Hi, After doing a long search on stackoverflow i didn't find any one talked about this even if it's a big choice, the Question is what's the best in order to prevent both of XSS and SQL injection, Escaping the data then store it in the DB or Store it as it is and escape when output it?

Note: it is better if you give some examples of practics if possible.

Thanks
