php xml怎么转化成json?
XML 转 JSON
以下代码演示了如何将一个 xml 文件的数据转换为 Json 格式数据:
function xmlToArray($xml, $options = array()) { $defaults = array( 'namespaceSeparator' => ':',//you may want this to be something other than a colon 'attributePrefix' => '@', //to distinguish between attributes and nodes with the same name 'alwaysArray' => array(), //array of xml tag names which should always become arrays 'autoArray' => true, //only create arrays for tags which appear more than once 'textContent' => '$', //key used for the text content of elements 'autoText' => true, //skip textContent key if node has no attributes or child nodes 'keySearch' => false, //optional search and replace on tag and attribute names 'keyReplace' => false //replace values for above search values (as passed to str_replace()) ); $options = array_merge($defaults, $options); $namespaces = $xml->getDocNamespaces(); $namespaces[''] = null; //add base (empty) namespace //get attributes from all namespaces $attributesArray = array(); foreach ($namespaces as $prefix => $namespace) { foreach ($xml->attributes($namespace) as $attributeName => $attribute) { //replace characters in attribute name if ($options['keySearch']) $attributeName = str_replace($options['keySearch'], $options['keyReplace'], $attributeName); $attributeKey = $options['attributePrefix'] . ($prefix ? $prefix . $options['namespaceSeparator'] : '') . $attributeName; $attributesArray[$attributeKey] = (string)$attribute; } } //get child nodes from all namespaces $tagsArray = array(); foreach ($namespaces as $prefix => $namespace) { foreach ($xml->children($namespace) as $childXml) { //recurse into child nodes $childArray = xmlToArray($childXml, $options); list($childTagName, $childProperties) = each($childArray); //replace characters in tag name if ($options['keySearch']) $childTagName = str_replace($options['keySearch'], $options['keyReplace'], $childTagName); //add namespace prefix, if any if ($prefix) $childTagName = $prefix . $options['namespaceSeparator'] . $childTagName; if (!isset($tagsArray[$childTagName])) { //only entry with this key //test if tags of this type should always be arrays, no matter the element count $tagsArray[$childTagName] = in_array($childTagName, $options['alwaysArray']) || !$options['autoArray'] ? array($childProperties) : $childProperties; } elseif ( is_array($tagsArray[$childTagName]) && array_keys($tagsArray[$childTagName]) === range(0, count($tagsArray[$childTagName]) - 1) ) { //key already exists and is integer indexed array $tagsArray[$childTagName][] = $childProperties; } else { //key exists so convert to integer indexed array with previous value in position 0 $tagsArray[$childTagName] = array($tagsArray[$childTagName], $childProperties); } } } //get text content of node $textContentArray = array(); $plainText = trim((string)$xml); if ($plainText !== '') $textContentArray[$options['textContent']] = $plainText; //stick it all together $propertiesArray = !$options['autoText'] || $attributesArray || $tagsArray || ($plainText === '') ? array_merge($attributesArray, $tagsArray, $textContentArray) : $plainText; //return node as array return array( $xml->getName() => $propertiesArray ); }
使用实例
$xmlNode = simplexml_load_file('example.xml'); $arrayData = xmlToArray($xmlNode); echo json_encode($arrayData);
