how to get value from array in laravel
提问by Shojib Flamon
In laravel i get this type of array from where query. i want to get only those menu where parent is 0;
在 Laravel 中,我从 where 查询中获得了这种类型的数组。我只想获取父项为 0 的菜单;
$memus = Menu::where('parent', 0)->get()->toArray();
Array
(
[0] => Array
(
[id] => 13
[name] => Movies
[parent] => 0
[deleted_at] =>
[created_at] => 2015-04-07 02:48:48
[updated_at] => 2015-04-07 02:48:48
)
[1] => Array
(
[id] => 16
[name] => zxcvxc
[parent] => 0
[deleted_at] =>
[created_at] => 2015-04-07 02:53:26
[updated_at] => 2015-04-07 03:03:39
)
[2] => Array
(
[id] => 17
[name] => alsdkf
[parent] => 0
[deleted_at] =>
[created_at] => 2015-04-07 02:53:41
[updated_at] => 2015-04-07 03:02:04
)
)
So how to get particular value from this array

和echo $abc->id
,但不能上网

You can just do this:
你可以这样做:
echo $memus[0]['name'];
Or if you want all of them
或者如果你想要所有这些
foreach ($memus as $memu) {
echo $memu['name'];
}

The arrow ($object->property)
notation is for objects.
箭头($object->property)
符号用于对象。
The notation for accessing array elements is $array[$index][$key]
.
访问数组元素的符号是$array[$index][$key]
。
So in your case, to access the name key in your second array would be:
因此,在您的情况下,要访问第二个数组中的 name 键将是:
echo($menu[1]['name'])
, in your example this would echo the string 'zxcvxc'.
echo($menu[1]['name'])
,在您的示例中,这将回显字符串“zxcvxc”。

You can use collections in laravel 5
您可以在 Laravel 5 中使用集合
collect($arrayName);
$filtered = $arrayName->where('parent', 0);
$filtered->all();
Hope this will help. If not please let me know.
希望这会有所帮助。如果没有,请告诉我。

To get a particular value
获取特定值
{{memus[0]->id}}
回答by Brahms
If you want to access some array's data just do
$array_name[index]->key
in the controller or in the view.
如果您想访问某个数组的数据,只需
$array_name[index]->key
在控制器或视图中执行即可。
Index is usually an integer and the key is what you are looking to extract.
For instance, we would do this on your array: $menu_zero = $menus[0]->id;
it would give us 13 and $menu_name_zero = $menu[0]->name;
would give the name.
索引通常是一个整数,键是您要提取的内容。例如,我们会在您的数组上执行此操作:$menu_zero = $menus[0]->id;
它会给我们 13 并$menu_name_zero = $menu[0]->name;
会给出名称。

You can do it this way:
你可以这样做:
For single item you can do this:
对于单个项目,您可以这样做:
echo ($menus[0]['parent'] == 0) ? $menus[0]['name'] : '';
With foreach
loop:
带foreach
循环:
foreach ($menus as $menu) {
if($menu['parent'] == 0){
echo $menu['name'];
}
}
