PHP - create new array for specific keys

Question

I have the following array, and I only want to return keys that are carousel_, NOT _carousel_ or the word itself carousel:

Array ( 
    [test_field] => 

    [_test_field] => field_61d60b3a91441 

    [carousel_0_slide] => 42 

    [_carousel_0_slide] => field_61d35ea917c1b 

    [carousel_1_slide] => 42 

    [_carousel_1_slide] => field_61d35ea917c1b 

    [carousel_2_slide] => 42 

    [_carousel_2_slide] => field_61d35ea917c1b 

    [carousel_3_slide] => 42 

    [_carousel_3_slide] => field_61d35ea917c1b 

    [carousel] => 4 

    [_carousel] => field_61d35e3617c1a 
)

I've tried looping through it but I haven't been able to specifically target the carousel_ without also including the rest, or really even correctly.

Any help would greatly be appreciated it.

use [array_filter](https://www.php.net/manual/en/function.array-filter.php) https://3v4l.org/GJQbd - you should add what you have tried — Lawrence Cherone, Jan 05 '22 at 21:47
Do you want to include only the `carousel_ key` or it with `carousel_some_other_words`? — trokymchuk, Jan 05 '22 at 21:50

one option is to use https://www.php.net/manual/en/function.preg-grep.php

$keys = preg_grep('/^console_/',$your_array);
$my_array = [];
foreach ($keys as $k) {
    $my_array[$k] = $your_array[$k];
}
