I have an array like the one below

array:4 [▼

  0 => array:3 [▼

    0 => array:2 [▼

      "url" => "https://domain.com.vn"

      "value" => "Keyword B3"

    ]

    1 => array:2 [▼

      "url" => "https://domain.com.vn"

      "value" => "[IMAGES 1]"

    ]

  ]

  1 => array:3 [▼

    0 => array:2 [▼

      "url" => "https://domain-4.com.vn"

      "value" => "D1"

    ]

    1 => array:2 [▼

      "url" => "https://domain-4.com.vn"

      "value" => "E3"

    ]

  ]

]

I want to combine the above 2 arrays into 1 array as follows (number of items in 2 arrays is always equal):

$result = [

    [

        "url" => [

            "https://domain.com.vn",

            "https://domain-4.com.vn"

        ]

        "value" => [

            "Keyword B3",

            "D1"

        ]

    ],

    [

        "url" => [

            "https://domain.com.vn",

            "https://domain-4.com.vn"

        ],

        "value" => [

            "[IMAGES 1]",

            "E3"

        ]

    ]

]

I have searched a lot but have not found a solution yet. Thanks for any help.

> 2 = ["key" => "A", "value" => 3]
> 3 = ["key" => "B", "value" => 4]
]

To group this array by both the "key" and "value" fields, you can use the following PHP code:

php
$array = [
["key" => "A", "value" => 1],
["key" => "B", "value" => 2],
["key" => "A", "value" => 3],
["key" => "B", "value" => 4]
];

$groupedArray = [];

foreach ($array as $item) {
$groupedArray[$item['key']][$item['value']] = $item;
}

print_r($groupedArray);


This code will output the following grouped array:


Array
(
[A] => Array
(
[1] => Array
(
[key] => A
[value] => 1
)

[3] => Array
(
[key] => A
[value] => 3
)

)

[B] => Array
(
[2] => Array
(
[key] => B
[value] => 2
)

[4] => Array
(
[key] => B
[value] => 4
)

)

)


This code groups the original array by the "key" field first, and then by the "value" field within each group.
