如何使用指定的键重命名多维数组

Question

我正在尝试重命名此表单中第一个维度的所有数组键

Array
(
[0] => Array
    (
        [0] => Array
            (
                [0] => firstname17
                [1] => lastname17
            )

        [1] => Array
            (
                [0] => firstname7
                [1] => lastname7
            )

        [2] => Array
            (
                [0] => firstname18
                [1] => lastname18
            )

        [3] => Array
            (
                [0] => firstname12
                [1] => lastname12
            )

        [4] => Array
            (
                [0] => firstname3
                [1] => lastname3
            )

    )

[1] => Array
    (
        [5] => Array
            (
                [0] => firstname13
                [1] => lastname13
            )

        [6] => Array
            (
                [0] => firstname11
                [1] => lastname11
            )

        [7] => Array
            (
                [0] => firstname19
                [1] => lastname19
            )

        [8] => Array
            (
                [0] => firstname9
                [1] => lastname9
            )

        [9] => Array
            (
                [0] => firstname8
                [1] => lastname8
            )

    )

[2] => Array
    (
        [10] => Array
            (
                [0] => firstname10
                [1] => lastname10
            )

        [11] => Array
            (
                [0] => firstname2
                [1] => lastname2
            )

        [12] => Array
            (
                [0] => firstname4
                [1] => lastname4
            )

        [13] => Array
            (
                [0] => firstname16
                [1] => lastname16
            )

        [14] => Array
            (
                [0] => firstname15
                [1] => lastname15
            )

    )

[3] => Array
    (
        [15] => Array
            (
                [0] => firstname1
                [1] => lastname1
            )

        [16] => Array
            (
                [0] => firstname6
                [1] => lastname6
            )

        [17] => Array
            (
                [0] => firstname20
                [1] => lastname20
            )

        [18] => Array
            (
                [0] => firstname14
                [1] => lastname14
            )

        [19] => Array
            (
                [0] => firstname5
                [1] => lastname5
            )

    )

)

使用下面的php代码。当我运行它时，我在所有新的数组键中得到未定义的索引，试图保持从chunked数组进入的键。 "location1","location2","location3","location4","location5","location6","location"

<?php

$centers = array("location1","location2","location3","location4","location5","location6","location");
$row = '';
$filename =  'arrays.csv';
     $handle = fopen($filename, "r");      //Open file for reading
     if($handle){
       while (($data = fgetcsv($handle, ",")) !== FALSE){
        $state[] = $data;
         shuffle($state);
     }

        $newarray = array_chunk($state, 5, true);
        foreach($newarray as $key){
        foreach($centers as $newkey){
          $newarray[$newkey] = $centers[$newkey];

        }
}
      echo "<pre>";
     print_r($newarray);

   }
   ?>

编辑：预期输出应该如下所示

为了给他们新的密钥，您可以创建一个新密钥并将$centers分配给原始的chuncked数组。考虑这个例子:(我认为这是来自你之前的其他帖子）

$centers = array("location1","location2","location3","location4","location5","location6","location7");
$chunked_values = array( array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ), array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ), array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ), array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ), array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ), array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ), array( array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), array( 'firstname13', 'lastname13', 'Armstrong Landscaping', 'state1', 'email13', 'address13', ), ),);
$new_values = array();
foreach($chunked_values as $key => $value) {
    $new_values[array_shift($centers)] = $value;
}

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