}/bin/php"
inUse=$(php -nr "echo phpversion();")
echo "Shell configured to use PHP ${inUse}."

5. Make it executable

chmod u+x ~/bin/usephp

6. and use it like so: use php version 8

usephp 8

Output:

php -v
PHP 8.0.2 (cli) (built: Feb  2 2021 18:26:02) ( NTS )

use php version 7

usephp 7

Output:

php -v
PHP 7.4.15 (cli) (built: Feb  2 2021 18:30:22) ( NTS )
