合并PHP数组以形成多维数组

我有以下两个阵列：

数组（[Jonah]=>27[Bianca]=>32

数组（[Jonah]=>2[Bianca]=>7

是否可以将它们合并在一起，形成这种格式的多维数组

Array ( [0] => Array 
               ( [name] => Jonah 
                 [age] => 27 
                 [number] => 2 )
        [1] => Array 
               ( [name] => Bianca 
                 [age] => 32 
                 [number] => 7 )
      )

按名称键控的临时数组存储前两个数组的值。然后将临时数组复制到以数字键控的最终数组：

$arr1 = array ( 'Jonah' => 27, 'Bianca' => 32 );
$arr2 = array ( 'Jonah' => 2, 'Bianca' => 7 );

$tmp = array();

// Using the first array, create array keys to $tmp based on
// the name, and holding the age...
foreach ($arr1 as $name => $age) {
 $tmp[$name] = array('name' => $name, 'age' => $age);
}

// Then add the number from the second array
// to the array identified by $name inside $tmp
foreach ($arr2 as $name => $num) {
  $tmp[$name]['number'] = $num;
}

// Final array indexed numerically:
$output = array_values($tmp);
print_r($output);

Array
(
    [0] => Array
        (
            [name] => Jonah
            [age] => 27
            [number] => 2
        )

    [1] => Array
        (
            [name] => Bianca
            [age] => 32
            [number] => 7
        )

)

注意：如果您同意按名称键入输出数组，则不需要严格执行复制数组以使其数字化的最后一步。在这种情况下，

$tmp

是最终产品。

确定。以下功能应满足您的需要：

$people = array ( 'Jonah' => 27, 'Bianca' => 32 );
$numbers = array ( 'Jonah' => 2, 'Bianca' => 7 );
$merged = array();
$i = 0;

foreach ($people as $k=>$v)
{
   if (isset($numbers[$k]))
   {
      $merged[$i]['name'] = $k;
      $merged[$i]['age'] = $v;
      $merged[$i++]['number'] = $numbers[$k];
   }
}

现在，如果您执行

var_dump（$merged）；

您将得到：

array
  0 => 
    array
      'name' => string 'Jonah' (length=5)
      'age' => int 27
      'number' => int 2
  1 => 
    array
      'name' => string 'Bianca' (length=6)
      'age' => int 32
      'number' => int 7

好的。以下功能应该会让你成为你想要的人：

$people = array ( 'Jonah' => 27, 'Bianca' => 32 );
$numbers = array ( 'Jonah' => 2, 'Bianca' => 7 );
$merged = array();
$i = 0;

foreach ($people as $k=>$v)
{
   if (isset($numbers[$k]))
   {
      $merged[$i]['name'] = $k;
      $merged[$i]['age'] = $v;
      $merged[$i++]['number'] = $numbers[$k];
   }
}

现在，如果您执行

var_dump（$merged）；

您将得到：

array
  0 => 
    array
      'name' => string 'Jonah' (length=5)
      'age' => int 27
      'number' => int 2
  1 => 
    array
      'name' => string 'Bianca' (length=6)
      'age' => int 32
      'number' => int 7
