mac brew 无法找到php7.2 如何安装php7.2

原因是升级过高版本的brew后已经不支持7.2了，但可以通过第三方工具来安装

php 复制代码

brew tap shivammathur/php
brew install shivammathur/php/php@7.2

标题安装完成后会提示以下信息：

php 复制代码

The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.2/

php@7.2 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have php@7.2 first in your PATH, run:
  echo 'export PATH="/usr/local/opt/php@7.2/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/php@7.2/sbin:$PATH"' >> ~/.zshrc

For compilers to find php@7.2 you may need to set:
  export LDFLAGS="-L/usr/local/opt/php@7.2/lib"
  export CPPFLAGS="-I/usr/local/opt/php@7.2/include"

To start shivammathur/php/php@7.2 now and restart at login:
  brew services start shivammathur/php/php@7.2
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/php@7.2/sbin/php-fpm --nodaemonize
==> openjdk@11
For the system Java wrappers to find this JDK, symlink it with
  sudo ln -sfn /usr/local/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk

openjdk@11 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have openjdk@11 first in your PATH, run:
  echo 'export PATH="/usr/local/opt/openjdk@11/bin:$PATH"' >> ~/.zshrc

For compilers to find openjdk@11 you may need to set:
  export CPPFLAGS="-I/usr/local/opt/openjdk@11/include"
==> scrcpy
At runtime, adb must be accessible from your PATH.

You can install adb from Homebrew Cask:
  brew install --cask android-platform-tools

zsh completions have been installed to:
  /usr/local/share/zsh/site-functions

这里面有几个重要信息：

php 复制代码

// 1. php.ini 路径在
/usr/local/etc/php/7.2/

// 2. 确保已经添加环境变量
echo 'export PATH="/usr/local/opt/php@7.2/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/php@7.2/sbin:$PATH"' >> ~/.zshrc

// 3. 供编译器查找php@7.2需要确保以下设置
export LDFLAGS="-L/usr/local/opt/php@7.2/lib"
export CPPFLAGS="-I/usr/local/opt/php@7.2/include"

// 4. 此时可验证php是否安装成功
$ php -v
