Are there specific PHP libraries or extensions that can be used for secure shell command execution instead of shell_exec?

When executing shell commands in PHP, it is important to prioritize security to prevent potential vulnerabilities. Instead of using shell_exec, which can pose security risks, it is recommended to use specific PHP libraries or extensions that are designed for secure shell command execution. One popular option is the "ssh2" extension, which provides functions for secure shell connections and command execution. 

// Example of using the ssh2 extension for secure shell command execution
$connection = ssh2_connect('example.com', 22);
ssh2_auth_password($connection, 'username', 'password');

$stream = ssh2_exec($connection, 'ls -l');
stream_set_blocking($stream, true);
$data = '';
while ($buffer = fread($stream, 4096)) {
    $data .= $buffer;
}

fclose($stream);
echo $data;
