Converting to php

[BlogSafe]

Thanks for this great code. You likely saved me a bundle on Swiss Ephemeris. Hope it's still active.

To suit my needs tho, I'm working on porting it over to php. Here's my question.

PHP isn't known for it's floating point precision. I can pretty accurately get it to 10 decimal places, mostly accurate to 14. Will this be sufficient to get reasonably accurate results. I'm not expecting JPL Horizon accuracy.

Thanks.
