What are the limitations of using PHP for server administration tasks and when should other tools be considered?

When using PHP for server administration tasks, it is important to note that PHP may not have all the necessary functionalities and permissions required for certain tasks. In such cases, it is advisable to use other tools or languages that are specifically designed for server administration, such as Bash or Python.

// Example of checking server status using PHP
$output = shell_exec('uptime');
echo $output;
