Question

我有以下数组包含2个元素：

$attribute_metric = array(2) 
{
  [0]=>
  array(2) {
    [0]=>
    string(5) "white"
    [1]=>
    string(6) " Black"
  }
  [1]=>
  array(3) {
    [0]=>
    string(1) "S"
    [1]=>
    string(2) " L"
    [2]=>
    string(2) " M"
  }
}

我希望以一种方式连接它的元素，我得到一个有6个元素的数组

array(6) {
  [0]=>
  string(8) "white, S"
  [1]=>
  string(8) "white, L"
  [2]=>
  string(8) "white, M"
  [3]=>
  string(8) "Black, S"
  [4]=>
  string(8) "Black, L"
  [5]=>
  string(8) "Black, M"
 }

我尝试了以下但是它不起作用：

$size = 1;
foreach ($attribute_metric as $key => $value) {
    $size = $size * sizeof($value);
}
foreach ($attribute_metric as $key => $value) {
    if($key > 0){
        foreach ($attribute_metric[0] as $subkey => $subvalue) {
            array_push($subvalue,$value);   
        }
    }
}

Answer 1

$array1= $attribute_metric[0]; //['white','black']
$array2= $attribute_metric[1]; // ['S', 'L', 'M']
$resultArray = [];  


foreach ($array1 as $color){
    foreach ($array2 as $size){
        $resultArray[] = $color . ', ' . $size;
    }
}

print_r($resultArray);

结果

Array
(
    [0] => white, S
    [1] => white, L
    [2] => white, M
    [3] => black, S
    [4] => black, L
    [5] => black, M
)

Answer 2

如果原始数组不是太大，那么使用嵌套循环将允许您生成所需的输出。

$colours=array('white','black');
$sizes=array('s','m','l');

$out=array();
foreach( $colours as $colour ){
    foreach( $sizes as $size ){
        $out[]=$colour.', '.$size;
    }
}
print_r( $out );

Answer 3

试试这个

<?php
$list = array(array('white','Black'), array('S','L','M'));
$result = array();
foreach ($list[0] as $k) {
    foreach ($list[1] as $t) {
        $result[] = $k.','.$t;
    }
}
var_dump($result);
?>

为了完整起见，如果你想只使用数组函数：

exec bash

php如何在一个数组中连接2个数组
