PHP下组合两个阵列的联合键

Question

我有以下两种阵列：

$Array1 = array(array('x1','x2','x3'),array('x4','x5','x6')); 
$Array2 = array(array('z1','z2','z3'),array('z4','z5','z6')); 

印刷它们时返回：

Array 
(
    [0] => Array 
     (
      [x1] => x1 
      [x2] => x2 
      [x3] => x3 
     ) 

    [1] => Array 
     (
      [x4] => x4 
      [x5] => x5 
      [x6] => x6 
     ) 

) 

Array 
(
    [0] => Array 
     (
      [z1] => z1 
      [z2] => z2 
      [z3] => z3 
     ) 

    [1] => Array 
     (
      [z4] => z4 
      [z5] => z5 
      [z6] => z6 
     ) 

) 

如何可以将它们结合起来以产生单个阵列状的例子下面，它们使用相同的键合并在一起：

Array 
(
    [0] => Array 
     (
      [x1] => x1 
      [x2] => x2 
      [x3] => x3 
      [z1] => z1 
      [z2] => z2 
      [z3] => z3 
     ) 

    [1] => Array 
     (
      [x4] => x4 
      [x5] => x5 
      [x6] => x6 
      [z1] => z4 
      [z2] => z5 
      [z3] => z6 
     ) 

) 

我试过使用：

array_merge=($Array1,$Array2) 

array_merge_recursive($Array1,$Array2) 

array_combine($Array1,$Array2) [which genereated an error, so I guess I was using it wrong] 

$数组1 + $数组2

，但这些都没有工作。

Answer 1

你要记住，你正在使用日ese在多维数组上的功能。你在正确的轨道与array_merge上，但你必须调用你的阵列的第二级，你将不得不遍历第一级

因此呼吁array_merge这些阵列，每个阵列的第二等级要素上应该工作：

$Array1 = array(array('x1','x2','x3'),array('x4','x5','x6')); 
$Array2 = array(array('z1','z2','z3'),array('z4','z5','z6')); 
$output = array(); 

foreach ($Array1 as $key=>$value) { 
    $output[$key] = array_merge($value, $Array2[$key]); 
    // same as: 
    //$output[$key] = array_merge($Array1[$key], $Array2[$key]); 
} 

，你将不得不在$输出终值

Answer 2

像这样的东西应该工作：

$output = array(); 
foreach ($Array1 as $key => $arr) { 
    $output[] = array_merge($arr, $Array2[$key]); 
} 

Answer 3

尝试

$Array1 = array_merge(array('x1','x2','x3'),array('x4','x5','x6')); 
$Array2 = array_merge(array('z1','z2','z3'),array('z4','z5','z6')); 

$Array = array_merge($Array1,$Array2) 

docs here

Answer 4

试试这个

$arr1 = array_merge($Array1[0],$Array2[0]); 
$arr2 = array_merge($Array1[1],$Array2[1]); 
$array = array($arr1, $arr2); 

Answer 5

这工作，即使你有没有数字指标：

$Array1 = array(array('x1','x2','x3'),array('x4','x5','x6')); 
$Array2 = array(array('z1','z2','z3'),array('z4','z5','z6')); 

$new_array = array(); 

foreach($Array1 as $key => $val) { 
    if(array_key_exists($key, $Array2)) { 
     $new_array[$key] = array_merge($val, $Array2[$key]); 
    } 
} 

echo '<pre>'; 
print_r($new_array); 
echo '</pre>'; 

Answer 6

试试这个。

<?php 
$Array1 = array(array('x1' => 'x1', 'x2' => 'x2', 'x3' => 'x3'), 
    array('x4' =>'x4','x5' =>'x5','x6' =>'x6')); 


$Array2 = array(array('z1' =>'z1', 'z2' =>'z2', 'z3' =>'z3'), 
array('z4' =>'z4','z5' =>'z5', 'z6' =>'z6')); 


$final=array(); 
foreach($Array1 as $key1=>$arr1) 
{ 
foreach($Array2 as $key2=>$arr2) 
    { 
    if($key1==$key2) 
    { 
     $sub=array_merge($arr1,$arr2); 
     $final[]=$sub; 
    } 
    } 
} 

echo '<pre>'; 
print_r($final); 
echo '</pre>'; 

?>
