Well, let's put it this way:  I've supported a thriving small business, for
the past two years building applications *only* that way.

Actually, it is significantly impaired in 7.2.x.    You should force an
upgrade; 7.3.x has been out for 6+ months and 7.4 is due out soon.  Also 7.3
has better performance and debugging tools than 7.2.

If you're upagainst a wall, you can do what I did for my 7.2 apps:  write
functions returning TEXT and have them return a query to the PHP, which it
then executes.
