How to implement
"Idiotic" => "inclusighted ",
"Moronic" => "unreasonable ",
"Insane" => "illogical"

------ Solution --------------------
Foreach ($ badwords as $ key => $ value ){
If (strpos ($ text, $ key )! = False)
Return str_replace ($ key, $ value, $ text );
}
========================

Change
Return strtr ($ text, $ badwords );
