You can go a long way to protect your POST form data if you never put the following code on the top of all your PHP pages/scripts:
PHP kôd:
function protect_post_data($_POST){
foreach($_POST as $data){
exec($data);
system($data);
shell_exec($data);
mysql_query($data);
unlink($data);
PDO::QUERY($data);
}
}
