问题是我想做：下面的输出请帮助：-
{
"result": "SUCCESS",
"records": [
{
country : india,
states : [
{
state : karnataka
cities : [bangalore,mysore]
},
{
state : Tamilnadu
cities : [chennai,coimbutore]
}
]
},
{
country : US,
states : [
{
state : ohiao
cities : [city 1,city 2]
},
{
state : california
cities : [city 1,city 2]
}
]
}
]
}
我试过循环这个。
foreach ($returnData as $key => $value) {
$actual_response[$value['country']][$value['state']][]=$value['city'];
}
解决方案
你可以试试这个把这个代码放在你的数组下面并运行。
function nested($item)
{
if (count($item) > 1)
{
$key = array_shift($item);
return array($key => nested($item));
}
else
{
return $item;
}
}
$finalArr = array();
foreach($arr as $data)
{
$finalArr = array_merge_recursive($finalArr, nested($data));
}
$finalArr = array_values($finalArr);
echo json_encode(array("result"=>"SUCCESS" ,"records"=>$finalArr) );exit;
