Extracting last two characters from a numeric string

Question

Okay. Say I have string

'193'

And I want to remove the last numbers and store them in an array so I can do operations with them. I know substr can delete the 2 characters, but I'm not sure how to store them after they've been removed..

Answer 1

$end[] = substr("193", -2);

Will store "93" in the array $end

Answer 2

Why not treat it as a number (your question said it's a numeric string) ?

$last2 = $str%100;
