looping

Here is a multi-dimensional list of musical groups. The first dimension is group, the second is group members.

Can you loop through each group and output the members joined together with a ", " comma space as a separator, please?

Hi Blessing, you sure can loop through a multidimensional array and output each group member separated by a comma, we can use the built in function that php handles a string which is implode. We can then delimiter each value within the members array by a comma as such implode(",", $member)

Please see my code below:

$groups = [

    'Group1' => [
        'Members' => ['James', 'Jonathan', 'Lewis'],
    ],

    'Group2' => [
        'Members' => ['Jordan', 'Bill', 'Michael'],
    ],
];


foreach($groups as $key => $value){
    echo $key . '</br>';
    foreach($value as $group => $members){

        echo 'Members are: ' . implode(",", $members) . '</br>';

    }
}
