php-symfonyHow to use the Process component in PHP Symfony?

The Process component in PHP Symfony is used to execute commands in sub-processes. It provides a simple API to run commands in sub-processes and to manage their input and output.

Example code

use Symfony\Component\Process\Process;

$process = new Process('ls -lsa');
$process->run();

// executes after the command finishes
if ($process->isSuccessful()) {
    echo $process->getOutput();
}

Output example

total 8
drwxr-xr-x  3 user  staff   96  8 Jul 16:17 .
drwxr-xr-x  8 user  staff  256  8 Jul 16:17 ..
-rw-r--r--  1 user  staff    0  8 Jul 16:17 test.txt

Code explanation

1. use Symfony\Component\Process\Process; - This imports the Process class from the Symfony Process component.

2. $process = new Process('ls -lsa'); - This creates a new Process object with the command ls -lsa as an argument.

3. $process->run(); - This runs the command in a sub-process.

4. if ($process->isSuccessful()) { - This checks if the command was executed successfully.

5. echo $process->getOutput(); - This prints the output of the command.
