轉換嵌套集數組使用PHP

我有一個嵌套集模型數組https://en.wikipedia.org/wiki/Nested_set_model，我需要將數組轉換爲具有無限級別的json父 - 孩子。轉換嵌套集數組使用PHP

陣列例如：

array(6) { 
    [0]=> 
    array(8) { 
    ["title"]=> 
    string(5) "cat 2" 
    ["type"]=> 
    string(3) "url" 
    ["class_name"]=> 
    string(0) "" 
    ["content"]=> 
    string(6) "value2" 
    ["id"]=> 
    string(3) "128" 
    ["lft"]=> 
    string(1) "1" 
    ["rgt"]=> 
    string(1) "4" 
    ["depth"]=> 
    string(1) "0" 
    } 
    [1]=> 
    array(8) { 
    ["title"]=> 
    string(5) "sub 1" 
    ["type"]=> 
    string(3) "url" 
    ["class_name"]=> 
    string(0) "" 
    ["content"]=> 
    string(6) "value1" 
    ["id"]=> 
    string(3) "129" 
    ["lft"]=> 
    string(1) "2" 
    ["rgt"]=> 
    string(1) "3" 
    ["depth"]=> 
    string(1) "1" 
    } 
    [2]=> 
    array(8) { 
    ["title"]=> 
    string(5) "cat 1" 
    ["type"]=> 
    string(3) "url" 
    ["class_name"]=> 
    string(0) "" 
    ["content"]=> 
    string(6) "value1" 
    ["id"]=> 
    string(3) "130" 
    ["lft"]=> 
    string(1) "5" 
    ["rgt"]=> 
    string(2) "10" 
    ["depth"]=> 
    string(1) "0" 
    } 
    [3]=> 
    array(8) { 
    ["title"]=> 
    string(5) "sub 2" 
    ["type"]=> 
    string(3) "url" 
    ["class_name"]=> 
    string(0) "" 
    ["content"]=> 
    string(6) "value2" 
    ["id"]=> 
    string(3) "131" 
    ["lft"]=> 
    string(1) "6" 
    ["rgt"]=> 
    string(1) "9" 
    ["depth"]=> 
    string(1) "1" 
    } 
    [4]=> 
    array(8) { 
    ["title"]=> 
    string(5) "sub 3" 
    ["type"]=> 
    string(3) "url" 
    ["class_name"]=> 
    string(0) "" 
    ["content"]=> 
    string(6) "value3" 
    ["id"]=> 
    string(3) "132" 
    ["lft"]=> 
    string(1) "7" 
    ["rgt"]=> 
    string(1) "8" 
    ["depth"]=> 
    string(1) "2" 
    } 
    [5]=> 
    array(8) { 
    ["title"]=> 
    string(4) "item" 
    ["type"]=> 
    string(3) "url" 
    ["class_name"]=> 
    string(0) "" 
    ["content"]=> 
    string(6) "value1" 
    ["id"]=> 
    string(3) "133" 
    ["lft"]=> 
    string(2) "11" 
    ["rgt"]=> 
    string(2) "12" 
    ["depth"]=> 
    string(1) "0" 
    } 
}

JSON例如：

[{"name":"Cat 1","value":"value1","children":[{"name":"sub 2", "value":"value2","children":[{"name":"sub 3", "value":"value 3"}]}]}, {"name":"Cat 2","value":"value 2","children":[{"name":"sub 1", "value":"value1"}]},{"name":"item","value":"value1"}]

有人可以幫我創建一個函數來完成轉換？

答案你想要的代碼？ –

我看到深度，但不明白親子關係。在哪裏？ – splash58
