If you have both versions of PHP installed, you can switch between versions using the linkand unlinkbrewcommands.
如果您安装了两个版本的 PHP，则可以使用link和unlinkbrew命令在版本之间切换。
For example, to switch between PHP 7.4 and PHP 7.3
例如，在 PHP 7.4 和 PHP 7.3 之间切换
brew unlink [email protected]
brew link [email protected]
PS: both versions of PHP have be installed for these commands to work.
PS：为了让这些命令可以工作，已经安装了两个版本的 PHP。

If you install PHP with homebrew, you can switch between versions very easily. Say you want php56to point to Version 5.6.17, you just do:
如果使用homebrew安装 PHP ，则可以非常轻松地在版本之间切换。假设您想php56指向 5.6.17 版，您只需执行以下操作：
brew switch php56 5.6.17

i think unlink & link php versions are not enough because we are often using php with apache(httpd), so need to update httpd.conf after switch php version.
我认为 unlink & link php 版本是不够的，因为我们经常使用 php 和 apache(httpd)，所以需要在切换 php 版本后更新 httpd.conf。
i have write shell script for disable/enable php_moduleautomatically inside httpd.conf, look at line 46 to line 54 https://github.com/dangquangthai/switch-php-version-on-mac-sierra/blob/master/switch-php#L46
我在里面写了php_module自动禁用/启用的 shell 脚本httpd.conf，看看第 46 行到第 54 行https://github.com/dangquangthai/switch-php-version-on-mac-sierra/blob/master/switch-php#L46
Follow my steps:
按照我的步骤：
1) Check installed php versions by brew, for sure everything good
1) 通过 brew 检查已安装的 php 版本，确保一切正常
> brew list | grep php
#output
php56
php56-intl
php56-mcrypt
php71
php71-intl
php71-mcrypt
2) Run script
2）运行脚本
> switch-php 71 # or switch-php 56
#output
PHP version [71] found
Switching from [php56] to [php71] ...
Unlink php56 ... [OK] and Link php71 ... [OK]
Updating Apache2.4 Configuration /usr/local/etc/httpd/httpd.conf ... [OK]
Restarting Apache2.4 ... [OK]
PHP 7.1.11 (cli) (built: Nov 3 2017 08:48:02) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies
3) Finally, when your got above message, check httpd.conf, in my laptop:
3）最后，当您收到上述消息时，请httpd.conf在我的笔记本电脑中检查：
vi /usr/local/etc/httpd/httpd.conf
You can see near by LoadModule lines
你可以看到附近的 LoadModule 线
LoadModule php7_module /usr/local/Cellar/php71/7.1.11_22/libexec/apache2/libphp7.so
#LoadModule php5_module /usr/local/Cellar/php56/5.6.32_8/libexec/apache2/libphp5.so
4) open httpd://localhost/info.php
4）打开httpd://localhost/info.php
