我一直在使用ALMOST为我工作的功能,我来自 HERE ,但它添加了一个我不想要的额外数组。信息存储在我的数据库中,如下所示:
方式
private function buildCategories($array,$parent)
{
$result = array();
foreach($array as $row)
{
if($row['parent'] == $parent)
{
$result[$row['category_name']] = $this->buildCategories($array,$row['category_id']);
}
}
return $result;
}
$json = json_encode($this->buildCategories($array,NULL));
return $json;
我想要这个:
{"reloading":{"components","presses and dies","tumblers & scales","tools & accessories","shotshell reloading"}
但我得到的是:
{"reloading":{"components":[],"presses and dies":[],"tumblers & scales":[],"tools & accessories":[],"shotshell reloading":[]}
注意:我问了一个类似的问题,但不是建立一个关联数组。因为它不像我最初的要求,我认为需要另一个线程。
答案 0 :(得分:6)
你可以得到这个:
{"reloading":["components","presses and dies","tumblers & scales","tools & accessories","shotshell reloading"]}
代码:
private function buildCategories($array,$parent)
{
$result = array();
foreach($array as $row) {
if($row['parent'] == $parent) {
if ($row['parent'] == NULL) {
$result[$row['category_name']] = $this->buildCategories($array,$row['category_id']);
} else {
$result[] = $row['category_name'];
}
}
}
return $result;
}
