How to insert a new array element in parent array in foreach

I have an array $categories as follows;

Array
    (
        [0] => Array
            (
                [category_id] => 0
            )

        [1] => Array
            (
                [category_id] => 3
            )
    )

I want to apply some condition in foreach as follows;

Note: following condition is not working;

foreach ($categories as $key=> $category)
{
    if($category['category_id']===0)
    {
        $categories[$key]['category_name'] = 'NA';
    }
    else
    {
        $categories[$key]['category_name'] = 'something';
    }
}

so my expected result will become;

Array
    (
        [0] => Array
            (
                [category_id] => 0
                [category_name] => NA
            )

        [1] => Array
            (
                [category_id] => 3
                [category_id] => something
            )
    )

In the array there is possible that 0 could be string you are checking with === operator which will match string with its datatype also.

You can check its datatype if needed using gettype($value).

For current issue try this:

/* Compare value without checking its datatype */
if($category['category_id'] == 0)  /* replace === to == */
{
    $categories[$key]['category_name'] = 'NA';
}
else
{
    $categories[$key]['category_name'] = 'something';
}
