Symfony 4 Component Process pass arguments for command - command-line

Question

Symfony Component Process
/**
* #param array $command The command to run and its arguments listed as separate entries
* #param string|null $cwd The working directory or null to use the working dir of the current PHP process
* #param array|null $env The environment variables or null to use the same environment as the current PHP process
* #param mixed|null $input The input as stream resource, scalar or \Traversable, or null for no input
* #param int|float|null $timeout The timeout in seconds or null to disable
*
* #throws LogicException When proc_open is not installed
*/
public function __construct($command, string $cwd = null, array $env = null, $input = null, ?float $timeout = 60)
{ .. }
I have created a command and I use the component Process in my controller.
When I try to run Process I get a ProcessFailException
The command "app:load-file foo bar foobar" failed
Exit Code: 1(General error)
.. ErrorOutput: The filename, directory name, or volume label syntax is incorrect
use Symfony\Component\Process\Process;
..
public function loadFile(KernelInterface $kernel)
{
$argument1 = 'foo';
$argument2 = 'bar';
$argument3 = 'foobar';
$rootDir = $kernel->getProjectDir();
$process = new Process(array(
$rootDir . '/bin/console app:load-file',
$argument1,
$argument2,
$argument3
));
$process->mustRun();
}
What is the correct syntax to run the command from the controller ?
/* *#param array $command The command to run and its arguments listed as separate entries
public function __construct($command, string $cwd = null, array $env = null, $input = null, ?float $timeout = 60)
{ .. }

Answer 1

$cwd is the second parameter of the constructor.
$argument1 = 'foo';
$argument2 = 'bar';
$argument3 = 'foobar';
$rootDir = $kernel->getProjectDir();
$process = new Process(
"bin/console app:load-file $argument1 $argument2 $argument3",
$rootDir
);
try {
$process->mustRun();
} catch(ProcessFailedException $e) {
echo $e->getMessage();
}

Answer 2

$argument1 = 'foo';
$argument2 = 'bar';
$argument3 = 'foobar';
$rootDir = $kernel->getProjectDir();
$process = new Process(
[
$_SERVER['_'],
'bin/console'
'app:load-file',
$argument1,
$argument2,
$argument3,
],
$rootDir
);
$process->mustRun();
$_SERVER['_'] contains path to PHP interpreter executable. Use it if you have several php versions on the server
