按类别分组数组

Question

I am facing problem In grouping array with the Key:- I have an php array Which has following elecment in it.

$array = array(
    '0' => array ( 'id' => 'food,Travel', 'names' => 'chimpanzee' ),
    '1' => array ( 'id' => 'food', 'name' => 'meeting' ),
    '2' => array ( 'id' => 'Z1', 'name' => 'dynasty' ),
    '3' => array ( 'id' => 'X', 'name' => 'chocolate' ),
    '4' => array ( 'id' => 'Travel', 'name' => 'bananas' ),
    '5' => array ( 'id' => 'Travel', 'name' => 'fantasy' ),
    '6' => array ( 'id' => 'Travel', 'name' => 'football' )
);

When I try with following code:-

$newarray= array();
foreach($array as $key => $value){
    $newarray[$value['id']][$key] = $value;
}

I am getting below result Array Here food,travel is created another array but I want to please those to respective category "Food goes to food" and travel goes to travel"

 (
    [food,Travel] => Array
        (
            [0] => Array
                (
                    [id] => food,Travel
                    [names] => chimpanzee
                )

        )

    [food] => Array
        (

[1] => Array

                    [id] => food,Travel
                    [names] => chimpanzee
                )  
(
                    [id] => food
                    [name] => meeting
                )


        )

    [Z1] => Array
        (
            [2] => Array
                (
                    [id] => Z1
                    [name] => dynasty
                )

        )

    [X] => Array
        (
            [3] => Array
                (
                    [id] => X
                    [name] => chocolate
                )

        )

    [Travel] => Array
        (
            [4] => Array
                (
                    [id] => Travel
                    [name] => bananas
                )

            [5] => Array
                (
                    [id] => Travel
                    [name] => fantasy
                )

            [6] => Array
                (
                    [id] => Travel

$newArray= [];

    $keys = explode(',', $value['id']);

    $tmpKeys = array_keys($value);
    $valueKey = array_pop($tmpKeys);
