发现两个PHP数组匹配的元素，然后列出两个数组元素结合在一起

Question

Array 
(
    [0] => Array 
     (
      [0] => "Product Category" 
      [1] => Product Name 
      [2] => Product ID 
      [3] => Average Item Price 
      [4] => Item Sales 
      [5] => Items Sold 
      [6] => Product Conversion (Sold/Views) 
      [7] => Item Abandonment Rate 
     ) 
    [1] => Array 
     (
      [0] => OVERALL 
      [1] => - 
      [2] => - 
      [3] => $51.17 
      [4] => $1335974.77 
      [5] => 26111 
      [6] => 16.25% 
      [7] => 42.06% 
     ) 



ARRAY B: 
Array 
(
    [0] => Array 
     (
      [0] => "Content Category" 
      [1] => Page Name 
      [2] => Page Views 
      [3] => Sessions 
      [4] => Orders/Session 
      [5] => Sales 
      [6] => Bounce Rate 
      [7] => Page Views/Session 
     ) 

    [1] => Array 
     (
      [0] => OVERALL 
      [1] => - 
      [2] => 1017924 
      [3] => 135154 
      [4] => 16.57% 
      [5] => $1354866.20 
      [6] => 23.81% 
      [7] => 7.53 
     ) 

我想两个数组合并成一个......在那里，结果将类似于：

 
Array 
(
    [0] => Array 
     (
      [0] => "Product Category" 
      [1] => Product Name 
      [2] => Product ID 
      [3] => Average Item Price 
      [4] => Item Sales 
      [5] => Items Sold 
      [6] => Product Conversion (Sold/Views) 
      [7] => Item Abandonment Rate 
      [8] => "Content Category" 
      [9] => Page Name 
      [10] => Page Views 
      [11] => Sessions 
      [12] => Orders/Session 
      [13] => Sales 
      [14] => Bounce Rate 
      [15] => Page Views/Session 

     ) 
    [1] => Array 
     (
      [0] => OVERALL 
      [1] => - 
      [2] => - 
      [3] => $51.17 
      [4] => $1335974.77 
      [5] => 26111 
      [6] => 16.25% 
      [7] => 42.06% 
      [8] => OVERALL 
      [9] => - 
      [10] => 1017924 
      [11] => 135154 
      [12] => 16.57% 
      [13] => $1354866.20 
      [14] => 23.81% 
      [15] => 7.53 

     ) 

我只想输出匹配的阵列，其中“产品类别”==“内容类别”，并结合这两个数组元素...

我不太确定是否有一个预定义的函数，但我假设我必须做一些array_intersect（）或array_merge（）...主要的一点是抓住匹配的元素和将来自两个阵列的两个元素合并为一个，以便我可以进行一些后期处理计算...

谢谢！

Answer 1

我想通了，我的问题的答案..

// loop through ARRAY A 
for ($i = 0; $i < count($arrA); $i++) { 

    //loop through ARRAYB 

    for ($j = 0; $j < count($arrB); $j++) { 

     // if arrA value 0 matches arrB value 0 
     if ($arrA[$i][0] == $arrB[$j][0]) { 
      //append arrB to arrA 
      $arrA[$i] = array_merge($arrA[$i], $arrB[$j]); 
      break; 
     } 
    } 
} 

//clean out items 

for ($i = (count($arrA)-1); $i >= 0 ; $i--) { 

    if (count($arrA[$i]) < 16) { 
     unset($arrA[$i]); 
    } 
}

这将产生你要的数组：

$result = array(
    array_merge($A[0], $B[0]), 
    array_merge($A[1], $B[1]) 
);
