Symfony/Process is a versatile PHP component offering functionalities to execute commands in sub-processes. Whether you need to initiate standalone processes or manage multiple concurrent tasks within your PHP application, the Symfony/Process component can handle it all, providing a seamless API to control the state and output of such processes.
To use the Symfony/Process package in your PHP project, you first need to install it using Composer, which is the standard package manager for PHP. To do this, run the following command in your project directory:
composer require symfony/process
Once installed, you can use the component to execute a command. Here is a simple usage example:
use Symfony\Component\Process\Process;
use Symfony\Component\Process\Exception\ProcessFailedException;
$process = new Process(['ls', '-lsa']);
$process->run();
// executes after the command finishes
if (!$process->isSuccessful()) {
throw new ProcessFailedException($process);
}
echo $process->getOutput();
In this example, the Symfony/Process component is used to execute the UNIX 'ls' command, and then output details are printed. Error handling is performed to throw an exception if the process fails.
You can find the official documentation of the Symfony/Process component at the following link: Symfony/Process Documentation. The documentation provides comprehensive guidance and additional examples of using this component, including advanced usage and troubleshooting tips.
