Hi there, im trying to figure out what types of security is needed / or can be applied in a Flash\>php\> MySQL project. Could you guys help me out with this, im kinda confused. Here’s what im dealing with:

**MD5** found an encryption .AS and it seems to work, but PHP has this built in, my question;Which should i use, PHP or Flash version, and why?

\*\*regular expressions \*\*not sure if this is the term, but what i mean is that you dont allow certain characters like \*" ’ \< \> $ \*etc when storing in database. How could you best protect against this, via flash or php?  
And what characters could cause problems.  
(i can imagine if someone knows what php-file is used, and the security is all in flash you still have a problem)

What other types of securtiy could you recommend?

:cap: hope somebody can help me with this, Thanks
