check text contents

[lastuser]

Hello!

I am working with PHP and MySQL forum and it is almost done. But there is a one problem still. I have a form where data comes and now I want to check text contents. I want to know is in text swear words (words like shit,damn...) or other forbidden words. Variable name is $text and I was thinking foreach loop to check the test, but has anyone any good idea how to do that?? This seems to be too hard for me. I would be grateful about help! =)

This sounds like a job for [MAN]eregi()[MAN]

You would need to have a pre-defined list of disallowed words saved in a fashion that eregi() could work with. Maybe in a table, in a file (word1, word2, word3,...). If the list of disalowwed words is short, it wouldn't be a problem to loop through them and check your user input.

Maybe use eregi_replace(), your could repalce the disallowed words with **** or &%%# or whatever you like!

I have been tried that too and the result wasn't that what I want. Does anyone know where I can get "word filter" ready?? There is so many things which have to consider that this really needs brains.. =) But I don't think that this is a mission impossible to you guys!
