我试图将一些值存储在一个数组中,其中每个元素都有其子元素。
请找到代码:
$children = $user->relations()->wherePlanId($selectplan)->get();
foreach($children as $ch)
{
$child[] = $ch->pivot->child;
$subuser = User::find($ch->pivot->child);
if($subuser){
$subchildren = $subuser->relations()->wherePlanId($selectplan)->get();
foreach($subchildren as $subchild)
{
$subchildid[] = $subchild->pivot->child;
}
}
else
{
$subchildid[] = NULL;
}
}
我想存储类似child['parent_element']['child_element']
预期的数组格式的东西
child[1][2]
child[1][3]
child[1][4]
child[1][5]
child[2][6]
child[2][7]
.
.
child[3][12]
帮帮我。谢谢
假设您的表数据是
tblusers
id name
1 John
2 Doe
3 Carl
4 Jose
5 Bill
6 James
7 Karl
tblparents
id parent child
1 1 2
2 1 3
3 1 4
4 1 5
5 2 6
6 2 7
首先:声明一个变量,该变量将存储您的数组
$child_arr = [];
然后循环你的父数组
foreach($children as $ch) {
// do something
}
在您的父母循环中,孩子是您的循环父母
foreach($subchildren as $subchild) {
$child_arr['your parent id']['your child id'] = 'your desired value';
}
所以你的代码会像这样
$child_arr = [];
$children = $user->relations()->wherePlanId($selectplan)->get();
foreach($children as $ch) {
$parent_id = $ch->pivot->child;
$subuser = User::find($ch->pivot->child);
if($subuser) {
$subchildren = $subuser->relations()->wherePlanId($selectplan)->get();
foreach($subchildren as $subchild) {
$child_id = $subchild->pivot->child;
$child_arr[$parent_id][$child_id] = $subchild;
}
} else {
$child_arr[$parent_id] = null;
}
}
结果将是这样
array(
[1] => array(
[2] => 'value',
[3] => 'value',
[4] => 'value',
[5] => 'value',
),
[2] => array(
[6] => 'value',
[7] => 'value'
),
etc...
)
或者你可以留下'value'
来true
