amphp/process AMPHP is a collection of event-driven libraries for PHP designed with fibers and concurrency in mind. amphp/process provides an asynchronous process dispatcher that works on all major platforms (including Windows). It makes running child processes simple. As Windows pipes are file handles and do not allow non-blocking access, this package makes use of a process wrapper , that provides access to these pipes via sockets. On Unix-like systems it uses the standard pipes, as these can be accessed without blocking there. Concurrency is managed by the Revolt event loop. Installation This package can be installed as a Composer dependency. composer require amphp/process The package requires PHP 8.1 or later. Usage Processes are started with Process::start() : <?php require __DIR__ . " /vendor/autoload.php "; use Amp \ ByteStream ; use Amp \ Process \ Process ; // "echo" is a shell internal command on Windows and doesn't work. $ command = DIRECTORY_SEPARATOR === "\\" ? " cmd /c echo Hello World! " : " echo 'Hello, world!' "; $ process = Process :: start ( $ command ); Amp \async (fn () => Amp \ ByteStream \pipe ( $ process -> getStdout (), ByteStream \getStdout ())); Amp \async (fn () => Amp \ ByteStream \pipe ( $ process -> getStderr (), ByteStream \getStderr ())); $ exitCode = $ process -> join (); echo " Process exited with { $ exitCode } . \n"; Custom Working Directory Processes are started with the working directory of the current process by default. The working directory can be customized to another directory if needed: $ process = Amp \ Process \ Process :: start ( $ command , workingDirectory: '/path/of/your/dreams' ); Custom Environment Variables Processes are started with the environment variables of the current process by default. The environment can be customized by passing an associative array mapping variables names to their values: $ process = Amp \ Process \ Process :: start ( $ command , environment: [ 'PATH' => '/usr/bin/local' ]); Versioning amphp/process follows the semver semantic versioning specification like all other amphp packages.
