Hi all, I have been reading in almost everywhere that we should not use our own custom login and password validations ( like regex etc.) but instead use the filter_var and filter_input built in functions provided by PHP 5 and above. However even after searching for more than an hour for with different search strings, I have not found even a single example that shows how we may validate for a username/login and password in a login form. Can someone be kind enough to provide a strong secure validations for username and login. Additionally I would also like to clarify if the username and login fields in a Login form be manipulated in any manner to pose a security threat? I mean can a hacker craft a username/login or password in such a manner as to pose an injection or any other threat? Thanks all.
