Export Flash Builder As3 arrayCollection as csv in the AC original order.

I have an ArrayCollection that I am trying to save to a folder on a web server to csv.

I don't mind using a combination of AS3 and PHP to accomplish this. I tried first sending the data as XML to a php script (magicparser) and then converting it to CSV but I could not get it to work as the csv was not in the order that it was originally in the ArrayCollection. I would like to know how to get this in it's proper order.

 If the CSV can be generated from Flex then auto uploaded to the server for further processing that would be fine as well.


This is how the CSV file should look
H,TUS test,TUS test,02/8/2012,TUS test,1234567890,555,05/19,Visa,
D,MBE37602SH,MBE37602SH,4,EA,54.41,345678,2/8/2012,,
D,MBE37602SH,MBE37602SH,4,EA,54.41,345678,2/8/2012,,

This is what I get


   ,TUS TEST,05/19,Visa,,TUS TEST,555,1234567890,02/8/2012,H,TUS test
  ,MBE37602SH,2/8/2012,,,MBE37602SH,345678,54.41,4,D,EA
 ,MBE37602SH,2/8/2012,,,MBE37602SH,345678,54.41,4,D,EA

This is the ArrayCollection

private var items:ArrayCollection = new ArrayCollection([
{type:"H", cnum:"TUS TEST", fg:"TUS TEST", qty:"02/8/2012", uom:"TUS test", price:"1234567890", po:"555", ddate:"05/19", efield:"Visa", ffield:""},
{type: "D", cnum:"MBE37602SH", fg:"MBE37602SH", qty:"4", uom:"EA", price:"54.41", po:"345678", ddate:"2/8/2012", efield:"", ffield:""},
{type: "D", cnum:"MBE37602SH", fg:"MBE37602SH", qty:"4", uom:"EA", price:"54.41", po:"345678", ddate:"2/8/2012", efield:"", ffield:""}]);
