在PHP中设置多维数组对象中的键和值

All i need is to add [checked] => 1 in some of the arrays on a condition: i have a variable and wants to compare that with the value of 'name' . Ex: If my variable matches with Display or Forwarding, then insertion of a new key and value has to be done.

can anybody tell me how to do that ? I want to directly go to specific index like at 0 or 1 or any index of features array and want to insert new key and value like [checked] => 1

   Array
        (
            [Call xyz] => Array
                (
                    [features] => Array
                        (
                            [0] => Array
                                (
                                    [name] => Display
                                    [display] => webxxx
                                    [category] => x
                                    [uniq_id] => x
                                )

                            [1] => Array
                                (
                                    [name] => Forwarding
                                    [display] => webxxx
                                    [category] => x
                                    [uniq_id] => x
                                )
                        )
               )
           [Hidden] => Array
               (
                   [features] => Array
                      (
                         [0] => Array
                            (
                                [name] => XYZ
                                [display] => webxxx
                                [category] => x
                                [uniq_id] => x
                        )

                        [1] => Array
                          (
                               [name] => ABC
                               [display] => webxxx
                               [category] => x
                               [uniq_id] => x
                          )
                   )

    You will need to access down to the lowest subarray where the name key resides. The first level keys are Call xyz and Hidden. The second level subarrays are both keyed with features. The third level has indexed keys. name is an associative key on the fourth level.

    Once you work your way down to the fourth level, you can concisely write in_array() in your condition to check if the lowest row of data qualifies to receive the new checkbox => 1 element. (Alternatively, you could omit the in_array() call and use: $set3["name"] == "Display" || $set3["name"] == "Forwarding" but this is more verbose and uglier to scale up.)

    Code: (Demo)

    $array = [
        "Call xyz" => [
            "features" => [
                ["name" => "Display", "display" => "webxxx", "category" => "x", "uniq_id" => "x"],
                ["name" => "Forwarding", "display" => "webxxx", "category" => "x", "uniq_id" => "x"]
            ]
        ],
        "Hidden" => [
            "features" => [
                ["name" => "XYZ", "display" => "webxxx", "category" => "x", "uniq_id" => "x"],
                ["name" => "ABC", "display" => "webxxx", "category" => "x", "uniq_id" => "x"]
            ]
        ]
    ];
    
    $whitelist = ["Display", "Forwarding"];
    
    foreach ($array as $key1 => $set1) {
        foreach ($set1 as $key2 => $set2) {
            foreach ($set2 as $key3 => $set3) {
                if (in_array($set3["name"], $whitelist)) {
                    $array[$key1][$key2][$key3]["checkbox"] = 1;    
                }
            }
        }
    }
    
    var_export($array);
    

    Output:

    array (
      'Call xyz' => 
      array (
        'features' => 
        array (
          0 => 
          array (
            'name' => 'Display',
            'display' => 'webxxx',
            'category' => 'x',
            'uniq_id' => 'x',
            'checkbox' => 1,
          ),
          1 => 
          array (
            'name' => 'Forwarding',
            'display' => 'webxxx',
            'category' => 'x',
            'uniq_id' => 'x',
            'checkbox' => 1,
          ),
        ),
      ),
      'Hidden' => 
      array (
        'features' => 
        array (
          0 => 
          array (
            'name' => 'XYZ',
            'display' => 'webxxx',
            'category' => 'x',
            'uniq_id' => 'x',
          ),
          1 => 
          array (
            'name' => 'ABC',
            'display' => 'webxxx',
            'category' => 'x',
            'uniq_id' => 'x',
          ),
        ),
      ),
    )
