Re: is there a number translation function?

[<tg-php@xxxxxxxxxxxxxxxxxxxxxx>]

I couldn't find one out there Linda (and I'm sure I've seen them before) so since I'm stuck at work on a Saturday I thought I'd take a break and see if I could hack this out myself.

Probably a more elegant way to do this, but here's what I came up with.  Feel free to use and modify it at will.

It should be infinitely expandable by adding to the "$places" array. (well, 'infinite' in regards to your system's ability to handle long strings, no long ints or floats are used so that shouldn't limit it).

Let me know if you have any questions or if anyone can improve this (always up for learning new tricks :)

Good luck Linda!

Hi,

Does anyone know of a function for translating a decimal number into an 
English number. In other words, if you pass it 1 it will return 'one', if 
you pass it 127 it will return  'one hundred twenty seven', and etc.

Thanks,
Linda
