配列の格納方法について
解決したいこと
PHPで都道府県のjsonデータを読み込み、下記のような配列を作成したいです。
そこでforeachとifを使い順次配列に格納したいのですが、一部しか格納されません。
例：下記に記載のif($key <= 7）であれば、キー7しか格納されません。
こちらの解決方法を教えてください。
【作成したい配列】
[
"北海道地方" => [
"県名" => [県名1, ...],
"市町村名" => [市町村名1, ...],
...
]
###jsonデータ
[{
"01": {
"id": "01",
"name": "北海道",
"short": "北海道",
"kana": "ホッカイドウ",
"en": "hokkaido",
"city":[
{"citycode":"0010001","city":"札幌市中央区"},

{"citycode":"0010003","city":"札幌市東区"},
{"citycode":"0010004","city":"札幌市白石区"},
{"citycode":"0010005","city":"札幌市豊平区"},
・・・・
]
},
"02": {
"id": "02",
"name": "青森県",
"short": "青森",
"kana": "アオモリケン",
"en": "aomori",
"city":[
{"citycode":"0020001","city":"青森市"},

{"citycode":"0020003","city":"八戸市"},
{"citycode":"0020004","city":"黒石市"},
{"citycode":"0020005","city":"五所川原市"},
