Question

我有一个场景，我从两个单独的文件中获取数据 - 一个.xml文件和一个.txt文件 - 我正在尝试使用PHP来组合2个数组（每个文件一个）来自每个的匹配值。

我无法控制上述文件的格式，所以使用以下代码我到目前为止已经放在一起：

<?php
function dir_to_array( $dir, $se ) { 

     $result = array(); 
     $cdir   = scandir( $dir ); 

    foreach ( $cdir as $key => $value ) {

        $file_info = pathinfo( $value );

        if ( ! in_array( $value, array( ".", ".." ) ) ) { 
            if ( is_dir( $dir . DIRECTORY_SEPARATOR . $value ) ) {  

                 $result[$value] = dir_to_array( $dir . DIRECTORY_SEPARATOR . $value ); 

            } else { 

                if ( $file_info['extension'] == 'xml' ) {

                    if ( isset( $se ) && $se !== 'undefined' ) {
                        if ( strpos( $value, $se ) !== false) {

                            $result['xml'] = xmlToArray( file_get_contents( $dir.'/'.$value ) );

                        } 
                    } 
                } 

                if ( $file_info['extension'] == 'txt' ) {

                    $file = fopen( $dir.'/'.$value, 'r' );
                    $count = 0;

                    while ( ( $line = fgetcsv( $file ) ) !== FALSE ) {
                        // trying to match the structure of the above array ($result['xml'])
                        $result['txt']['records']['PositionRecords']['record'][$count++] = $line;
                    }

                    fclose( $file );
                }

            }
        } 
    } 

    return json_encode( $result );
}

echo dir_to_array( 'path/to/something', $arg );

我能够获得以下数组：

数组1： _.xml

[records] => Array 
(
    [PositionRecord] => Array 
    (
        [record] => Array 
        (
            [0] => Array 
            (
                [keyword] => "something", // Value to match
                [position] => "1"
           ),
           ...
        )
    )
)

数组2： _.txt

[records] => Array 
(
    [PositionRecord] => Array 
    (
        [record] => Array 
        (
            [0] => Array 
            (
                [0] => "something", // Value to match
                [1] => "1000"
           ),
           ...
        )
    )
)

如何在匹配的keyword值上加入这些数组，最终得到如下数组：

[records] => Array 
(
    [PositionRecord] => Array 
    (
        [record] => Array 
        (
            [0] => Array 
            (
                [keyword] => "something",
                [position] => "1",
                [volume] => "1000" 
           ),
           ...
        )
    )
)

我尝试过使用array_merge，array_merge_recursive和array_combine，但它们似乎只是将一个数组附加到另一个数组。我还尝试了this answer和this answer，它们都返回一个空数组[]。

Answer 1

手动合并这些数组：

<?php

$a['records']['PositionRecord']['record'][0] = ['keyword'=>"something","position"=>"1"];
$a['records']['PositionRecord']['record'][1] = ['keyword'=>"something2","position"=>"2"];
$b['records']['PositionRecord']['record'][0] = ["something","1000"];
$b['records']['PositionRecord']['record'][1] = ["something2","2000"];


for($i = 0, $c = count($a['records']['PositionRecord']['record']); $i < $c; $i ++)
{
    $a['records']['PositionRecord']['record'][$i]['volume'] = $b['records']['PositionRecord']['record'][$i][1];
}

echo "<pre>";
var_dump($a);
echo "</pre>";

输出：

array(1) {
  ["records"]=>
  array(1) {
    ["PositionRecord"]=>
    array(1) {
      ["record"]=>
      array(2) {
        [0]=>
        array(3) {
          ["keyword"]=>
          string(9) "something"
          ["position"]=>
          string(1) "1"
          ["volume"]=>
          string(4) "1000"
        }
        [1]=>
        array(3) {
          ["keyword"]=>
          string(10) "something2"
          ["position"]=>
          string(1) "2"
          ["volume"]=>
          string(4) "2000"
        }
      }
    }
  }
}
