How to enable PHP redis extension on Travis

Question

I'm running Travis CI for running my tests. I'm using the Trusty container with php v5.6.

Here is my entire .travis.yml file:

language: php

dist: trusty

php:
  - '5.4'

before_script:
  - phpenv config-rm xdebug.ini
  - before_script: echo "extension = redis.so" >> ~/.phpenv/versions/$(phpenv version-name)/etc/php.ini

sudo: required

install:
  - npm install -g gulp
  - composer install

env:
  - APP_ENV=circleci

script:
  - gulp test

The before_script: syntax is copied directly from the travis documentation but my builds fail with a composer error saying:

- The requested PHP extension ext-redis * is missing from your system. Install or enable PHP's redis extension.

It appears that this documentation is incorrect! Instead of before_script: it needs to be before_install:. This seems to work fine:

before_install:
  - phpenv config-rm xdebug.ini
  - before_script: echo "extension = redis.so" >> ~/.phpenv/versions/$(phpenv version-name)/etc/php.ini
