PHP实现XML与数据格式进行转换类实例

这篇文章主要介绍了PHP实现XML与数据格式进行转换类,实例分析了php进行XML格式数据的方法,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了PHP实现XML与数据格式进行转换类。分享给大家供大家参考。具体如下：

$val) { if ($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 '' $parent[$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 . '_attr'] = $attributes_data; $repeated_tag_index[$tag . '_' . $level] = 1; $current = &$current[$tag]; } else { // There was another element with the same tag name if (isset($current[$tag][0])) { // If there is a 0th element it is already an array $current[$tag][$repeated_tag_index[$tag . '_' . $level]] = $result; $repeated_tag_index[$tag . '_' . $level]++; } else { // This section will make the value an array if multiple tags with the same name appear together $current[$tag] = array($current[$tag], $result); //This will combine the existing item and the new item together to make an array $repeated_tag_index[$tag . '_' . $level] = 2; if (isset($current[$tag . '_attr'])) { // The attribute of the last(0th) tag must be moved as well $current[$tag]['0_attr'] = $current[$tag . '_attr']; unset($current[$tag . '_attr']); } } $last_item_index = $repeated_tag_index[$tag . '_' . $level]-1; $current = &$current[$tag][$last_item_index]; } } elseif ($type == "complete") { // Tags that ends in 1 line '' // See if the key is already taken. if (!isset($current[$tag])) { // New Key $current[$tag] = $result; $repeated_tag_index[$tag . '_' . $level] = 1; if ($priority == 'tag' and $attributes_data) $current[$tag . '_attr'] = $attributes_data; } else { // If taken, put all things inside a list(array) if (isset($current[$tag][0]) and is_array($current[$tag])) { // If it is already an array... // ...push the new element into that array. $current[$tag][$repeated_tag_index[$tag . '_' . $level]] = $result; if ($priority == 'tag' and $get_attributes and $attributes_data) { $current[$tag][$repeated_tag_index[$tag . '_' . $level] . '_attr'] = $attributes_data; } $repeated_tag_index[$tag . '_' . $level]++; } else { // If it is not an array... $current[$tag] = array($current[$tag], $result); //...Make it an array using using the existing value and the new value $repeated_tag_index[$tag . '_' . $level] = 1; if ($priority == 'tag' and $get_attributes) { if (isset($current[$tag . '_attr'])) { // The attribute of the last(0th) tag must be moved as well $current[$tag]['0_attr'] = $current[$tag . '_attr']; unset($current[$tag . '_attr']); } if ($attributes_data) { $current[$tag][$repeated_tag_index[$tag . '_' . $level] . '_attr'] = $attributes_data; } } $repeated_tag_index[$tag . '_' . $level]++; //0 and 1 index is already taken } } } elseif ($type == 'close') { // End of tag '' $current = &$parent[$level-1]; } } return($xml_array); } // Array to XML class array2xml { public $output = "\n"; public $sub_item = array(); public function __construct($array) { $sub_item = array(); $this->output .= $this->xmlmake($array); } public function xmlmake($array, $fk = '') { $xml = ''; global $sub_item; foreach ($array as $key => $value) { if (is_array($value)) { if (is_numeric($key)) { $this->sub_item=array_merge($this->sub_item,array($fk)); $xml .= "" . $this->xmlmake($value, $key) . "{$fk}>"; } else { $xml .= "" . $this->xmlmake($value, $key) . "{$key}>"; } } else { $xml .= "{$value}{$key}>\n"; } } return $xml; } public function output(){ foreach($this->sub_item as $t){ $this->output = str_replace("","",$this->output); $this->output = str_replace("{$t}>{$t}>","{$t}>",$this->output); } return $this->output; } }

希望本文所述对大家的php程序设计有所帮助。
