Various jobs from Javascript to PHP

General information for the business: analytics
Description of requirements/functionality: Goal 1: Convert current script to PHP enabled so the final script can be run on server-side
Goal 2:
1) The library now has about 100K lines and over 100 categories. The upload and process chunks function needs to be less then 5 seconds each, because it takes too long or freezes. The testing should be done on a selection of 30 tags to process a large text document. Add a load timer.

2) The select menu: Add group categories which is pre-define in source code, so user can select a batch of categories instead of individual category as an additional option. This should appear within the "Process for Analysis Menu" with other tags.

3) See the attach file of sketch of logic :
Create 4 new filters, each has its own
-"Process for Analysis Menu" that links to same library,
- a range selector that allows user to select the processed chunks
> ALL chunks
> Chunk 1, 2 ,3 ....n
> User defined chunk range: 1-5 AND 10-15 AND 17-20 ....n
> NONE (skips filter)

4) Duplicate this filter 4 times & link to a single call function button (the run time should not take longer then 10 seconds) Add a load timer.

5) Each filter to automatically generate a count AND % graph each based on the selection or no selection (4 graphs)

6) Single export button to CSV file of the data above

7) HTML5 enabled so it can be accessed via a website later, can run on Firefox, Chrome and Explorer.
OS requirements: Windows, Mac OS
