ASCII Export button

[nine_D]

I want a button that takes a data set from a mysql table, converts it to ascii, and saves it on the user's computer. Does anyone know a function or how to do this using php or javascript? I cannot find any info on how to do this so your comments would be appreciated. Thanks.

what format is the data in before conversion? Unicode-8? Binary? Hex?

Not sure. Some will be integers but most will be text.
