            [role_id] => 4
        )

)

I would like to search through the array and check if level exists and what is the value of the index. I tried the following :

$number = array_column($array, 'level');
 $found_key = array_search('2', $number);

              But I get no response . 

Any help on how I check through the array and check if level exists and what is the value that it's holding?

Answer 1

You can filter your array with something like that:

$filterBy = '2';
$newArray = array_filter($array, function ($var) use ($filterBy) {
    return ($var['level'] == $filterBy); });

print_r($newArray);

$names = array_column($newArray, 'id');

print_r($names);
