根据最底部的示例数组,我希望能够在数组内附加每个嵌入数组的深度.例如:
array ( 53 => array ( 'title' => 'Home', 'path' => '', 'type' => '118', 'pid' => 52, 'hasChildren' => 0, ),
根据下面显示的示例数组具有一个深度,所以它现在应该如下所示:
array ( 53 => array ( 'title' => 'Home', 'path' => '', 'type' => '118', 'pid' => 52, 'hasChildren' => 0, 'depth' => 1, ),
等等...
我所做的所有递归数组函数尝试都非常令人尴尬.但是我查看了具有getDepth函数的RecursiveArrayIterator.我对如何将它附加到当前数组感到困惑...非常感谢任何帮助,谢谢.

我假设有另一个数组(在顶部没有包含在你的示例代码中.这样的东西?
function array_set_depth($array, $depth = -1) { $subdepth = $depth + 1; if ($depth < 0) { foreach ($array as $key => $subarray) { $temp[$key] = array_set_depth(($subarray), $subdepth); } } if ($array['hasChildren'] && isset($array['children'])) { foreach ($array['children'] as $key => $subarray) { $temp[$key] = array_set_depth($subarray, $subdepth); } $array['children'] = $temp; } $array['depth'] = $depth; return $array; }
用法示例,我将您的数组设置为值$ a:
$b = array_set_depth($a); print_r($b);
编辑:
要在孩子们之前设置深度以进行漂亮的打印,您可以这样做:
function array_set_depth($array, $depth = -1) { $subdepth = $depth + 1; if ($depth < 0) { foreach ($array as $key => $subarray) { $temp[$key] = array_set_depth(($subarray), $subdepth); } return $temp; } $array['depth'] = $depth; if ($array['hasChildren'] && isset($array['children'])) { foreach ($array['children'] as $key => $subarray) { $temp[$key] = array_set_depth($subarray, $subdepth); } unset($array['children']); $array['children'] = $temp; } return $array; }

像这样的递归函数应该这样做吗?
function setDepth(&$a, $depth) { $a['depth']=$depth; foreach($a as $key=>$value) { if (is_array($value)) setDepth($a[$key], $depth+1); } }
需要注意的是,数组是通过引用传递的,因此我们可以对其进行修改.请注意,我们还在对setDepth的递归调用中使用此引用.虽然我使用foreach是为了方便,但$ value变量是一个副本,并且将它传递给setDepth只会在foreach循环的范围内进行短暂的更改.
