Question

我正在尝试生产具有产品所有变体的阵列。可以有无限数量的属性和变体。

提供的数组：

["Shirt"]           # Product
    ["Color"]       # Attribute
        ["Green"]   # Variation
        ["Red"]
        ["Blue"]
    ["Size"]
        ["Small"]
        ["Medium"]
        ["Large"]

预期结果：

[0]
    ["type" => "Shirt"]
    ["color" => "Green"]
    ["Size" => "Small"]
[1]
    ["type" => "Shirt"]
    ["color" => "Green"]
    ["Size" => "Medium"]
...
[4]
    ["type" => "Shirt"]
    ["color" => "Red"]
    ["Size" => "Medium"]
[4]
    ["type" => "Shirt"]
    ["color" => "Red"]
    ["Size" => "Large"]

我已经尝试过Laravel和PHP的内置函数，但是没有成功。我真的很感谢任何见识。

Answer 1

使用三个嵌套的foreach，并在最后一级推送到$result数组。（在这里，我使用了compact函数来减少代码。）

$provided = [
    'Shirt' => [
        'color' => ['green', 'red'],
        'size' => ['Small', 'Medium'],
    ],
]; // Reduced the provided data to reduce the output for sample purposes.

$result = [];

foreach ($provided as $type => $attributes) {
    foreach ($attributes['color'] as $color) {
        foreach ($attributes['size'] as $size) {
            $result[] = compact('type','color','size');
        }
    }
}

var_dump($result);

将输出

array(4) {
  [0]=>
  array(3) {
    ["type"]=>
    string(5) "Shirt"
    ["color"]=>
    string(5) "green"
    ["size"]=>
    string(5) "Small"
  }
  [1]=>
  array(3) {
    ["type"]=>
    string(5) "Shirt"
    ["color"]=>
    string(5) "green"
    ["size"]=>
    string(6) "Medium"
  }
  [2]=>
  array(3) {
    ["type"]=>
    string(5) "Shirt"
    ["color"]=>
    string(3) "red"
    ["size"]=>
    string(5) "Small"
  }
  [3]=>
  array(3) {
    ["type"]=>
    string(5) "Shirt"
    ["color"]=>
    string(3) "red"
    ["size"]=>
    string(6) "Medium"
  }
}

您的问题似乎与我采用的这种通用方法很接近：

$arr = [
    'size'  => [ 'XS', 'S', 'M' ],
    'color' => [ 'yellow', 'brown', 'white' ],
    'weight'=> [
        'light' => [
                'super',
                'medium'
         ],
        'normal',
        'heavy' => [
            'regular',
            'most', 
            'overload'
        ]
    ]
];


function variations( $array ){

    if( empty( $array ) ) return [];

    function traverse( $array, $parent_ind ){
        $r = [];
        $pr = '';
        if( !is_numeric($parent_ind) )
            $pr = $parent_ind . '-';
        foreach( $array as $ind=>$el ) {
            if ( is_array( $el ) ) {
                $r = array_merge( $r, traverse( $el, $pr . ( is_numeric( $ind ) ? '' : $ind ) ) );
            }else
                if ( is_numeric( $ind ) )
                    $r[] = $pr . $el;
                else
                    $r[] = $pr . $ind . '-' . $el;
        }
        return $r;
    }

    //1. Go through entire array and transform elements that are arrays into elements, collect keys
    $keys = [];$size = 1;
    foreach( $array as $key=>$elems ) {
        if ( is_array( $elems ) ) {
            $rr = [];
            foreach ( $elems as $ind=>$elem ) {
                if ( is_array( $elem ) )
                    $rr = array_merge( $rr, traverse( $elem, $ind ) );
                else $rr[] = $elem;
            }
            $array[ $key ] = $rr;
            $size *= count( $rr );
        }
        $keys[] = $key;
    }

    //2. Go through all new elems and make variations
    $rez = [];
    for( $i = 0; $i < $size; $i++ ) {
        $rez[ $i ] = array();
        foreach( $array as $key => $value ){
            $current = current( $array[ $key ] );
            $rez[ $i ][ $key ] = $current;
        }
        foreach( $keys as $key )
            if( !next( $array[ $key ] ) ) reset( $array[ $key ] );
            else break;
    }

    return $rez;

}


die( print_r( variations( $arr ) ) );

结果将是“属性”或其他所有可能组合的数组（请参见下文）。我用它来创建Test Woocommerce Variable产品。
