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. * * Version: 1.0 * * Created by: Marcus Carver © 2008 * * Email: marcuscarver@gmail.com * * Link: http://marcuscarver.blogspot.com/ * * 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; }
