Is exec as expensive in PHP as it is in most other web programming
frameworks? In general calling exec() in the context of a web server
is a bad idea. It usually leads to both performance and security
problems. Caching the output will reduce the problem a bit, but in
general this seems like a suspicious coding practice.
