  To enable extensions, verify that they are enabled in your .ini files:
    - /Users/yunseok/.phpbrew/php/php-7.3.0/etc/php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

만약 설치 중 dnldhk 같은 에러가 발생한 경우 php extension iconv가 설치되어 있지 않아 생기는 문제입니다. 이를 확인하기 위해서는 php -m으로 설치된 모듈들을 확인할 수 있습니다. 없다면 설치를 해야합니다.
phpbrew를 사용하고 있을 경우 다음과 같이 설치합니다.

phpbrew ext install iconv

만약 설치 중 다음과 같은 에러가 발생한다면 build.log에서 에러를 확인합니다.

Error: Command failed: ./configure --with-php-config=/Users/yunseok/.phpbrew/php/php-7.3.0/bin/php-config >> /Users/yunseok/.phpbrew/build/php-7.3.0/ext/iconv/build.log 2>&1 returns:

# in build.log
configure: error: Please specify the install prefix of iconv with --with-iconv=<DIR>

에러를 확인했는데 위와 같다면 iconv를 빌드하여 경로를 지정해주어야 합니다.

phpbrew ext install iconv --with-iconv=<DIR>

<DIR>은 iconv를 다운받아 빌드한 경로를 입력해줘야합니다.
https://www.gnu.org/software/libiconv/#downloading에서 iconv를 다운받은 후 압축을 풀고 그 폴더에서 다음과 같이 실행합니다.

./configure --prefix=/usr/local
make
make install

위의 명령어를 다 실행한 후 해당 경로를 아래 <DIR>에 입력해주면 설치가 진행됩니다.

phpbrew ext install iconv --with-iconv=<DIR>

그리고 다시 phpstan설치를 진행하면 됩니다.
