Detect continuous integration environment and get information of current build
License: MIT License
Languages: PHP
PHP library to detect continuous integration environment and to read information of the current build.
This library is useful if you need to detect whether some CLI script/tool is running in an automated environment (on a CI server). Based on that, your script may behave differently (for example hide some information which relevant only for a real person - like status bar, etc.).
Plus, you may want to detect some information about the current build: build ID, git commit, branch etc. For example, if you'd like to record these values to log, publish them to Slack, etc.
The detection is based on environment variables injected to the build environment by each CI server. However, these variables are named differently in each CI. This library contains adapters for many supported CI servers to handle these differences, so you can make your scripts (and especially CLI tools) portable to multiple build environments.
These CI servers are currently recognized:
If your favorite CI server is missing, feel free to send a pull-request!
Install using Composer:
$ composer require ondram/ci-detector
<?php
$ciDetector = new \OndraM\CiDetector\CiDetector();
if ($ciDetector->isCiDetected()) { // Make sure we are on CI environment
echo 'You are running this script on CI server!';
$ci = $ciDetector->detect(); // Returns class implementing CiInterface or throws CiNotDetectedException
// Example output when run inside GitHub Actions build:
echo $ci->getCiName(); // "GitHub Actions"
echo $ci->getBuildNumber(); // "33"
echo $ci->getBranch(); // "feature/foo-bar" or empty string if not detected
// Conditional code for pull request:
if ($ci->isPullRequest()->yes()) {
echo 'This is pull request. The target branch is: ';
echo $ci->getTargetBranch(); // "main"
}
// Conditional code for specific CI server:
if ($ci->getCiName() === OndraM\CiDetector\CiDetector::CI_GITHUB_ACTIONS) {
echo 'This is being built on GitHub Actions';
}
// Describe all detected values in human-readable form:
print_r($ci->describe());
// Array
// (
// [ci-name] => GitHub Actions
// [build-number] => 33
// [build-url] => https://github.com/OndraM/ci-detector/commit/abcd/checks
// [commit] => fad3f7bdbf3515d1e9285b8aa80feeff74507bde
// [branch] => feature/foo-bar
// [target-branch] => main
// [repository-name] => OndraM/ci-detector
// [repository-url] => https://github.com/OndraM/ci-detector
// [is-pull-request] => Yes
// )
} else {
echo 'This script is not run on CI server';
}
Available methods of CiInterface
instance (returned from $ciDetector->detect()
):
Method | Example value | Description |
---|---|---|
getCiName() |
GitHub Actions |
Name of the CI server. The value is one of CiDetector::CI_* constants. |
getBuildNumber() |
33 |
Get number of this concrete build. Build number is usually human-readable increasing number sequence. It should increase each time this particular job was run on the CI server. Most CIs use simple numbering sequence like: 1, 2, 3... However, some CIs do not provide this simple human-readable value and rather use for example alphanumeric hash. |
getBuildUrl() |
https://github.com/OndraM/ci-detector/commit/abcd/checks or empty string |
Get URL where this build can be found and viewed or empty string if it cannot be determined. |
getCommit() |
b9173d94(...) |
Get hash of the git (or other VCS) commit being built. |
getBranch() |
my-feature or empty string |
Get name of the git (or other VCS) branch which is being built or empty string if it cannot be determined. Use getTargetBranch() to get name of the branch where this branch is targeted. |
getTargetBranch() |
main or empty string |
Get name of the target branch of a pull request or empty string if it cannot be determined. This is the base branch to which the pull request is targeted. |
getRepositoryName() |
OndraM/ci-detector or empty string |
Get name of the git (or other VCS) repository which is being built or empty string if it cannot be determined. This is usually in form "user/repository", for example OndraM/ci-detector . |
getRepositoryUrl() |
https://github.com/OndraM/ci-detector or empty string |
Get URL where the repository which is being built can be found or empty string if it cannot be determined. This is either HTTP URL like https://github.com/OndraM/ci-detector but may be a git ssh url like ssh://[email protected]/OndraM/ci-detector |
isPullRequest() |
TrinaryLogic instance |
Detect whether current build is from a pull/merge request. Returned TrinaryLogic object's value will be true if the current build is from a pull/merge request, false if it not, and maybe if we can't determine it (see below for what CI supports PR detection).Use condition like if ($ci->isPullRequest()->yes()) { /*...*/ } to use the value. |
describe() |
[...] (array of values) |
Return key-value map of all detected properties in human-readable form. |
Most CI servers support (✔) detection of all information. However some don't expose necessary environment variables, thus reading some information may be unsupported (❌).

Check codestyle, static analysis and run unit-tests:
composer all
To automatically fix codestyle violations run:
composer fix
