How can a PHP script be restricted to only rebooting a server when necessary, and not as a regular function?

To restrict a PHP script to only rebooting a server when necessary, you can implement a condition that checks for a specific trigger or condition before allowing the reboot function to execute. This can be done by setting up a flag or variable that indicates when a reboot is required, and only calling the reboot function if this flag is set.

// Check if reboot is necessary
$reboot_required = true;

// Reboot server if necessary
if($reboot_required){
    // Code to reboot server goes here
    echo "Rebooting server...";
} else {
    echo "No reboot necessary.";
}
