web server打开后，在打开localhost 成功！

2. PHPBrew(PHP版本管理)

官方文档 https://github.com/phpbrew/phpbrew/blob/master/README.cn.md
HomeBrew关于 PHPBrew的文档 https://formulae.brew.sh/formula/phpbrew

安装
这里我们通过homebrew安装

brew install phpbrew

init

Using root: /Users/fanzhen/.phpbrew
Initialization successfully finished!
<=====================================================>
Phpbrew environment is initialized, required directories are created under

    /Users/fanzhen/.phpbrew

Paste the following line(s) to the end of your ~/.bashrc and start a
new shell, phpbrew should be up and fully functional from there:

    source /Users/fanzhen/.phpbrew/bashrc

To enable PHP version info in your shell prompt, please set PHPBREW_SET_PROMPT=1
in your `~/.bashrc` before you source `~/.phpbrew/bashrc`

    export PHPBREW_SET_PROMPT=1

To enable .phpbrewrc file searching, please export the following variable:

    export PHPBREW_RC_ENABLE=1


For further instructions, simply run `phpbrew` to see the help message.

Enjoy phpbrew at $HOME!!

<=====================================================>

# phpbrew
source /Users/fanzhen/.phpbrew/bashrc
export PHPBREW_SET_PROMPT=1
export PHPBREW_RC_ENABLE=1

之后就可以正常使用了

安装php7.4.33版本

phpbrew install 7.4.33 +default

但是这里下载的速度太慢了需要解决！！！

3. 直接使用homebrew 安装php环境

1、查看 php 版本

php -v

此时发现没有php环境的话，就全新安装

2、brew tap加速，使用github库
homebrew默认使用官方的库，但这个源很慢，一般我们会使用第三方tap

brew tap shivammathur/php

3、安装php7.4

brew install shivammathur/php/php@7.4

4、创建link，这样可以在全局环境里访问

brew link --overwrite --force php@74

==> Summary
🍺  /opt/homebrew/Cellar/php@7.4/7.4.33_5: 499 files, 72.9MB
==> Running `brew cleanup php@7.4`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
==> Caveats
==> php@7.4
To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /opt/homebrew/opt/php@7.4/lib/httpd/modules/libphp7.so

    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html

The php.ini and php-fpm.ini file can be found in:
    /opt/homebrew/etc/php/7.4/

php@7.4 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.

If you need to have php@7.4 first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/php@7.4/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/opt/homebrew/opt/php@7.4/sbin:$PATH"' >> ~/.zshrc

For compilers to find php@7.4 you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/php@7.4/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/php@7.4/include"

To start shivammathur/php/php@7.4 now and restart at login:
  brew services start shivammathur/php/php@7.4
Or, if you don't want/need a background service you can just run:
  /opt/homebrew/opt/php@7.4/sbin/php-fpm --nodaemonize

# php7.4
export PATH="/opt/homebrew/opt/php@7.4/bin:$PATH"
export PATH="/opt/homebrew/opt/php@7.4/sbin:$PATH"
export LDFLAGS="-L/opt/homebrew/opt/php@7.4/lib"
export CPPFLAGS="-I/opt/homebrew/opt/php@7.4/include"
