This is using the default php on macOS:

⇒  php --version
PHP 5.6.25 (cli) (built: Sep 19 2016 15:45:41)

Take a look at your php.ini, sometimes those functions are disabled.

Tried: brew install homebrew/php/php55-pcntl

But get the following error when trying to run with it:

foo@bar:~/sec/s3-buckets-finder|add-dockerfile
⇒  /usr/local/opt/php55/bin/php ./s3-buckets-bruteforcer.php
PHP Warning:  Module 'pcntl' already loaded in Unknown on line 0

Based on: http://stackoverflow.com/questions/34174511/how-to-install-php-extension-pcntl-on-my-mac-osx/34176698#34176698

Edit: This seems more promising: brew install homebrew/php/php71-pcntl

But then I still get a number of warnings:

⇒  $(brew --prefix homebrew/php/php71)/bin/php ./s3-buckets-bruteforcer.php --bucket ~/Desktop/buckets.txt
PHP Warning:  Module 'pcntl' already loaded in Unknown on line 0

..etc..

Is there a specific php version I should be trying to use this with?

[gwen001]

Sorry but I will not rewrite my script to fit old PHP versions unless it affords a great value. You can alter it by yourself or upgrade your PHP.

[gwen001]

I'm not asking you to rewrite it for an old version. I just want to know which version it's written for, and thus what I should be trying to use. In my edit above, I tried it against 7.1 and am still getting issues.

It's not written for a specific version.
Works perfectly with PHP 5.6.30 and PHP 7.0.15, fresh install, no change in php.ini.

[0xdevalias]

Cool. I will try 7.0.x and see how it goes.

Edit: Yeah, awesome. 7.0.x works perfectly. Thanks!

In case it helps anyone else on OSX: brew install homebrew/php/php70-pcntl

$(brew --prefix homebrew/php/php70)/bin/php ./s3-buckets-bruteforcer.php --bucket ~/Desktop/buckets.txt
