pecl path:

/opt/homebrew/Cellar/[email protected]/7.4.32/bin/pecl

pecl extension directory:
执行 pecl config-get ext_dir

/opt/homebrew/lib/php/pecl/20190902

这里需要先确认该目录是否存在，如果不存在会导致 Xdebug 安装失败，就需要手动创建。执行 mkdir -p /opt/homebrew/lib/php/pecl/20190902 即可。

最后执行 pecl install xdebug 即可完成安装。该命令会把 xdebug.so 安装到目录 /opt/homebrew/lib/php/pecl/20190902 中。并且会在 php.ini 文件的顶部添加zend_extension="xdebug.so" 。

执行 php -v 检查是否安装成功
