如何动态计算类别级别。这是一个PHP数组，这可以在用户更改菜单结构时更改，但目前这是一个结构，我只想知道主要类别，邮件类别和主要类别中的子类别有多少级别＆ ＃34;品牌＆＃34 ;.这是我的数组结构。

答案 0 :(得分：1)
你可以递归地执行此操作：
function countChildren($array) {
$children = 0;
if (isset($array["children"]) {
$children = count($array["children"]);
foreach ($array["children"] as $subarray) {
$children += countChildren($subarray);
}
}
return $children;
}
只计算你可以做的水平：
function countChildrenLevels($array) {
$children = 0;
if (isset($array["children"]) {
$sublevels = [];
foreach ($array["children"] as $subarray) {
$sublevels[] = countChildren($subarray);
}
$children = 1 + max($sublevels);
}
return $children;
}
