在php中以ul li格式解析树数据有一些困难

Question

我正在尝试创建试算平衡我以某种方式在我的数组中实现了树视图，现在我想打印我的代码但不知道如何制作树，因为我不知道将来我能得到多少孩子我不太擅长递归下面是我的树准备数组，我还附上了我可以通过 foreach 循环制作但卡在子节点中的结果我可以通过 foreach 制作子节点，但问题是它不是最好的方法请按照我的数组帮助我打印我的树结构数据。任何帮助，将不胜感激。

这里我的树数组看起来像：Tree Array

我的结果看起来像这样，这只是一个数组的根节点，我使用 jstree 来显示层次结构。

我在这里解决了我自己选择什么方法我将子数组提取到其他数组中，并在该数组上使用我的递归来做魔术。

<? $array = $trial_tree["children"]; ?>


$trial_balance_tree = $this->trees;

$total_opening_debit = 0;
$total_opening_credit = 0;

$total_opening = 0;
$total_closing = 0;

function makeListItems($a) {
    global $total_opening_debit,$total_opening_credit,$total_credit,$total_debit,$total_closing_debit,$total_closing_credit,$total_opening,$total_closing;
    $out = '';
    foreach($a as $val) {
    //print_r($key); echo is_array($val);exit;
        if($val["id"] > 0)
        {
            $out .= '<li>';
            $out .= "<span class='first'>" . $val["name"] . "</span>";

                            $out .= format_currency($val["opening_debit"] - $val["opening_credit"], 2) . " Dr.";
                        }
                        elseif ($val["opening_credit"] > $val["opening_debit"])

                        if ($val["opening_debit"] + $val["period_debit"] > $val["opening_credit"] + $val["period_credit"])

                        }
                        else
                        {

                        }
                        $out .= $closing;

                        //calculate all opeing and closing debit & credit.
                        if ($val["opening_debit"] + $val["period_debit"] > $val["opening_credit"] + $val["period_credit"])

                        }

                        if ($val["opening_credit"] + $val["period_credit"] > $val["opening_debit"] + $val["period_debit"])
                        {
                            $total_closing_credit += ($val["opening_credit"] + $val["period_credit"] - $val["opening_debit"] - $val["period_debit"]);
                        }
             $out .= "</span>";

            if(array_key_exists('children', $val)) {

    $out .= '</ul>';

    return $out;
}
?>
<table style="width:100%;background-color: #A5C6DB;">
    <tr>
        <th class="table_first" style="width:42.5%;">Ledger Name</th>
        <th class="table_other" style="width:14.7%;">Opening</th>

<?

现在我的视图看起来像这样，这正是我想要的。
