An array2xml function that works!

[marcuscarver]

For those that might need this function, and have crawled through the endless "array2xml" or "array to xml" results from google like I have, I've developed a clean and concise function that does the job.

 

/*
* array2xml() will convert any given array into a XML structure.

*
* Arguments :  $array      - The array you wish to convert into a XML structure.
*              $name       - The name you wish to enclose the array in, the 'parent' tag for XML.
*              $standalone - This will add a document header to identify this solely as a XML document.
*              $beginning  - INTERNAL USE... DO NOT USE!
*
* Return:      Gives a string output in a XML structure
*
* Use:         echo array2xml($products,'products');
*              die;
*/

function array2xml($array, $name='array', $standalone=TRUE, $beginning=TRUE) {

  global $nested;

  if ($beginning) {
    if ($standalone) header("content-type:text/xml;charset=utf-8");
    $output .= '<'.'?'.'xml version="1.0" encoding="UTF-8"'.'?'.'>' . LF;
    $output .= '<' . $name . '>' . LF;
    $nested = 0;
  }
  
  // This is required because XML standards do not allow a tag to start with a number or symbol, you can change this value to whatever you like:
  $ArrayNumberPrefix = 'ARRAY_NUMBER_';
  
foreach ($array as $root=>$child) {
    if (is_array($child)) {
      $output .= str_repeat(" ", (2 * $nested)) . '  <' . (is_string($root) ? $root : $ArrayNumberPrefix . $root) . '>' . LF;
      $nested++;
      $output .= array2xml($child,NULL,NULL,FALSE);
      $nested--;
      $output .= str_repeat(" ", (2 * $nested)) . '  </' . (is_string($root) ? $root : $ArrayNumberPrefix . $root) . '>' . LF;
    }
    else {
      $output .= str_repeat(" ", (2 * $nested)) . '  <' . (is_string($root) ? $root : $ArrayNumberPrefix . $root) . '><![CDATA[' . $child . ']]></' . (is_string($root) ? $root : $ArrayNumberPrefix . $root) . '>' . LF;
    }
  }
  
  if ($beginning) $output .= '</' . $name . '>';
  
  return $output;
}

This is a code snippet, what does it have to do with application design?

You also need to define "LF" before function

 

define('LF', "\r\n");
