Convert Array to XML object.

[ryancanulla]

Hi there,

How would I convert an array to XML? I am using PHP to provide the files in a directory as an array. I will then take this info and use it as XML in flex to display all files within a specific directory.

I want to call this file as an HTTPRequest and return the XML. Thanks!

<?php
$dir    = 'test';
$files = scandir($dir);
$files2 = scandir($dir, 1);

print_r($files);
return("this is a test");

//print_r($files2);
?>

Well, assuming that you can get the array into this type of array, it would be simple:

Array (
  [dirname] => Array (
      'Filename 1',
      'Filename 2'
  ),
  [dirname] => Array (
      'Filename 3',
      'Filename 4'
  ),
  [0] => 'Filename',
  [1] => 'Filename 2',
  [2] => 'Filename 3'
)

You could then do something like this:

<?php

function generateDirectoryXML($directory, $filelist)
{
    $xml = '<'.$directory.' name="'.$directory.'">';
    foreach($filelist as $dir => $file)
    {
        // We are dealing with a directory and it's children
        if(is_array($file) && is_string($dir))
        {
            $xml .= generateDirectoryXML($dir, $file);
        }
        else
        {
            $xml .= '<file>'.$file.'</file>';
        }
    }
    $xml .= '</directory>';

return $xml;
}

// Assuming the above array is stored in "$filelist" ....
$xml = '<?xml version="1.0" encoding="utf-8"?>
<directoryListing>';
foreach($filelist as $dirname => $file)
{
    $xml .= generateDirectoryXML($dirname, $file);
}
$xml .= '</directoryListing>';

echo $xml;

Hope that helps. It's not guaranteed to work 100%; however, it should push in the right direction.
