# 切换版本
alias use-php53='unlink-php; brew link --overwrite --force php@5.3 && php -v'
alias use-php54='unlink-php; brew link --overwrite --force php@5.4 && php -v'
alias use-php55='unlink-php; brew link --overwrite --force php@5.5 && php -v'
alias use-php56='unlink-php; brew link --overwrite --force php@5.6 && php -v'
alias use-php70='unlink-php; brew link --overwrite --force php@7.0 && php -v'
alias use-php71='unlink-php; brew link --overwrite --force php@7.1 && php -v'

alias use-php74='unlink-php; brew link --overwrite --force php@7.4 && php -v'
alias use-php80='unlink-php; brew link --overwrite --force php && php -v'

后面可以通过 use-php[version] 随意切换版本，或者直接用 php[version] 执行。
