security issues

[dror_israel]

Hi,

When I write a code what do I have to do it has no security problems?

What causes security problems?

How can I take care of a user input: like ' or " or other chars that can cause problems?
(I want to put This chars in the DB without replacing them with some other replacments)

Thanks

Hi,

One thing is:
do not trust user input 🙂

e.g. do not use get/post vars withhin sql statments or file operations. without plausibility checks they could be use to compromise the operation.
