    You can simply achieve using the flatten and the join methods provided by Laravel framework, this way:

    Import:

    use IlluminateSupportArr;

    Then:

    Arr::join(Arr::flatten($variable), ',')

    Explanation:

    Arr::flatten will return a new single level array from multi level array by removing all the keys except values. While, Arr::join will return a string, joining all the array elements/values separated by a comma ,.

    Output:

    TS-001-0005,TS-001-0006,TS-001-0007,TS-001-0008,TS-001-0009

    So, in your last question, you attempted to use PHP‘s implode() function. This is fine, but doesn’t work well on nested arrays. In your case, you don’t need a nested Array:

    <input type="text" name="batch_numbers[0]"/>
<input type="text" name="batch_numbers[1]"/>
<input type="text" name="batch_numbers[2]"/>

    Given those inputs, to get a CSV of their values, you can simply use:

    $csv = implode(',', $request->input('batch_numbers'));

    Proper nested inputs would be:

    <input type="text" name="batch_numbers[0]['numbers']"/>
<input type="text" name="batch_numbers[1]['numbers']"/>
<input type="text" name="batch_numbers[2]['numbers']"/>

    To implode() this, you’d need a different method, maybe something like:

    $csv = implode(',', array_column($request->input('batch_numbers'), 'numbers')));
