这篇文章主要介绍了php获取json数据所有的节点路径的方法和实例,有需要的小伙伴可以参考下。
之前我们讲解过使用javascript获取json数据节点路径的问题,今天我们更进一步,讲解下php获取json数据所有的节点路径
- <?php
- function iterTree($data) {
- $retData = array();
- $data = json_decode($data, true);
- if (!is_array($data) && emptyempty($data)) {
- echo 'error !' ."n";
- } else {
- $queue = array();
- foreach ($data as $field => $value) {
- $queue[] = $field;
- }
- $head = 0;
- $tail = count($queue);
- while ($head < $tail) {
- $field = $queue[$head++];
- $path = explode("/", $field);
- $tmpData = &$data;
- foreach ($path as $key => $ph) {
- $tmpData = &$tmpData[$ph];
- }
- if (is_array($tmpData) && !emptyempty($tmpData)) {
- $newField = $field;
- foreach ($tmpData as $curField => $curValue) {
- $newField = $field . '/' . $curField;
- $queue[$tail++] = $newField;
- }
- } else {
- $retData[] = $field;
- }
- }
- }
- return $retData;
- }
- //测试数据
- $data = file_get_contents("http://restapi.ele.me/v1/restaurants?extras%5B%5D=food_activity&extras%5B%5D=restaurant_activity&extras%5B%5D=certification&fields%5B%5D=id&fields%5B%5D=name&fiel

- $ret = iterTree($data);
- print_r($ret);
