php获取json数据所有的节点路径

　　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

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

$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%5B%5D=food_activity&extras%5B%5D=restaura

$ret = iterTree($data);

print_r($ret);
