Right well then the solution I described would work for you.

I am all for killing off PHP code[1] but if you have a lot of code to move
there are fully fledged PHP options.

[1] Currently replacing some PHP code with heavily nested for loops that
takes 30 minutes and many hundreds of megs to run with a couple of SQL
queries that take a couple of seconds in total. Though to be fair to PHP you
could create such a monstrosity in Python just as easily, but Python
programmers as a group appear to far more adept programmers.
