Restructure array data by chunking, transposing, and merging

Question

I have array mentioned below, I will have value always multiple of 3.

$xyz = [
    ["name" => "abc"],
    ["name" => "snds"],
    ["name" => ""),
    ["number"=> "452"],
    ["number" => "845120"],
    ["number" => "84514513200"],
    ["email" => "ddddf"],
    ["email" => "dkskns"],
    ["email" => "kjnksdnkds"]
];

but this is not the proper format for me to perform further operations, so I want this array like mentioned below.

$abc = [
    [
        "name" => "abc",
        "number" => '452',
        "email" => "ddddf"
    ],
    [
        "name" => "snds",
        "number" => "845120",
        "email" => "dkskns"
    ],
    [
        "name" => "",
        "number" => "84514513200",
        "email" => "kjnksdnkds"
    ]
];

note: the array length is dynamic but it will always be multiple of 3

Answer 1

One possibility could be to use the modulo % operator.

In the foreach the value is an array and you could use array_keys to get the key and reset to get the value of the first array element.

$result = [];
$count = 0;
foreach ($xyz as $value) {
    if ($count%3 === 0) {
        $count = 0;
    }
    $result[$count][array_keys($value)[0]] = reset($value);
    $count++;
}

Demo

That will give you:

array(3) {
  [0]=>
  array(3) {
    ["name"]=>
    string(3) "abc"
    ["number"]=>
    string(3) "452"
    ["email"]=>
    string(5) "ddddf"
  }
  [1]=>
  array(3) {
    ["name"]=>
    string(4) "snds"
    ["number"]=>
    string(6) "845120"
    ["email"]=>
    string(6) "dkskns"
  }
  [2]=>
  array(3) {
    ["name"]=>
    string(0) ""
    ["number"]=>
    string(11) "84514513200"
    ["email"]=>
    string(10) "kjnksdnkds"
  }
}
