php gets all the node paths of json data

Previously we explained the problem of using javascript to get the json data node path. Today we go one step further and explain all the nodes of json data that php gets. Node path

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;

}
