This is my proposal to substitute is_palindrome function from GenePHP. I
have just tried to make it simple.
By using function RevComp_DNA2 it allows searching within sequences with
degenerated nucleotides
Although its length is not odd, a pattern like TATANTATA will be
considered palindromic
Uses function RevComp_DNA2

function DNA_is_palindrome($string){
        if ($string==RevComp_DNA2($string)){
                return TRUE;
                }else{
                return FALSE;
                }
}
