php获取json数据所有的节点路径，php获取json节点
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($data) && empty($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) && !empty($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[]=food_activity&extras[]=restaurant_activity&extras[]=certification&fields[]=id&fields[]=name&fiel

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