Question

I have to compare two strings such as INTU and IXTE and check if two or more of the characters are the same. With the previous two strings, I’d want to return true, since the I and the T are the same.

Order of letters in the string ends up being irrelevant as each character can not appear in different positions in the string. It seems like there should be an easy way to do this.

Answer 1

look at similar_text(). The following code is untested but i think it would work as you want.

$a = "INTU";
$b = "IXTE";

$is_match = ( similar_text($a , $b) >= 2) ;
