créer un tableau php basé sur un autre tableau.

Question

Je veux trier tous les tableaux PHP en fonction du premier tableau principal.

C'est le tableau principal que je veux utiliser pour trier tous les autres tableaux:

Array (

[0] => 10 
[1] => 14 
[2] => 15 
[3] => 20 
[4] => 21 
[5] => 24 
[6] => 25 
[7] => 28 
[8] => 30 
[9] => 45 
[10] => 60 
[11] => 90 
[12] => 120 
[13] => 150 
[14] => 180 
[15] => 210 
[16] => 240 
[17] => 270 
[18] => 365 

) 

Ce sont des tableaux qui doivent être triés:

Array (

[0] => Array 
    (
     [14] => 49.21 
     [20] => 71.04 
     [25] => 89.58 
     [30] => 100.00 
    ) 

[1] => Array 
    (
     [180] => 412.00 
     [150] => 347.00 
     [120] => 285.00 
     [90] => 224.00 
     [60] => 165.00 
     [30] => 100.00 
     [14] => 47.00 
    ) 

)

J'ai besoin ce résultat final ressemble à ceci:

Array (

[0] => Array 
    (
     [10] => n/a 
     [14] => 49.21 
     [15] => n/a 
     [20] => 71.04 
     [21] => n/a 
     [24] => n/a 
     [25] => 89.58 
     [28] => n/a 
     [30] => 100.00 
     [45] => n/a 
     [60] => n/a 
     [90] => n/a 
     [120] => n/a 
     [150] => n/a 
     [180] => n/a 
     [210] => n/a 
     [240] => n/a 
     [270] => n/a 
     [365] => n/a 
    ) 

[1] => Array 
    (
     [10] => n/a 
     [14] => 71.04 
     [15] => n/a 
     [20] => n/a 
     [21] => n/a 
     [24] => n/a 
     [25] => n/a 
     [28] => n/a 
     [30] => 100.00 
     [45] => n/a 
     [60] => 165.00 
     [90] => 224.00 
     [120] => 285.00 
     [150] => 347.00 
     [180] => 412.00 
     [210] => n/a 
     [240] => n/a 
     [270] => n/a 
     [365] => n/a 
    ) 

    ) 

Merci.

Answer 1

Si je comprends bien à partir de votre question, vous voulez faire les deux tableaux de la même longueur et mettre les clés non à "n/a".

Variant avec array_merge (Demo):

$shorten = array(
    0 => 10, 
    1 => 14, 
    2 => 15, 
    3 => 20, 
    4 => 21, 
    5 => 24, 
    6 => 25, 
    7 => 28, 
    8 => 30, 
    9 => 45, 
    10 => 60, 
    11 => 90, 
    12 => 120, 
    13 => 150, 
    14 => 180, 
    15 => 210, 
    16 => 240, 
    17 => 270, 
    18 => 365, 
); 

$data = array(
    0 => array(
    14 => '49.21', 
    20 => '71.04', 
    25 => '89.58', 
    30 => '100.00', 
), 
    1 => array(
    180 => '412.00', 
    150 => '347.00', 
    120 => '285.00', 
    90 => '224.00', 
    60 => '165.00', 
    30 => '100.00', 
    14 => '47.00', 
), 
); 

// default array as the base 
$shorten = array_combine($shorten, array_fill(0, count($shorten), 'n/a')); 

foreach($data as &$array) { 
    // merge to get set members 
    $array = array_merge($shorten, $array); 
} 
unset($array); 

var_dump($data);

Variant avec la fonction de mappage (Demo):

$shorten = array(
    0 => 10, 
    1 => 14, 
    2 => 15, 
    3 => 20, 
    4 => 21, 
    5 => 24, 
    6 => 25, 
    7 => 28, 
    8 => 30, 
    9 => 45, 
    10 => 60, 
    11 => 90, 
    12 => 120, 
    13 => 150, 
    14 => 180, 
    15 => 210, 
    16 => 240, 
    17 => 270, 
    18 => 365, 
); 

// overload $shorten array with a mapping function 
$shorten = function(array $a) use ($shorten) 
{ 
    $r = array(); 
    foreach($shorten as $i => $k) 
    { 
     $r[$k] = isset($a[$k]) ? $a[$k] : 'n/a'; 
    } 
    return $r; 
}; 


$data = array(
    0 => array(
    14 => '49.21', 
    20 => '71.04', 
    25 => '89.58', 
    30 => '100.00', 
), 
    1 => array(
    180 => '412.00', 
    150 => '347.00', 
    120 => '285.00', 
    90 => '224.00', 
    60 => '165.00', 
    30 => '100.00', 
    14 => '47.00',

); 

// apply mapping function to $data 
$data = array_map($shorten, $data); 

var_dump($data); # result

Answer 2

En supposant que votre tableau initial est $ source et todo $ est votre deuxième tableau avec les deux sous-ensembles, puis:

$keys = array_flip($todo); 
$keys = array_map(function() { return 'n/a'; }, $keys); // set all values to be "n/a"; 

foreach($todo as $idx => $do) { 
    $todo[$idx] = $do + $keys; // merge without renumbering. 
}
