PHP installs the latest extension runkit

I don’t know why PHP officially instructed runkit to not be installed after downloading it from github. Later, I found another one on github:
https://github.com/php/pecl-php-runkit. It seems to be the latest one.
Note that it cannot be downloaded in releases. , otherwise it is not the latest
Need to download the latest git: (otherwise it will not work)

git clone https://github.com/php/pecl-php-runkit.git

cd pecl-php-runkit

phpzie

./configure 
  
make  
  
make install  //即可

The above introduces the installation of the latest extension runkit in PHP, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
