How can PHP interact with system commands like "ps -A" to gather information on FTP processes?

To gather information on FTP processes using PHP, you can use the `exec()` function to run system commands like "ps -A" and capture the output. This allows you to retrieve a list of all running processes, including FTP processes, and parse the relevant information. 

// Run the system command to get a list of all running processes
$output = shell_exec('ps -A');

// Parse the output to find FTP processes
$ftpProcesses = [];
$lines = explode("\n", $output);
foreach ($lines as $line) {
    if (strpos($line, 'ftp') !== false) {
        $ftpProcesses[] = $line;
    }
}

// Output the list of FTP processes
foreach ($ftpProcesses as $ftpProcess) {
    echo $ftpProcess . "\n";
}
