Mixed Characters - Help?

[PierceCoding]

Hi there, I've been searching for hours on how to properly do this. No luck so far!

 

Anyways, I do not want to limit things to being only caps or only lowercase. I also do not want to write out every single possible word for filtering.

Example:

$word = "Swear Word";

if(strstr($paragraph,$word)) {

die($die_error);

}

 

I don't want to have to type this out 50 different ways like:

SWEAR WORD

SwEaR WoRd

SWeaR WORd

etc..

 

I am unable to find a function where it will understand the word whether it is mixed, fully caps, or lowercase.

 

 

I'm sure they have this for badword filters as people could just bypass the badword filter by typing a swear in via mixed case like "SwEaR WoRDs".

 

 

Any help is appreciated

well convert the user input to lowercase and check it against your list.

forexample

 

you have "swear word" in your list,

 

$userword=strtolower($_GET["user_word"]);

and check this $userword against your list

hope you understood what i meant

Hey thanks for your help, I actually just found it. The function I was using was case-sensitive 

stristr() works for what I want it to do.
