获取php数组的最低级别
我从prestashop得到了这个数组:获取php数组的最低级别,php,prestashop,Php,Prestashop,我从prestashop得到了这个数组: [11]=> [id_category] => 11 [children] => [12]=> [id_category] => 12 [children] => [13]=> [id_category] => 14 我想得到这个数组的最后一级,即13数组。为了获取这个数组,我使用Category::getN
[11]=>
[id_category] => 11
[children] =>
[12]=>
[id_category] => 12
[children] =>
[13]=>
[id_category] => 14
我想得到这个数组的最后一级,即13数组。为了获取这个数组,我使用Category::getNestedCategories 尝试以下操作:
$tree = [
'id_category' => 11,
'children' => [
12 => [
'id_category' => 12,
'children' => [
13 => [
'id_category' => 13,
'children' => [
14 => [
'id_category' => 14
]
]
],
15 => [
'id_category' => 15
]
]
]
]
];
function findMaxDepth(array $data): int
{
$maxDepth = 0;
if (isset($data['children'])) {
// if there'are children of the node collect maxs on this level
foreach ($data['children'] as $child) {
// go on next level
$depth = findMaxDepth($child);
if ($maxDepth < $depth) {
$maxDepth = $depth;
}
}
}
return $maxDepth + 1;
}
结果将是4尝试以下功能:-
function findLowestChild($arr, $level = 0, $lowestArr = ['level'=>0, 'value'=> null]){
if(isset($arr['children']) && is_array($arr['children'])) {
$level++;
foreach($arr['children'] as $childArr) {
$lowestArr = findLowestChild($childArr, $level, $lowestArr);
}
} else {
if($lowestArr['level'] < $level) {
$lowestArr['level'] = $level;
$lowestArr['value'] = $arr;
}
}
return $lowestArr;
}
函数findLowestChild($arr,$level=0,$lowstar=['level'=>0,'value'=>null]){
if(isset($arr['children'])和&is_数组($arr['children'])){
$level++;
foreach($arr['children']作为$childArr){
$lowstarr=findLowestChild($childArr,$level,$lowstarr);
}
}否则{
如果($Lowstarr['level']<$level){
$Lowstar['level']=$level;
$lowstarr['value']=$arr;
}
}
返回$Lowstar;
}
将其称为findLowestChild($yourray);
它将为您提供级别值以及最低值数组。的可能副本尽管上面的链接可能会为您提供额外的节点,但这可能是一个有用的起点。如果您有这样的数组,则无论使用何种引擎,解决方案都可能是相同的。但是如果在某个级别上有两个或多个子分支,您希望得到什么??
function findLowestChild($arr, $level = 0, $lowestArr = ['level'=>0, 'value'=> null]){
if(isset($arr['children']) && is_array($arr['children'])) {
$level++;
foreach($arr['children'] as $childArr) {
$lowestArr = findLowestChild($childArr, $level, $lowestArr);
}
} else {
if($lowestArr['level'] < $level) {
$lowestArr['level'] = $level;
$lowestArr['value'] = $arr;
}
}
return $lowestArr;
}
