打印如下：

代码如下

复制代码

array(7) {
[0] => array(5) {
    ["id"] => string(1) "4"
    ["fzname"] => string(12) "山猫小号"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "0"
    ["time"] => string(10) "1413359977"
}
[1] => array(5) {
    ["id"] => string(1) "5"
    ["fzname"] => string(12) "山猫一组"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "4"
    ["time"] => string(10) "1413361206"
}
[2] => array(5) {
    ["id"] => string(1) "6"
    ["fzname"] => string(12) "山猫二组"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "4"
    ["time"] => string(10) "1413361225"
}
[3] => array(5) {
    ["id"] => string(1) "7"
    ["fzname"] => string(15) "山猫一组子"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "5"
    ["time"] => string(10) "1413361388"
}
[4] => array(5) {
    ["id"] => string(1) "8"
    ["fzname"] => string(15) "山猫一组子"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "5"
    ["time"] => string(10) "1413361409"
}
[5] => array(5) {
    ["id"] => string(1) "9"
    ["fzname"] => string(16) "山猫一组子3"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "5"
    ["time"] => string(10) "1413361460"
}
[6] => array(5) {
    ["id"] => string(2) "10"
    ["fzname"] => string(15) "山猫二组子"
    ["userid"] => string(2) "12"
    ["pid"] => string(1) "6"
    ["time"] => string(10) "1413361506"
}
}

结果：

打印如下：

代码如下

复制代码

array(1) {
[0] => array(5) {
    ["id"] => string(1) "4"
    ["fzname"] => string(12) "山猫小号"
    ["userid"] => string(2) "12"
    ["pid"] => array(2) {
      [0] => array(5) {
        ["id"] => string(1) "5"
        ["fzname"] => string(12) "山猫一组"
        ["userid"] => string(2) "12"
        ["pid"] => array(3) {
          [0] => array(5) {
            ["id"] => string(1) "7"
            ["fzname"] => string(15) "山猫一组子"
            ["userid"] => string(2) "12"
            ["pid"] => string(0) ""
            ["time"] => string(10) "1413361388"
          }
          [1] => array(5) {
            ["id"] => string(1) "8"
            ["fzname"] => string(15) "山猫一组子"
            ["userid"] => string(2) "12"
            ["pid"] => string(0) ""
            ["time"] => string(10) "1413361409"
          }
          [2] => array(5) {
            ["id"] => string(1) "9"
            ["fzname"] => string(16) "山猫一组子3"
            ["userid"] => string(2) "12"
            ["pid"] => string(0) ""
            ["time"] => string(10) "1413361460"
          }
        }
        ["time"] => string(10) "1413361206"
      }
      [1] => array(5) {
        ["id"] => string(1) "6"
        ["fzname"] => string(12) "山猫二组"
        ["userid"] => string(2) "12"
        ["pid"] => array(1) {
          [0] => array(5) {
            ["id"] => string(2) "10"
            ["fzname"] => string(15) "山猫二组子"
            ["userid"] => string(2) "12"
            ["pid"] => string(0) ""
            ["time"] => string(10) "1413361506"
          }
        }
        ["time"] => string(10) "1413361225"
      }
    }
    ["time"] => string(10) "1413359977"
}
}

工用到两个函数1生成树形代码：

代码如下	复制代码
function getTree($data, $pId) { $tree = ''; foreach($data as $k => $v) { if($v['pid'] == $pId) { $v['pid'] = $this->getTree($data, $v['id']); $tree[] = $v; //unset($data[$k]); } } return $tree; }

函数2转化为html代码：

代码如下	复制代码
function procHtml($tree) { $html = ''; foreach($tree as $t) { if($t['pid'] == '') { $html .= " {$t['fzname']} "; } else { $html .= " ".$t['fzname']; $html .= $this->procHtml($t['pid']); $html = $html." "; } } return $html ? ' '.$html.' ' : $html ; }
