Macbook m1 Big Sur 安装php7.1 xdebug 折腾记

想当然的进来就是一行

$sudo pecl install xdebug
pecl/xdebug requires PHP (version >= 7.2.0, version <= 8.0.99), installed version is 7.1.33
No valid packages found
install failed

查阅了一下xdebug的下载页，默认安装的xdebug3已经不支持php7.1了。
php7.1只配安装xdebug2，根据在下载页查到的最后一个支持php7.1的版本是2.9.8

$sudo pecl install xdebug-2.9.8

检查一下是否安装成功
