PHP Moon Phase icon generator

Post by mcrossley »

I wanted a simple 'clean' looking Moon phase icon for my home, so I took the code to be found on the PHP online manual for imagefilledellipse() and cleaned it up a bit, this just uses a mean lunar period, and linear interpolation to get this....
<Sorry, this script has been deleted>

Not very accurate, so I changed to to use a sin() interpolation to allow for a spherical moon and got this...
Image
Much better, and actually pretty accurate (for this lunation anyway).

Then I used one the 'many' PHP Moon Phase classes for a pretty accurate geocentric solution, and got this...
Image
Very subtly different from the second one, and probably not worth the extra computation.

Veiw the source of any of them with ?view=src
They default to 75x75 pixels with no parameters, and you can provide a transparent=false parameter to get a black background.

Feel free to use the code, I basically got it for free!
