到目前为止，我有三个数组，它们像这样从数据库返回值（经过多次格式化）

[0]=>array(
           [0]=>'Apr', [1]=> 1), 
[1]=>array(
           [0]=>'May', [1]=>2), 
[2]=>array(
           [0]=>'Jun', [1]=>23)

具有相似值的第二个数组：

[0]=>array(
           [0]=>'Mar', [1]=>22),     
[1]=>array(
           [0]=>'Apr', [1]=> 1), 
[2]=>array(
           [0]=>'May', [1]=>2), 
[3]=>array(
           [0]=>'Jun', [1]=>25)

第三个：

[0]=>array(
           [0]=>'Jan', [1]=>50),     
[1]=>array(
           [0]=>'Feb', [1]=> 20), 
[2]=>array(
           [0]=>'Mar', [1]=>16), 
[3]=>array(
           [0]=>'Jun', [1]=>5)

这就是我试图使它们成为的方式：

[0]=>array(
           [0]=>'Month', [1]=>'Calc1', [2]=>'Calc2', [3]=>'Calc3'),     
[1]=>array(
           [0]=>'Jan', [1]=>0, [2]=>0, [3]=>50), 
[2]=>array(
           [0]=>'Feb', [1]=>0, [2]=>0, [3]=>20), 
[3]=>array(
           [0]=>'Mar', [1]=>0, [2]=>22, [3]=>16),
[4]=>array(
           [0]=>'Apr', [1]=>1, [2]=>1, [3]=>0),
[5]=>array(
           [0]=>'May', [1]=>2, [2]=>2, [3]=>0),
[6]=>array(
           [0]=>'Jun', [1]=>23, [2]=>25, [3]=>5)

请注意“0”是如何填充到不包含值的地方的。老实说，这是我遇到过的最复杂的数组问题，原因是遍历数组很困难。我特别需要数组是这种结构，因为我需要将它发送到 Google Visualization Area Chart。

如果您发现任何有关此问题的建议，请发布。

提前非常感谢你:)

@DevZer0：这是我得到的输出（带有我的真实数据）。请注意月份如何重复：

   array(
        [0] =>
            array(
                  [0] =>'Month'
                  [1] =>'Calc1'
                  [2] =>'Calc2'
                  [3] =>'Calc3'
                 )
        [1] =>
            array(

                  [0] =>'Apr'
                  [1] =>1
                  [2] =>0
                  [3] =>0
                  )
        [2] =>
            array(

                  [0] =>'Jun'
                  [1] =>9
                  [2] =>0
                  [3] =>0
                  )
        [3] =>
            array(

                  [0] =>'Apr'
                  [1] =>0
                  [2] =>1
                  [3] =>0
                  )
        [4] =>
                  array(

                  [0] =>'May'
                  [1] =>0
                  [2] =>2
                  [3] =>0
                  )
        [5] =>
                  array(

                  [0] =>'Jun'
                  [1] =>0
                  [2] =>23
                  [3] =>0
                  )
        [6] =>
                  array(

                  [0] =>'Apr'
                  [1] =>0
                  [2] =>0
                  [3] =>1
                  )
        [7] =>
                  array(

                  [0] =>'May'
                  [1] =>0
                  [2] =>0
                  [3] =>3
                  )
        [8] =>
                  array(

                  [0] =>'Jun'
                  [1] =>0
                  [2] =>0
                  [3] =>27
                  )
)

我希望它们以这种格式连接：

    array(
        [0] =>
            array(
                  [0] =>'Month'
                  [1] =>'Calc1'
                  [2] =>'Calc2'
                  [3] =>'Calc3'
                 )
        [1] =>
            array(

                  [0] =>'Apr'
                  [1] =>1
                  [2] =>1
                  [3] =>1
                  )
        [2] =>
            array(

                  [0] =>'May'
                  [1] =>0
                  [2] =>2
                  [3] =>3
                  )

        [3] =>
            array(

                  [0] =>'Jun'
                  [1] =>9
                  [2] =>23
                  [3] =>27
                  )

)

有没有办法做到这一点？再次感谢你：）

这不是一个难题，如果我理解正确的话，您有包含月份和整数的数组。假设您有 3 个数组，称为$array1, $array2,$array3

 $arrays = array($array1, $array2, $array3);
 $final = array();
 $index = 1;
 foreach ($arrays as $array) {
     foreach ($array as $ar) {
          if (!isset($final[$ar[0]])) {
              $final[$ar[0]] = array($ar[0], $index => $ar[1]);
          } else {
              $final[$ar[0]][$index] = $ar[1];
          }
     }
     $index++;
 }

 $final = array_values($final);

 for($x=0; $x < count($final); $x++) {
      for($i=1; $i < 4; $i++) {
          if (!isset($final[$x][$i])) $final[$x][$i] = "0";
      }
 }

 $header = array("Month", "Calc1", "Calc2", "Calc3");
 array_unshift($final, $header);

 var_dump($final); //will have your resulting array
