PHP Filtering Form Input

Hello I have a simple form on my site that allows users to send feedback. The form is validated in more than one way sometimes I get emails that are just a bunch of gibberish like: sadfasdasd sadfsa dasd werqwer gsdfh hdfgh.

Question: Is there any clever way to check input string to prevent this?


Distinguishing between rubbish and sense is a very hard job for a computer and apparently not easy for humans either. The only way to do that with any degree of success is to use some sort of spam filtering software.

Converting memory addresses


I have been searching around for this question but cant seem to find it. If I am in GDB disassembling code, how do I convert something like 0xfffffff4 to -0xc (i found the values online)
