PHP Custom Application

:::note The Dagger PHP SDK requires PHP 8.2 or later. :::

Install the Dagger PHP SDK in your project using composer:

composer require dagger/dagger

This example demonstrates how to test a PHP application against multiple PHP versions using the PHP SDK.

Clone an example project:

git clone https://github.com/slimphp/Slim-Skeleton.git
cd Slim-Skeleton

Create a new file named test.php in the project directory and add the following code to it.

This PHP program imports the Dagger SDK and defines a function named test(). This test() function creates a Dagger client, which provides an interface to the Dagger API. It also defines the test matrix, consisting of PHP versions 8.2 to 8.4 and iterates over this matrix, downloading a PHP container image for each specified version and testing the source application in that version.

Run the PHP program by executing the command below from the project directory:

dagger run php test.php

The dagger run command executes the specified command in a Dagger session and displays live progress. The program tests the application against each version concurrently and displays the following final output:
