PHP

Versions

We use PHPENV to manage PHP versions. We currently have 5.3, 5.4, 5.5, 5.6, 7.0 and 7.1 installed. These are aliases that are pointing to the specific 5.x.x and 7.x.x versions we have installed.

For a full list of installed versions (including patch level versions) open a SSH debug build and run the following command

phpenv versions

Ubuntu 14.04

By default we use 5.5

Specific versions: 5.3.29, 5.4.45, 5.5.38, 5.6.29, 7.0.14 and 7.1.0

Do not rely on the specific versions we have as this can change any time and could break your build.

You can change the version you want to use by running phpenv local PHP_VERSION in your setup commands. For example

phpenv local 5.5

PHP.ini

You can access and change the php.ini file in

/home/rof/.phpenv/versions/$(phpenv version-name)/etc/php.ini

Dependencies and Extensions

You can install dependencies through pear and composer. Extensions can be installed through pecl. If you need any other tools please send us a message.

xdebug

By default xdebug is installed and enabled on the build VMs. If you want to remove it, add the following command to your builds.

rm -f /home/rof/.phpenv/versions/$(phpenv version-name)/etc/conf.d/xdebug.ini

Pear

pear install pear/PHP_CodeSniffer

Composer

composer install --no-interaction

Cache

If you want cache composer dependencies during builds, please add the following environment variable to your build configuration.

COMPOSER_HOME=${HOME}/cache/composer

To make sure that the dependency cache is used by all of your dependencies, please call composer via the following snippet.

composer install --prefer-dist  --no-interaction

GitHub API

To speed up Composer you can install packages from dist by replacing --prefer-source with --prefer-dist. However as GitHub’s API is rate limited, you then might see errors similar to this:

- Installing phpunit/phpunit (3.7.37)
Downloading: connection... Failed to download phpunit/phpunit from dist: Could not authenticate against github.com`
Now trying to download from source

To avoid this create a new personal access token on GitHub. For the description you can use something like Codeship Composer and you can unselect all scopes. Copy your personal access token and add it to the environment variables in your Codeship project settings (on the Environment page) as GITHUB_ACCESS_TOKEN.

Then use the following Setup Commands in your Codeship project settings:

composer config -g github-oauth.github.com $GITHUB_ACCESS_TOKEN
composer install --prefer-dist --no-interaction

PHPUnit

As we already have a version of PHPUnit preinstalled on our build VMs, you need to remove this version first, before upgrading to a different version via Composer.

composer global remove "phpunit/phpunit" --update-with-dependencies
composer global require "phpunit/phpunit=5.*"

Pecl

pecl install -f memcache

phpenv rehashing

If you install a new executable through a pear package make sure to run

phpenv rehash

so phpenv is aware of the new executable and sets it up correctly

Running your PHP Server

If you want to test against a running PHP Server you can use the builtin one to start a server in the current directory. It will serve files from this directory.

nohup bash -c "php -S 127.0.0.1:8000 2>&1 &" && sleep 1; cat nohup.out

You can access it in your tests on 127.0.0.1:8000.

Also take a look at the PHP built-in webserver docs in the PHP documentation
