（PHP）我有这个数组：

Array
(
    [101] => Category Level One
    [112] =>    Second Name Category
    [173] =>       Suzete,Biberoane
    [177] =>       Carucioare
    [178] =>       Centre Activitati, Carusele
    [180] =>       Scaune Auto Accesorii
    [182] =>       Mobilier Bebelusi
    [113] =>    Jucarii de Exterior
    [203] =>       Leagane, ToboganeBalansoare
    [119] =>    Jucarii Educative
    [147] =>    Vehicule, BicicleteTriciclete
    [272] =>       Biciclete Triciclete
    [274] =>       Vehicule Diverse
    [102] => Category Level One Blabla
    [115] =>    Another Second Category
    [276] =>       Laptopuri
    [277] =>       Tablete
    [278] =>       Accesorii Laptopuri
    [281] =>          Genti Laptopuri
    [282] =>          Memorii Laptopuri
    [283] =>          Coolere Laptopuri
    [279] =>       Accesorii Tablete
    [116] =>    Yet Another Second Categ
    [287] =>       Desktop PC
    [288] =>       Monitoare
    [117] =>    Componente & Periferice
    [289] =>       Componente PC
)

现在这是一个类别列表，包括 parents 和 children 。如何根据空格数 / 来判断一个节点的父节点。

我想把它放到一个 mysql 数据库中，我需要知道每个类别的值/名称/父级。

我希望这就是你要找的。

<?php
$arr = array
    (
    101 => 'Category Level One',
    112 => '&nbsp;&nbsp;&nbsp;Second Name Category',
    173 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Suzete,Biberoane',
    177 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Carucioare',
    178 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Centre Activitati, Carusele',
    180 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Scaune Auto Accesorii',
    182 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mobilier Bebelusi',
    113 => '&nbsp;&nbsp;&nbsp;Jucarii de Exterior',
    203 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Leagane, ToboganeBalansoare',
    119 => '&nbsp;&nbsp;&nbsp;Jucarii Educative',
    147 => '&nbsp;&nbsp;&nbsp;Vehicule, BicicleteTriciclete',
    272 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Biciclete Triciclete',
    274 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Vehicule Diverse',
    102 => 'Category Level One Blabla',
    115 => '&nbsp;&nbsp;&nbsp;Another Second Category',
    276 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Laptopuri',
    277 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Tablete',
    278 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Accesorii Laptopuri',
    281 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Genti Laptopuri',
    282 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Memorii Laptopuri',
    283 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Coolere Laptopuri',
    279 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Accesorii Tablete',
    116 => '&nbsp;&nbsp;&nbsp;Yet Another Second Categ',
    287 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Desktop PC',
    288 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Monitoare',
    117 => '&nbsp;&nbsp;&nbsp;Componente &amp; Periferice',
    289 => '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Componente PC',
);

foreach($arr as $k=>$v)
{
    //if(!strpos($v,'&nbsp;'))

    switch(substr_count($v,'&nbsp;'))
    {
        case 0:
            echo "<br>Parent Node found at $k : $v";
            break;

        case 3:
            echo "<br>Child Found at $k : $v";

            break;

        case 6:
            echo "<br>Sub-Child Found at $k : $v";

            break;
    }

}

输出 ：
