I haven't studied the details of this implementation, but they generally work something like this.
(Apache is only being used as an example, this could be a different web server, the details would change, but the principle remains the same) In normal use Apache has a module that detects the .php extension and passes execution to the php interpreter. With a scheme like this Apache would pass control to compiled version of the page instead. This could be global (for all .php on the machine) or could be managed through mod rewrite or similar. Depending on the implementation, the compiled version could be an Apache module loaded with Apache or could be an external executable that Apache launches on demand.

I'm not entirely proud of fighting vague and irrational fear of the unknown by invoking vague and irrational fear of the unknown, but I think it did make an impression.
