Are there any specific permissions or user rights that need to be granted for PHP to access and retrieve network usage data using system commands?

To access and retrieve network usage data using system commands in PHP, the PHP script must have the necessary permissions to execute the system commands. This typically involves granting the appropriate user rights to the PHP process to run the specific system commands for retrieving network usage data.

<?php
// Execute system command to retrieve network usage data
$network_data = shell_exec('netstat -e');

// Output the network data
echo $network_data;
?>
