How can the use of escapeshellcmd and escapeshellarg functions impact passing parameters to a CMD file in PHP?

Using the `escapeshellcmd` and `escapeshellarg` functions in PHP can help prevent command injection vulnerabilities when passing parameters to a CMD file. `escapeshellcmd` escapes any shell metacharacters in a command string, while `escapeshellarg` escapes a single argument to be passed to a shell command. By using these functions, you can ensure that the parameters are properly sanitized before being passed to the CMD file, reducing the risk of malicious commands being executed. 

$cmd = 'your_cmd_file.cmd';
$param1 = 'param1_value';
$param2 = 'param2_value';

$escaped_cmd = escapeshellcmd($cmd);
$escaped_param1 = escapeshellarg($param1);
$escaped_param2 = escapeshellarg($param2);

$full_cmd = $escaped_cmd . ' ' . $escaped_param1 . ' ' . $escaped_param2;

// Execute the command
system($full_cmd);
