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[]
。
答案 0 :(得分: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"
}
}
}
}
}
