<?php /** * xml2array() will convert the given XML text to an array in the XML structure. * Link: http://www.bin-co.com/php/scripts/xml2array/ * Arguments : $contents - The XML text * $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value. * $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance. * Return: The parsed XML in an array form. Use print_r() to see the resulting array structure. * Examples: $array = xml2array(file_get_contents('feed.xml')); * $array = xml2array(file_get_contents('feed.xml', 1, 'attribute')); */ function xml2array($contents, $get_attributes = 1, $priority = 'tag') { if (!$contents) return array(); if (!function_exists('xml_parser_create')) { // print "'xml_parser_create()' function not found!"; return array(); } // Get the XML parser of PHP - PHP must have this module for the parser to work $parser = xml_parser_create(''); xml_parser_set_option($parser, XML_OPTION_TARGET_ENCODING, "UTF-8"); // http://minutillo.com/steve/weblog/2004/6/17/php-xml-and-character-encodings-a-tale-of-sadness-rage-and-data-loss xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0); xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1); xml_parse_into_struct($parser, trim($contents), $xml_values); xml_parser_free($parser); if (!$xml_values) return; //Hmm... // Initializations $xml_array = array(); $parents = array(); $opened_tags = array(); $arr = array(); $current = &$xml_array; //Refference // Go through the tags. $repeated_tag_index = array(); //Multiple tags with same name will be turned into an array foreach($xml_values as $data) { unset($attributes, $value); //Remove existing values, or there will be trouble // This command will extract these variables into the foreach scope // tag(string), type(string), level(int), attributes(array). extract($data); //We could use the array by itself, but this cooler. $result = array(); $attributes_data = array(); if (isset($value)) { if ($priority == 'tag') $result = $value; else $result['value'] = $value; //Put the value in a assoc array if we are in the 'Attribute' mode } // Set the attributes too. if (isset($attributes) and $get_attributes) { foreach($attributes as $attr => $val) { if ($priority == 'tag') $attributes_data[$attr] = $val; else $result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr' } } // See tag status and do the needed. if ($type == "open") { // The starting of the tag '<tag>' $parent[$level-1] = &$current; if (!is_array($current) or (!in_array($tag, array_keys($current)))) { // Insert New tag $current[$tag] = $result; if ($attributes_data) $current[$tag .
