I have variable of array. Want to make that array to string using comma seperator.

$variable = array:[
0 => array:1 [
"numbers" => "TS-001-0005"
]
1 => array:1 [
"numbers" => "TS-001-0006"
]
2 => array:1 [
"numbers" => "TS-001-0007"
]
3 => array:1 [
"numbers" => "TS-001-0008"
]
4 => array:1 [
"numbers" => "TS-001-0009"

Need to do this array in below format. tring using implode function but

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

If anyone have idea how to do this please let me know.

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')));

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

Import:

use Illuminate\Support\Arr;

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
