To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/php/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:
    /usr/local/etc/php/7.4/

To have launchd start php now and restart at login:
  brew services start php
Or, if you don't want/need a background service you can just run:
  php-fpm

提示： 配置Apache的httpd.conf的配置来使用PHP，并重启Apache：
在加载模块中加入

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

php.ini 和 php-fpm.ini文件在

 /usr/local/etc/php/7.4/

不使用服务器，可以运行php-fpm来解析PHP文件

启动php

$ sudo php-fpm 

结束php进程

$ sudo pkill php-fpm

如果还没有安装 Composer，在 Linux 和 Mac OS X 中可以运行如下命令：
下载

curl -sS https://getcomposer.org/installer | php

添加到/usr/local/bin中

mv composer.phar /usr/local/bin/composer
