How to sort multidimensionnal array from a single array?-CodePudding

I've got a multidimensionnal array :

[
  1 => [
   'name' => 'EC567'
   'type' => 'B3000'
   'value' => '4DFYU'
],
2 => [
   'name' => '1C527'
   'type' => 'B3UI0'
   'value' => '4DMNU'
]

]

And a single array which is my model :

['EC567', 'RD678','9O0PM','1C527']

I need to sort the multidimensionnal array by name from the single array which contains the list of all the names.

Any idea ?

You can use a custom sort function usort(), and use array_search() to order it using spaceship operator <=>.

Code (demo):

$arr = [
    1 => [
       'name' => 'EC567',
       'type' => 'B3000',
       'value' => '4DFYU',
    ],
    2 => [
       'name' => '1C527',
       'type' => 'B3UI0',
       'value' => '4DMNU',
    ]
];

$order = ['RD678', '9O0PM', '1C527', 'EC567'];

usort($arr, fn(array $a, array $b): int => 
    array_search($a['name'], $order) <=> array_search($b['name'], $order)
);

Output:

array(2) {
  [0]=>
  array(3) {
    ["name"]=> string(5) "1C527"
    ["type"]=> string(5) "B3UI0"
    ["value"]=> string(5) "4DMNU"
  }
  [1]=>
  array(3) {
    ["name"]=> string(5) "EC567"
    ["type"]=> string(5) "B3000"
    ["value"]=> string(5) "4DFYU"
  }
}

For PHP version lower than 7.4,

usort($arr, function(array $a, array $b) use($order): int {
    return array_search($a['name'], $order) <=> array_search($b['name'], $order);
});

$multiArray = [
    1 => [
     'name' => 'EC567',
     'type' => 'B3000',
     'value' => '4DFYU'
    ],
    2 => [
       'name' => '1C527',
       'type' => 'B3UI0',
       'value' => '4DMNU'
    ]
];

$singleArray = ['EC567', 'RD678','9O0PM', '1C527'];

$sortedArray = [];
for ($i=0; $i < count($singleArray); $i  ) {
    foreach ($multiArray as $key => $value) {
        if ($multiArray[$key]["name"] == $singleArray[$i]) {
            array_push($sortedArray, $multiArray[$key]);
        }
    }
}

print_r($sortedArray);

Output:

[0] => Array
    (
        [name] => EC567
        [type] => B3000
        [value] => 4DFYU

    (
