php中如何实现xml转换成json

这篇文章主要介绍了php中如何实现xml转换成json，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

1、创建一个PHP示例文件。

2、找到需要转换的xml文件。

3、通过"function xmlToArray($xml, $options = array()) {...}"方法将其转换成json即可。

实例

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    );}
