手順

php.iniからXdebugのインストール手順を把握する

下記の記事を参考に、
xdebug.orgでXdebugのインストール手順を把握する

php -i > phpinfo.txt でphp.iniに書かれている内容を書き出し、
その内容をxdebug.orgに転記する。

具体的なインストール手順

1. Download xdebug-3.1.5.tgz
   2.Install the pre-requisites for compiling PHP extensions.
   　On your Mac, we only support installations with 'homebrew',
   and brew install php && brew install autoconf should pull in the right packages.
2. Unpack the downloaded file with tar -xvzf xdebug-3.1.5.tgz
3. Run: cd xdebug-3.1.5
4. Run: phpize (See the FAQ if you don't have phpize).

As part of its output it should show:

Configuring for:
...
Zend Module Api No:      20190902
Zend Extension Api No:   320190902

If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.

1. Run: ./configure
2. Run: make
3. Run: cp modules/xdebug.so /usr/local/lib/php/pecl/20190902
4. Create /usr/local/etc/php/7.4/conf.d/99-xdebug.ini and add the line:
   zend_extension = xdebug
