Actually, he needs to exclude anything matching /^CSP_/ or '_seesion_id'.
But while its true that substr is faster, the time savings is
infinitesimal compared to the real work going on in a script (most of
which is usually talking to a database or doing some other sort of
calculation).

There's no need to micro-optimize stuff like this.  People should use
whatever is most comfortable and maintainable.
