Mac brew 安裝多版本php，這里我把詳細安裝信息留存備用，信息里面有很多干貨～
? ~brew install homebrew/php/php72
==> Installing php72 from homebrew/php
Error: Cannot install homebrew/php/php72 because conflicting formulae are installed.
php70: because different php versions install the same binaries.
Please `brew unlink php70` before continuing.
Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.

==> Caveats
The php.ini file can be found in:
/usr/local/etc/php/7.2/php.ini
???? Extensions ????
If you are having issues with custom extension compiling, ensure that you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:
PATH="/usr/local/bin:$PATH"
PHP72 Extensions will always be compiled against this PHP. Please install them using --without-homebrew-php to enable compiling against system PHP.
???? PHP CLI ????
If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc, ~/.zshrc, ~/.profile or your shell's equivalent configuration file:
export PATH="$(brew --prefix homebrew/php/php72)/bin:$PATH"
???? FPM ????
To launch php-fpm on startup:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php72/homebrew.mxcl.php72.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php72.plist
The control script is located at /usr/local/opt/php72/sbin/php72-fpm
OS X 10.8 and newer come with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:
PATH="/usr/local/sbin:$PATH"
You may also need to edit the plist to use the correct "UserName".
Please note that the plist was called 'homebrew-php.josegonzalez.php72.plist' in old versions of this formula.
With the release of macOS Sierra the Apache module is now not built by default. If you want to build it on your system you have to install php with the --with-httpd option. See? brew options php72 for more details.
To have launchd start homebrew/php/php72 now and restart at login:
brew services start homebrew/php/php72
