Question

I need help with something i’m working on.
I need my PHP code be able to read an uploaded file “A” and write a whole new file “B” with the very same words from A but in a different order

for example if A is

ABC 54 DOG 90 100
56 11 78 YOU 101
A C F H 99

B should be

DOG ABC 90 100 54
78 56 YOU 101 11
F A H 99 C

(so 3rd-1st-4th-5th-2nd. just an example)

What I had in mind was to do something like fwrite($B,JavascriptFunction($A))
but, once into the js part, I really don’t know how to take the right word and put it into the text variable that javascriptfunction have to return.
I know I have to use a .split(‘\n’) to deal with the different lines, but that’s as far as I’ve figured out so far. I know it is probably a silly question but i’m really new to JS.

Thank you

I dont think you need Javascript to read file, but here it goes:

var fileContent='';
var theLocation='';

function readFileViaApplet(n) {
 document.f1.t1.value='Reading in progress...';
 document.ReadURL.readFile(theLocation);
 setTimeout("showFileContent()",100);
}

function showFileContent() {
 if (document.ReadURL.finished==0) {
  setTimeout("showFileContent()",100);
  return;
 }
 fileContent=document.ReadURL.fileContent;
 alert(fileContent); // do what you want with the content
}

Hope it helps
